🔎 TL;DR
- The Los Cabos SUP year is governed by one weather pattern: the El Norte thermal wind that blows down the Sea of Cortez from November through April, killing the afternoon paddling window and leaving only the dawn lull.
- May through October is the calm half — light winds, warm water (24–29 °C), and the only months when you can paddle into late morning without fighting chop.
- August–October overlaps hurricane season per NOAA NHC — most days are calm but a single named storm can shut the cape for a week.
- Water temperature drops to 18–20 °C on the Pacific side in Jan–Feb per NOAA sea-surface temperature charts; Cortez side stays warmer at 20–22 °C.
- The honest one-line answer: book your SUP for May, June, September or October if you want full mornings; book January through April if you only need a 6–9 am sunrise window and can accept cooler water.
- El Norte sometimes drops below 10 knots even in winter — track the forecast on Windguru for "Cabo San Lucas" and "Los Barriles" stations 72 hours out.
Reading the Los Cabos weather year
The cape has two seasons and the dividing line is the wind. El Norte is the thermal pressure-gradient wind that blows from the high-pressure cell that sits over the south-western United States and northern Baja in winter, pushing air down the long fetch of the Sea of Cortez. It is famous to kite and windsurf travellers — Los Barriles, La Ventana, and the East Cape are world-class wind destinations precisely because of El Norte. For SUP paddlers, the same wind is the limiting factor. From late October until late April, the cape's afternoons are unusable for paddling on any open water, and the only sane window is sunrise — typically a two-to-four-hour calm before the thermal kicks in.
The mirror season runs May through October. The pressure gradient collapses, the trade-wind influence weakens, and the cape sits in light variable winds with warm water. This is when corridor beaches stay paddleable until 11 am or later, when East Cape sessions go all morning, and when SUP-snorkel combos at Chileno and Santa María hit their best visibility. The catch is hurricane season: the Eastern Pacific hurricane season officially runs May 15 to November 30 per the National Hurricane Center, with peak activity August–October. Most named storms track north along the Mexican Pacific coast or recurve out to sea, but a direct hit or close pass — Odile in 2014, Newton in 2016 — can shut the cape for a week or more.
Below we walk through every month with the data points that matter for SUP planning: prevailing wind direction and strength, water temperature, swell exposure, visibility for SUP-snorkel, and whether you want to be here.

Notes: AM wind is the typical 6–10 am average; PM wind is the typical 12–4 pm average. "N" indicates the El Norte from the north / north-west; "var" indicates variable summer flow. Water temperatures are operational averages from local SUP guides reconciled with NOAA Ocean Service SST data for the southern Gulf of California. Swell risk reflects both Pacific south swells (May–Oct) and seasonal hurricane risk.

November to April — the El Norte winter
The El Norte half of the year is what kite and windsurf travellers come for, and what SUP paddlers must respect. The pattern is predictable: calm dawn, building wind by 10 am, fully developed 15–25 knot north or north-westerly by 1 pm, easing again after sunset. A handful of "off" days each month — when a passing low or a high-pressure shift breaks the gradient — drop the wind into the single digits all day. These are the days every SUP guide in Cabo wants. You can't book them, but you can position yourself: come in winter with five days flexible, watch Windguru and Windy daily, and on the calm days you go.
December–January
Cooler air (high 18–22 °C, low 12–15 °C) and the coldest water of the year on the Pacific side (~18 °C in February dips). On the Cortez side it holds 20–22 °C. A 3 mm shorty or 2 mm long sleeve is comfortable for a 90-minute dawn SUP. Whale-watching season opens in mid-December as grey and humpback whales arrive — paddling sessions on the East Cape will often see whale spouts in the distance from the board. We cover the marine-life side in our safety guide.
February
Statistically the windiest month — El Norte is fully developed and the gradient is at its sharpest. Average afternoon wind 18–25 knots at Los Barriles per Windguru. Corridor beaches still get a calm dawn window most days, but it is shorter — often only 6:30 to 9:00 am. Water is coldest; a 3 mm shorty is the practical minimum.
March–April
The slow exit from winter. Wind direction stays north but average strength drops through April. Water warms back into the low 20s. By late April the dawn window stretches back to 10:30–11:00 am on a typical day, and SUP-snorkel at Chileno becomes pleasant again as visibility climbs back to 15–20 m. These are honest sunrise months for cape SUP if you don't mind the chance of an aggressive thermal cutting your session at 10 am.
May to October — the calm half
The flip is fast. By the second week of May the pressure gradient collapses, the El Norte goes dormant, and Cabo enters its mirror season: light variable winds, warm air (28–32 °C daytime), warm water, and a long usable SUP morning that often stretches through noon. From a pure SUP perspective these are the months you want. From a Cabo-as-a-destination perspective, summer also means heat, humidity, hurricane risk, and bigger summer crowds at corridor beaches.
May–June
The window. Wind is at its calmest of the year, water temperature climbs through the 20s, and hurricane season has not really started. June is statistically the driest month in southern Baja per SMN climatology. For a casual traveller who wants two morning SUP sessions plus a Chileno snorkel afternoon, June is the answer. Crowds at corridor beaches are moderate (US summer break starts late June).
July
Hot. Air temperature into the mid-30s, water 26–28 °C, occasional thunderstorm cells building over the inland mountains. The cape itself usually stays clear in the morning. Hurricane season ramps up but the first systems usually track far west out to sea. Crowds peak with US and Mexican summer break overlapping.
August–September
The hottest and most humid months — and the peak of the eastern Pacific hurricane season per NHC. Most days are calm and paddleable, but the probability of a named storm passing within 200 nm of the cape is at its highest. Travellers who book August or September should budget two flexible days in case a system shuts the cape. SUP-snorkel visibility at Chileno can also drop during storm swells. The trade-off: water is at its warmest (28–29 °C), and the mid-summer mobula ray season peaks at the East Cape — paddling in 4 m of clear water with rays jumping a metre out of the water is one of the things you remember about Cabo.
October
The traveller's hidden window. Hurricane season tails off through October, crowds drop after Labor Day, water is still 25–28 °C, and the El Norte has not started yet. Some seasons it stays calm all month; others — depending on when the first cold front passes — the El Norte ramps in by late October. Late October is a calculated risk that often pays off.
Hurricane risk and what it actually means for your trip
The Eastern Pacific hurricane basin is the second-most-active in the world after the Atlantic, and Los Cabos sits at the northern end of the basin's track climatology. Per NHC historical data, the basin averages 15 named storms, eight hurricanes, and four major hurricanes per year. The peak month for direct or close-pass impacts on the southern Baja peninsula is September. The practical reality for a traveller: most named storms in the basin do not affect Los Cabos. They form well offshore and recurve north-west into open ocean. The ones that do affect Los Cabos are usually the systems that form in the southern part of the basin off Colima/Michoacán and track north-north-west along the Mexican coast.
What this means for your SUP plans: if you book August–October, watch the NHC outlook starting five days before your trip. If a system is in the basin and the cone of probability includes Los Cabos, plan around it — book an extra day at either end of your trip, or have a back-up indoor activity for the day of closest approach. Once a storm passes, the cape's waters can take 48–72 hours to settle: surge swell, churned-up turbidity, debris on beaches. Operators will not run SUP-snorkel in that window even if the wind drops. The full picture also depends on whether the storm makes landfall (worst case) or passes offshore (recoverable in 24–48 hours).
Water temperature and wetsuit choices
The Cabo water-temperature year is more dramatic than first-time visitors expect. The Pacific side stays the coldest, ranging from a low of 17–19 °C in February to a high of 25–27 °C in September. The Cortez side stays a few degrees warmer year-round: 20–22 °C in February, 28–30 °C in September. For SUP, the relevant question is whether you need a wetsuit. SUP is a low-immersion activity — most of the time you are dry on the board — so the wetsuit question is really "what happens if I fall in for ten minutes". Our practical recommendations:
- Dec–Apr, Cortez side (Medano, Chileno, Santa María, La Ribera): 2 mm shorty for comfort; not strictly required for short sessions.
- Dec–Apr, Pacific side (Cerritos, etc.): 3 mm full or 2 mm long sleeve. The Pacific is genuinely cold in winter.
- May–Oct, anywhere: nothing — rashie and shorts. Water is warm enough that immersion is pleasant.
- SUP-snorkel combo (Chileno, Santa María) in winter: 2 mm shorty minimum for the snorkel portion; the moment you stop moving in 20 °C water, you cool down fast.
Local SUP and snorkel operators rent wetsuits cheaply ($10–15 USD/day). Most casual travellers do not bring their own. If you are SUPing daily for a week in January–February, a personal 2 mm shorty saves money and saves you waiting in line for rentals.
Visibility for SUP-snorkel by month
If you are combining SUP with snorkel at Chileno or Santa María — which most travellers do — water clarity is the variable that decides whether the trip lives up to the postcard. Two factors drive it: wind chop (which stirs the surface and reduces clear viewing) and swell (which lifts sand off the reef and turbid es the water). Best clarity months on the corridor are April–June and October–November — the shoulder windows when wind is light and hurricane swell is minimal. Worst clarity months are February (sustained El Norte chop) and August–September (storm swell).
Practical SUP-snorkel visibility numbers, averaged across local operator reports:
| Month | Chileno viz | Santa María viz | Reef quality |
|---|---|---|---|
| Jan–Mar | 10–15 m | 8–12 m | Good when calm |
| Apr–Jun | 15–25 m | 15–20 m | Excellent |
| Jul | 15–20 m | 12–18 m | Good |
| Aug–Sep | 8–15 m | 6–12 m | Variable, storm-driven |
| Oct–Nov | 15–25 m | 15–20 m | Excellent |
| Dec | 12–18 m | 10–15 m | Good |
Best month if you only have one trip
If we had to pick one month to recommend a SUP-first Los Cabos trip, it is June. Wind is at its calmest of the year, water is comfortably warm (24–27 °C) but not yet at peak summer heat, hurricane season has barely begun, and crowds are moderate. SUP-snorkel visibility at Chileno is at its best of the year. East Cape sessions out of La Ribera run all morning without El Norte interference. If June doesn't fit, May and early October are the next best calls — both shoulder months between weather seasons, both with high paddleable-day percentages, both quieter than peak summer.
The hardest month for SUP-focused travel is February. Sustained El Norte, coldest water of the year, shortest dawn window. February is excellent for kite and windsurf; for SUP it is the month where the most days get cut short. If you are coming in February, manage expectations and plan to be at the launch by 6:15 am.
Frequently asked questions
When is the absolute best month for SUP in Los Cabos?
June — calmest wind of the year, warm but not blistering water, low hurricane risk, peak SUP-snorkel visibility at Chileno (15–25 m). If June doesn't fit, May and early October are the next-best windows. Avoid February if you can; it is the windiest and coldest month and the dawn window is shortest.
Can I still paddle in winter (Dec–Mar)?
Yes — but only at sunrise. The El Norte thermal wind builds by 10 am most winter days and runs 15–25 knots through the afternoon. A typical winter SUP day in Cabo is: launch at 6:15 am, paddle for 90 minutes, off the water by 8:30 am. Inside that window the water is glass and the lighting is beautiful. After 10 am, switch to a non-water activity.
Will a hurricane ruin my trip if I book August or September?
Probably not, but plan for the possibility. Most named storms in the eastern Pacific basin never affect Los Cabos — they form and recurve out to sea. The ones that do affect Los Cabos can shut the cape for 3–7 days. If you book August or September, watch the NHC outlook starting five days before your trip and budget one flexible day at each end. Operators do not run SUP-snorkel for 48–72 hours after a close pass, even if the wind drops.
Do I need a wetsuit?
Depends on the month and the side of the peninsula. Cortez side (Medano, Chileno, Santa María, East Cape) Dec–Apr: a 2 mm shorty is comfortable for SUP-only sessions; required for SUP-snorkel combos. Pacific side (Cerritos area) Dec–Apr: 3 mm full or 2 mm long sleeve. May–Oct anywhere: nothing needed, rashie and shorts. Rental wetsuits run $10–15 USD per day if you don't bring your own.
How does El Norte compare to Caribbean trade winds in Cancún?
Different beast. Cancún has steady trade-wind chop almost year-round but the wind is moderate (10–18 knots average) and offshore from land, so the lagoon side (Nichupté) is protected and paddleable all day. Cabo's El Norte is a thermal pressure-gradient wind that builds from nothing to 20+ knots in two hours and blows across long fetch — there is no protected backside on the Cortez. That is why Cancún SUP is "any time of day if you pick the right side" and Cabo SUP is "dawn only in winter". We compare both in detail in SUP Los Cabos vs Cancún.
