Météo à Los Cabos (Cabo San Lucas) mois par mois

Cabo-forum threads on January weather call it the coolest month of the year here, warm 70s Fahrenheit afternoons against chilly low-60s mornings and evenings that make sweaters and light jackets worth packing for after dark. That's the extent of the downside, though - posters describe the month as crazy sunny, under half an inch of precipitation across the whole month, close to a guarantee of clear skies. The other big draw: January sits right in the middle of the December-15-to-April-15 whale migration season, prime time for sightings, and whales show up from the beaches and resort balconies too, binoculars recommended. The record: 25.8C days feeling like 26C, 16.9C nights, just 2mm across half a day, a 22.3C sea, 65 percent humidity and 9.7 hours of sun - dry, sunny, and cooler than the rest of the year without being cold.

March in Los Cabos is 75 to 85F by day, occasionally high 80s, 60s at night, and - the part regulars emphasise - without humidity. The water is the qualification: it averages around 72F, and the sea here is at its coldest from February through June, so snorkellers often bring a wetsuit even when the air is perfect. Whales are still about, with early March having them everywhere and sightings running into April. The other March fact is unavoidable: the whole month is spring break. The record: 27.9C days that feel like 30C, 19.2C nights, effectively no rain at all, humidity 63 percent and a 21.3C sea.

April in Los Cabos is the month regulars call perfect for air and awkward for water. Days run through the 70s into the low 80s Fahrenheit with evenings in the 60s, under blue sky and effectively no rain - our row records 0.1mm and zero precipitation days. The Sea of Cortez is the catch: about 23C, and March to May are the coldest water months of the year, so regular visitors describe it as brisk and several simply do not swim in it. Wind is the other April feature, stronger in Cabo San Lucas than at San Jose or Cabo Pulmo, usually a cooling onshore breeze but occasionally strong late in the month. The record: 30C days that feel like 32C, 21.4C nights, humidity 62 percent and 11.6 hours of sun.

Forum posters consistently describe May in Los Cabos as offering typical highs around 89F and lows around 61F, mostly in the mid-80s, with notably low humidity compared to other tropical destinations - a real comfort advantage posters flag repeatedly. Posters are direct that May tends to be windier than other months, with a local worker specifically calling it out as Cabo's windy season; the onshore breeze can turn brisk and cool but posters still generally rate the overall effect as pleasant rather than disruptive. Posters describe sea temperatures around 71F as on the cooler side for swimming this time of year. Posters consistently rate May favorably since spring break crowds have cleared out while school-summer crowds haven't yet arrived, making it a genuine sweet spot for good weather and lighter crowds together.

Cabo-forum threads on June weather are unusually unanimous: hot and dry, essentially no precipitation, exactly the combination regulars say they come here for. Multiple posters who visit every June for years running report never seeing a drop in the month, one specifically noting the previous year saw no precipitation at all through the entire stretch. Daytime highs run into the high 80s to 90 Fahrenheit with nights cooling into the upper 60s to low 70s, a real day-to-night swing that makes evenings genuinely comfortable after a hot afternoon. The ocean itself runs cooler than the air this time of year, refreshing rather than bathtub-warm. A steady breeze off the water is a regular feature, worth knowing if you plan time on the beach. May through early June together get called some of the most reliable weather of the whole year here. The record: 32.7C days feeling like a punishing 36C, 25.9C nights, just 14mm across 1.2 days, a 27.4C sea, 68 percent humidity and 12.5 hours of sun.

Cabo-forum threads on July weather run hot but not universally uncomfortable: daytime highs regularly into the mid-90s Fahrenheit, hot enough that regulars call it a desert climate with genuine ocean influence rather than the muggier heat of the Mexican mainland. Posters draw a specific contrast with August, tagging July as "hot and dry" against August's "hot and humid," though everyone agrees there's still real humidity in July. Nights are consistently praised as the redeeming feature, cooling desert-style to make evenings genuinely pleasant after a scorching afternoon. The water runs warm and beaches thin out compared to the winter high season. The standing advice is to go early in the month if given a choice, since conditions gradually intensify toward August. The record: 33.8C days feeling like a punishing 39C, 28C nights, just 17mm across 4.3 days, a 29.4C sea, 71 percent humidity and 12.4 hours of sun - hot and comparatively dry exactly as the forum frames it.

Cabo-forum threads on September weather are direct that it's the least favorable month by the numbers - hurricane season proper, hot and humid with the year's heaviest rainfall, and the standing advice is to check the tropical storm outlook before booking flights. That said, regulars are equally direct that most Septembers pass without a direct hit, delivering brief, heavy downpours that clear fast and leave the desert visibly greener along with some spectacular sunsets rather than a washed-out trip. A practical side effect: several restaurants close for part of the month since it's their slowest stretch, worth checking ahead. Prices and crowds both drop accordingly, the trade-off for the weather risk. The record: 32.3C days feeling like a sticky 39C, 26.6C nights, 120mm across 10.8 days, a 30.2C sea, 79 percent humidity and 10.7 hours of sun - the heaviest rain month on Cabo's whole calendar, exactly matching the hurricane-season framing.

Cabo forum threads are consistently glowing about November - highs in the low-to-mid 80s F, overnight lows in the low 60s, and rain so minimal it barely registers (posters cited around half an inch for the whole month). Humidity was described as dropping off noticeably compared to summer, making the heat feel far more comfortable. Water temperatures were reported in the mid-to-high 70s, still warm enough for swimming and snorkeling even as they ease down from their late-summer peak. The overall forum consensus: November through April is Cabo's best weather window, and November specifically combines warm days, cool nights and virtually no rain risk.
