Cabo San Lucas

The sea cools to 70 in February, and the first plunge tells you so. It wakes you up rather than warns you off, and most swimmers are back in within minutes. On land the numbers sit close to ideal, afternoons at 76, nights at 64, and just 7 mm of rain across the entire month. That is dry enough that shade, not shelter, is the only real planning question for a beach day. Evenings ask for a light sweater on deck and nothing more. February sits square in prime season, so expect company on the popular sand and out on the bay. One wrinkle is worth knowing. Día de la Constitución falls this month, and public holidays can shift opening hours for shops and services near the tender pier. Check the date against your itinerary, then go claim your patch of beach while the weather does exactly what the brochure promised.

By March the rain has all but quit. The monthly total is 2 mm, which in practice means none, and the sky behaves accordingly. Days warm to 78 while nights hold at 65, comfortable for a long dinner outside without reaching for a jacket. The sea stays at 70, refreshing rather than warm, a quick reset between stretches of dry heat on the sand. Prime season continues, with the crowds that label implies. What sets March apart is the holiday calendar, which is unusually full: Natalicio de Benito Juárez, Jueves Santo, and Viernes Santo can all shorten opening hours ashore, so a quick check of the dates before you tender in saves finding a locked door later. Get past that bit of admin and the month is simple. Sun, dry sand, cool water, and daylight that stretches pleasantly into the evening.

Rain simply does not happen in a typical April. The monthly total is 0 mm, and that certainty changes how you plan a shore day. No backup, no umbrella, no anxious glance at the forecast. Afternoons reach 80 and nights stay at 67, warm enough that sail-away is a shirtsleeves affair. The sea holds at 70, still on the cool side, which makes the first swim bracing and every one after it easy. Prime season rolls on, and April earns the billing with dry heat that stops well short of oppressive. The date to watch is Día del Trabajo, a public holiday that can affect opening hours for shops and services ashore, so confirm what will be open if your call coincides. Beyond that, the month is about as low-risk as cruise weather gets, with guaranteed sun, a bay that behaves, and the arch at Land's End posing against a cloudless sky.

The thermometer starts its climb in May. Afternoons reach 83, nights hold at 71, and the sea answers by warming to 73, an easy temperature for a long swim rather than a quick dip. Rain stays a technicality at 1 mm for the month, so the sky remains a reliable partner for anything you book on the water. The extra warmth shows up most in the evenings, when 71 means dinner outside without a second thought and a late walk on deck in short sleeves. The month sits comfortably in the prime climate band, warm without tipping into heavy heat, and it carries no flagged public holidays, so opening hours ashore run to their normal rhythm. Planning gets easy. Pack for sun, put the bay at the center of the day, book the water activity you have been hesitating over, and let the month do the rest.

June is when Cabo turns properly hot. The typical high reaches 86 and the night barely dips to 75, so the day starts warm and stays there. The real news is the water: 79 degrees, the kind of sea you walk into without a flinch and leave reluctantly. Rain stays minimal at 4 mm, so the extra heat arrives with the same dependable sky. The practical playbook shifts a little. Do the walking early, save the middle of the day for the bay, and treat shade as a destination rather than an afterthought. Evenings at 75 keep the deck comfortable long after sunset, no layer required. Prime season continues, and the month rewards anyone whose shore plan is built around swimming. The sea has warmed to the point where time in the water stops being an activity and becomes the default, and the beach is simply where you dry off between rounds.

Two seasons share July. Most days belong to the first, with highs of 87, a sea at 82 that feels like an extension of the air, and hour after hour of hard sunshine. The second shows up as 22 mm of rain across the month, enough that a passing shower is possible, not enough that anyone builds a day around avoiding one. Nights hold at 78 and never truly cool, so evenings on deck stay warm and an early start ashore beats the afternoon heat. The water is the point now. At 82 the bay invites long, unhurried swims, and the gap between air and sea temperature nearly disappears, so there is no shiver on the way out. Prime season continues through the heat, so expect fellow cruisers wherever the sand is good. Hydrate more than feels necessary, claim your shade early, and give the middle of the day to the water.

Everything peaks at once in August. The afternoon high tops out at 88, nights stay at 80, and the sea reaches 86, close enough to the air that getting in and out of the water barely registers as a change. Rain becomes a real presence too, 57 mm over the month, usually enough to interrupt an afternoon rather than erase a day, but worth a flexible plan for anything time-sensitive ashore. This is heat that sets the agenda. Mornings are for moving, middays are for floating, and shade is currency on the sand. The reward is a bay at its warmest, where you can stay in as long as you like and come out no cooler than you went in. Prime season continues on the cruise calendar, so the heat does not thin the crowds much. Pack the lightest clothes you own, drink water constantly, and let the sea handle the air conditioning.

An afternoon shower is now a genuine possibility. September carries 68 mm of rain, a total that earns a line in your shore plan, though a shower at these temperatures interrupts a day rather than cancels it. The heat barely blinks, 87 by day, 80 at night, with the sea holding at 85, which turns any rainy interlude into a reason to stay in the water anyway. Warm rain over a warm bay is not much of a hardship. The month also brings Día de la Independencia, a public holiday that can affect opening hours for shops and services, so check the date before building a day around one specific stop ashore. Otherwise the September rules are short. Start early, keep the afternoon loose, and treat the sea as the sure thing on the schedule. At 85 degrees, it always is.

The heat has not gotten the memo about autumn. October afternoons still reach 87, nights hold at 78, and the sea sits at 85, numbers that would read as high summer almost anywhere else. Rain totals 36 mm for the month, enough that the occasional shower happens, not enough that a shore day is ever in any serious danger. The formula is familiar by now. Early starts for anything on foot, the middle of the day for the bay, evenings warm enough that plans on deck need no contingency. The water remains the headline. At 85 it asks nothing of you, no bracing, no adjustment period, just an easy wade off the sand and no reason to hurry back out. October sits in the prime climate band with no flagged holidays, so opening hours ashore should run at their usual rhythm. The weather will not be your reason to hesitate.

Nights cool first. By November they settle at 72, a shift you feel on the evening tender back more than anywhere else, while afternoons hold a warm 83. The sea reads 81, still comfortably swimmable, and rain retreats to 15 mm for the month, so the sky mostly stays out of your way. It is a month of easing rather than upheaval. Warm days, softer nights, water that welcomes you without summer's full weight of heat around it. Prime season conditions continue. The date to note is Día de la Revolución, a public holiday that can affect opening hours for shops and services ashore, worth a check if your call lands on it. Beyond that, November plans itself. Beach in the morning or the afternoon, a swim whenever the mood strikes, and a light layer in your bag for the ride back across the bay at dusk.

A 78-degree afternoon is Cabo's idea of deep winter. December pairs that with nights at 67, cool enough for a sweater at dinner and nothing heavier, and a sea still holding 77, a leftover of the warm months behind it. Rain is minor at 13 mm, so a full beach day carries little weather risk even this late in the year. Prime season conditions in the middle of the northern winter are the whole appeal. You left the cold at home, and the water here is warmer than the air. Navidad falls this month, and the public holiday can affect opening hours for shops and services ashore, so check what will be open if your call lands on or near it. Then do what December in this port is for. Swim in the sea, dry off in the sun, and compose a suitably casual message to the people shoveling snow back home.
