Cabo San Lucas Weather by Month (2026)

Cabo San Lucas has one of the most reliable climates in Mexico: sunshine roughly 350 days a year, low humidity for most of the calendar, and a desert-meets-ocean setting where the biggest weather questions are how hot it will be and whether you are traveling during hurricane season. This month-by-month guide walks you through temperatures, sunshine, water temps, whale season, and the trade-offs of each part of the year so you can pick the dates that fit your trip.

Cabo's Two Seasons in a Nutshell

Cabo really has two seasons. The dry season runs from November through May: warm, sunny, low-humidity days and cool, comfortable nights. This is peak season, and for good reason. The humid and hurricane season runs from roughly June through October, hottest and stickiest in August and September, when the ocean is bath-warm but the tropical-storm risk is real. Neither season is bad, they simply suit different travelers.

Month-by-Month Weather

January & February

Peak dry season. Expect highs in the mid-to-upper 70s Fahrenheit, cool evenings that can dip into the 50s, near-zero rain, and endless sunshine. Water temps are on the cooler side, around 70°F, so swimming is refreshing rather than warm. This is prime whale-watching time and comfortable for hiking and full days outdoors.

March & April

Many locals' favorite months. Warm, dry, and sunny with highs climbing into the low 80s, gentle nights, and virtually no rain. The water starts warming up, crowds are lively but not unbearable, and whale season is still going through March into early April. If you want the best all-around weather of the year, this is it.

May

The tail end of the dry season and a sweet spot. Highs in the mid-80s, warm water approaching 75°F, low humidity, and reliably clear skies, all before the summer crowds and heat fully arrive. Excellent value and excellent conditions.

June & July

Summer heat settles in. Highs push into the upper 80s and low 90s, humidity begins to build, and the occasional bit of moisture appears, though serious storms are still uncommon this early. Water temps rise into the low 80s, making the ocean warm and inviting. Mornings and evenings are the time to be active.

August & September

The hottest, most humid, and most storm-prone stretch of the year. Highs in the 90s combine with high humidity to make midday genuinely hot, and September is statistically the peak of hurricane season in the region. Rain, when it comes, tends to arrive in short heavy bursts. The upside: the warmest water of the year (mid-80s), the lowest prices, and the fewest crowds. If you travel now, keep an eye on forecasts and consider travel insurance.

October

A transition month that gets better as it goes. Early October still carries some hurricane-season risk and lingering humidity, but by late in the month the air dries out, temperatures ease into the mid-to-upper 80s, and the water stays warm. The back half of October can be a hidden gem, warm, quiet, and increasingly reliable.

November & December

The dry season returns and Cabo is at its best again. Comfortable highs in the upper 70s to low 80s, cooler nights, low humidity, and abundant sunshine. Whale season begins in December, and the holiday period brings a festive buzz and higher prices. Book early if you want to be here for the holidays.

Water Temperatures & Whale Season

Ocean temperatures swing more than the air does. Expect cooler water around 70°F in the January-to-March window, warming steadily through spring, and peaking in the mid-80s from August into October. If bath-warm water for snorkeling and swimming is your priority, aim for late summer and early fall.

Whale season is a headline reason to visit in winter. Gray and humpback whales migrate to Baja's waters roughly from December through April, with peak sightings usually in January and February. Watching them breach offshore is one of Cabo's signature experiences. Our full Cabo whale watching guide covers the season, tours, and tips in detail.

So, When Should You Visit?

The answer depends on what you want out of the trip.

• Best overall weather: March through May, warm, dry, sunny, and reliable.
• Whale watching: December through April, with January and February at the peak.
• Warmest water: August through October, ideal for swimming and snorkeling.
• Best value and fewest crowds: late spring and the shoulder of late October, when prices dip but the weather still delivers.
• Weather to plan around: August and September, the hottest, most humid, and most storm-prone months.
