A Month-by-Month Guide to the Best (and Worst) Months

Best Time to Visit Cabo San Lucas: A Month-by-Month Guide to the Best (and Worst) Months

Quick answer: The best time to visit Cabo San Lucas is April through June and late October through November. These shoulder months deliver dry, 80–90°F days, calm seas, thin crowds, and villa rates well below peak winter pricing. The worst months to go to Cabo are August and September, when humidity peaks, rain concentrates, and Pacific storm risk is highest. If whale watching is your priority, visit mid-December through mid-April instead.

Los Cabos gets more than 350 sunny days a year, so there is no truly bad week here, only trade-offs between weather, price, and crowd size. This guide breaks those trade-offs down month by month so you can book the exact window that fits your trip.

Cabo Weather by Month: The Numbers Travelers Actually Need

monthly guide to los cabos travelers

Cabo San Lucas sits in a desert that meets the sea, which is why it stays dry while mainland Mexican beach towns get soaked. Average annual rainfall totals under 10 inches, and more than half of it falls in just two months.

Temperature and precipitation averages sourced from the National Climatic Data Center.

Two patterns jump out. First, March through June is functionally rainless, under a tenth of an inch across four months. Second, August and September account for roughly 60% of Cabo’s yearly rainfall, which is the single clearest reason those months rank last.

The Best Months to Visit Cabo San Lucas: April to June

Ask a repeat traveler for the best month to visit Los Cabos and you’ll usually hear May or June. Here’s why that window wins:

    1. Spring break has cleared out. The college crowd peaks in March and early April. By May, downtown Cabo and the beaches feel like a different destination.
    2. The water warms up. Sea temperatures climb into the upper 70s, making snorkeling at Chileno Bay and Santa María Bay far more comfortable than in winter.
    3. Rain is essentially zero. June averages no measurable rainfall at all.
    4. Rates soften before summer. Villa and resort pricing drops noticeably once peak season ends, without the humidity trade-off that arrives in July.

April is the bridge month: temperatures in the mid-80s, whale season tailing off through mid-April, and Easter week the only real crowd spike. If you want warm water plus the last chance at a humpback sighting, the first half of April is the sweet spot.

The Second-Best Window: Late October Through November

Fall is Cabo’s most underrated season, and for snorkelers and divers it may genuinely be the best.

  1. Warmest water of the year. Ocean temperatures often sit in the low 80s in October and November, with peak visibility.
  2. Sargassum-free. Unlike Cancún and the Riviera Maya, Los Cabos stays clear of sargassum seaweed year-round.
  3. World-class sportfishing. Bisbee’s Black & Blue Marlin Tournament — the richest fishing tournament on earth — fills the marina in late October.
  4. Cooler evenings return.

    November nights drop into the low 60s, perfect for terrace dinners and open-air villa living.

November also brings Día de los Muertos altars in San José del Cabo’s Art District and the Los Cabos International Film Festival. Book early: hotel and villa rates start climbing by mid-November as peak season approaches.

The Cheapest Time to Visit Cabo: July Through September

If budget drives your decision, July, August, and September deliver the deepest discounts of the year, often 30–50% below winter rates at the same property. Five-star resorts and private villas that are impossible to book in February become surprisingly attainable.

What you’re trading:

  • Daytime highs in the low 90s with real humidity
  • The majority of Cabo’s annual rainfall, concentrated in August and September
  • Elevated tropical storm risk (more on that below)
  • Some smaller attractions and restaurants closing for the season

What you’re gaining: near-empty beaches, restaurant tables without reservations, and a private villa at shoulder-season pricing. For travelers who plan to spend their days in a pool with an ocean view, it’s a legitimate value play — as long as you buy travel insurance and watch the forecast.

A gentler discount option:  May and early June give you 80% of the savings with almost none of the weather risk.

The Worst Months to Go to Cabo and the Honest Caveats

August and September: Peak Heat, Peak Rain

These are the two months to avoid if weather matters most. August is the hottest month of the year, September the wettest. Together they carry the highest practical storm risk of the year.

Cabo Hurricane Season, Explained

The Eastern Pacific hurricane season officially runs May 15 to November 30, but the real risk window for Los Cabos is much narrower: late August through early October. Cabo’s position at the tip of the Baja peninsula means it far more often gets tropical storms — wind, a day or two of rain, then blue sky — than direct hurricane landfall. Direct hits are rare but not unheard of, which is why travel insurance is non-negotiable in this window.

March and Early April: The Crowd Problem

March isn’t bad weather-wise — it’s one of the driest months on the calendar. It’s bad for a different reason: spring break. From late February through early April, US student travel floods downtown Cabo. If you’re planning a family trip, an anniversary, or a quiet villa week, this is the season to skip.

December Through February: The Price Problem

Peak season brings ideal 77–80°F days and the highest rates and occupancy of the year. Nothing is wrong with winter in Cabo, it’s simply the most expensive and most crowded way to experience it.

Best Time to Visit Cabo by Travel Style

  1. Whale watching: Mid-December to mid-April, peaking January–March. Whale sharks near La Paz run October–April as a separate full-day trip.
  2. Snorkeling and diving: October and November, with Cabo Pulmo Marine Park as the day-trip prize.
  3. Surfing: Costa Azul and the Sea of Cortez side, April–October. Cerritos on the Pacific side is best for beginners, December–February, usually with a wetsuit.
  4. Sportfishing: Year-round. Marlin September–January, tuna June–January, yellowtail January–April.
  5. Families: April, May, early June, or November — warm water, manageable crowds, no spring break overlap.
  6. Couples and honeymooners: May, June, or late October for privacy and value.
  7. Budget travelers: July through September.
  8. Food and culture: December for Sabor a Cabo, February for San José Jazz Weekend, March for the Festival of San José.

A Safety Note Most Cabo Guides Skip

Many Los Cabos beaches are not safe for swimming at any time of year, regardless of how calm they look. Steep drop-offs, heavy shore break, and strong undertow are common on the Pacific side. Stick to protected, swimmable beaches Médano, Chileno, Santa María, Palmilla, and Acapulquito, and never enter the water without checking for a green safety flag. Warm water does not mean safe water.
