Cabo San Lucas sits at the southern tip of Baja California, where the Pacific Ocean meets the Sea of Cortez. That geography gives it a unique climate — and it means the "best" time to visit depends entirely on what you want to do.

Here is the honest, month-by-month breakdown from people who live and work here.

The Short Answer

November through May is peak season for a reason: warm days, cool nights, calm seas, and zero chance of a hurricane. If you want the most comfortable, activity-packed trip, aim for this window.

June through October is the off-season — hotter, more humid, and technically hurricane season. But it also means lower prices, fewer crowds, and some of the best fishing of the year.

Month-by-Month Breakdown

November – February: Peak Season

This is Cabo at its finest. Temperatures hover between 70–80°F (21–27°C) during the day, dropping to a pleasant 60s at night. The Sea of Cortez is calm and clear, making it ideal for snorkeling, sailing, and water sports.

The big bonus: Humpback whales arrive in Cabo's waters from December through April. If whale watching is on your list, this is your window.

The catch: This is also the busiest and most expensive time to visit. Book tours and accommodations well in advance, especially around Christmas, New Year's, and spring break (March–April).

March – April: Spring Break & Whale Season

March and April bring a surge of visitors — college spring breakers, families, and couples all converge on Cabo. The weather is spectacular: sunny, warm, and breezy. Whale watching is still excellent through April.

If you can visit in early March before the spring break rush, you will get near-perfect conditions with slightly smaller crowds.

May: The Sweet Spot

May is arguably the most underrated month to visit Cabo. The spring break crowds have gone home, prices drop noticeably, and the weather is still gorgeous — warm but not yet oppressively hot. The Sea of Cortez is crystal clear.

Whale season is winding down, but fishing picks up significantly. If you want great weather, lower prices, and fewer tourists, May is your month.

June – September: Summer Heat & Hurricane Season

Summer in Cabo is hot and humid. Daytime temperatures regularly hit 95–100°F (35–38°C), and the humidity makes it feel even warmer. The Sea of Cortez warms up to bathtub temperatures, which is actually great for swimming.

Cabo is technically in the hurricane zone from June through October, though direct hits are rare. More common are tropical storms that bring brief but intense rain and rough seas. Some tours may be cancelled during these periods.

Why come in summer? Prices drop 20–40% on hotels and tours. Crowds thin out dramatically. And the fishing — particularly for dorado (mahi-mahi), yellowfin tuna, and wahoo — is exceptional.

October: Transition Month

October is a mixed bag. Early October can still see tropical weather, but by mid-to-late October the humidity breaks and temperatures become very comfortable. It is one of the best months for fishing, and prices are still lower than peak season.

If you are flexible, late October is a fantastic time to visit — you get the tail end of off-season prices with the beginning of peak-season weather.

What to Do in Each Season

Best for Whale Watching

December through April. Humpback whales migrate to the warm waters of the Sea of Cortez to breed and give birth. January and February are the peak months, when sightings are nearly guaranteed.

Best for Fishing

Year-round, but summer and fall are exceptional. Cabo is known as the "Marlin Capital of the World," and striped marlin are present almost every month. Dorado, tuna, and wahoo peak from June through November.

Best for Snorkeling and Diving

November through May. Calmer seas and better visibility make for the best underwater experiences. The water is still warm enough to be comfortable without a wetsuit.

Best for Deals

June through October. You can find hotel rates 30–40% lower than peak season, and tour operators often run promotions to fill boats.

What About Crowds?

The busiest periods are:

• Christmas and New Year's (book 3–6 months in advance)
• Spring Break (mid-March through early April)
• Thanksgiving week
• U.S. holiday weekends

If you want a more relaxed experience, aim for early December, January (after New Year's), or May.

Packing Tips by Season

November–April: Light layers for evenings, sunscreen, hat, and a light jacket for boat tours. The sea breeze can be cool.

May–October: Breathable, lightweight clothing. Reef-safe sunscreen is a must. Bring a rain layer if visiting June–September.

Year-round: Water shoes or sandals, a reusable water bottle, and motion sickness medication if you are prone to seasickness on boat tours.

The Bottom Line

There is no bad time to visit Cabo — just different trade-offs. If budget is your priority, go in summer. If you want the best weather and whale watching, go November through April. If you want the sweet spot of great conditions and manageable crowds, aim for May or late October.

Whatever month you choose, book your tours in advance. The best experiences — private fishing charters, whale watching boats, and snorkeling tours — fill up fast, especially during peak season.
