If you have been waiting for the right time to visit Cabo San Lucas, stop waiting. October and November might be the best-kept secret in all of Baja California Sur.

The summer crowds have thinned out. The water is still warm and crystal clear. Whale season is just getting started. And prices — for flights, hotels, and tours — are noticeably lower than peak winter rates. Fall in Cabo is genuinely special, and not enough people know about it.

Here is everything worth doing during these two incredible months.

Whale Watching Season Begins

This is the big one. Humpback whales begin arriving in the waters around Los Cabos in late October and November, migrating from their feeding grounds in Alaska and the Pacific Northwest down to the warm breeding waters of Baja.

Seeing a 40-ton humpback breach just a few hundred feet from your boat is one of those experiences that stays with you forever. Early season sightings tend to be especially exciting because the whales are active and energetic after their long migration.

Tours run daily from the Cabo San Lucas marina, and most operators offer a guarantee — if you don't see a whale, you go again for free. The season runs through March, but November departures often have smaller groups and more personal experiences than the packed January and February boats.

Snorkeling and Diving at Their Best

October and November offer some of the best underwater visibility of the entire year. The summer plankton blooms have settled, water temperatures are still a comfortable 78–82°F, and marine life is incredibly active.

Pelican Rock, Chileno Bay, and Santa Maria Bay are all outstanding snorkeling spots. For divers, Land's End and the Gordo Banks offer encounters with sea lions, manta rays, and the occasional whale shark.

The water won't feel this warm again until next summer — take full advantage of it.

Mobula Ray Season

October is peak season for mobula rays in the Sea of Cortez. These acrobatic rays — sometimes called "devil rays" — gather in massive schools and leap dramatically out of the water in a behavior scientists still don't fully understand.

Witnessing thousands of rays launching themselves into the air simultaneously is one of the most surreal wildlife experiences on the planet. Several local operators run dedicated mobula ray tours during this window, and it is absolutely worth adding to your itinerary.

ATV and Desert Adventures

The brutal summer heat is gone by October, making fall the ideal time for desert adventures. ATV rides, UTV off-road tours, camel rides, and horseback excursions through the Baja desert are all dramatically more enjoyable when temperatures are in the low 80s instead of the high 90s.

The desert landscape is also at its most dramatic in fall — the light is golden, the air is clear, and the contrast between the arid terrain and the deep blue Pacific is stunning.

Fishing for Marlin and Dorado

October is one of the best months of the year for sport fishing in Cabo. Marlin, dorado (mahi-mahi), wahoo, and yellowfin tuna are all running strong. The summer fishing season is winding down, which means the fish are feeding aggressively before the cooler winter months arrive.

If you have ever wanted to catch a marlin, this is your window. Charter boats fill up fast in October, so book early.

Day of the Dead Celebrations

One of the most meaningful cultural experiences you can have in Mexico falls right in this window. Día de los Muertos — Day of the Dead — is celebrated on November 1st and 2nd, and Los Cabos puts on a beautiful observance.

Altars (ofrendas) decorated with marigolds, candles, photos, and food appear throughout the region. Local markets fill with sugar skulls, pan de muerto (Day of the Dead bread), and traditional crafts. It is a celebration of life and memory, not a somber occasion, and visitors are warmly welcomed to observe and participate respectfully.

Explore San José del Cabo

The quieter, more colonial half of the Los Cabos corridor is at its best in fall. San José del Cabo's historic art district hosts gallery walks every Thursday evening, and the town's restaurants, boutiques, and coffee shops are far less crowded than in peak season.

The town's central plaza and mission church are beautiful in the softer fall light, and the local food scene — from street tacos to upscale Mexican cuisine — is genuinely outstanding.

Sunset Cruises and Party Boats

Cabo sunsets are legendary year-round, but fall evenings have a particular magic. The humidity drops, the sky turns shades of orange and pink over the Pacific, and the temperature on the water is absolutely perfect.

Sunset sailing cruises, catamaran party boats, and private yacht charters are all available daily from the marina. Many include open bar, live music, and snorkeling stops — making them one of the best value experiences in Cabo regardless of the season.

What to Expect Weather-Wise

October and November are transitional months in Cabo, and the weather is genuinely excellent.

October: Highs around 88–92°F, lows in the mid-70s. The tail end of hurricane season means there is a small chance of tropical weather in early October, but most years it is clear and sunny. Water temperature around 82°F.

November: Highs around 82–86°F, lows in the low 70s. Essentially zero chance of rain. This is arguably the most comfortable month of the entire year in Cabo. Water temperature around 78–80°F.

Both months offer far more comfortable conditions than the peak winter months of December through February, when temperatures can dip into the 60s at night.

Tips for Visiting in Fall

Book whale watching early. Even in the early season, popular operators sell out on weekends. Reserve your spot before you arrive.

Take advantage of lower prices. Hotel rates and tour prices in October and November are typically 20–40% lower than January and February. You get the same Cabo, for less.

Pack a light layer for evenings. November nights can be surprisingly cool, especially on the water. A light jacket or wrap is worth having.

Don't skip the Sea of Cortez side. The Pacific side gets all the attention, but the Sea of Cortez — with its calmer waters and incredible marine biodiversity — is especially magical in fall.
