Planning a trip and wondering about the Cabo San Lucas weather in October? You’re looking at the ultimate transition month. The aggressive late-summer heat finally breaks, yet the ocean stays bathwater-warm. Expect average daytime highs around 88°F (31°C) and water temperatures peaking at 84°F (29°C).
It’s the absolute best time for snorkeling, diving, and yachting before the massive winter crowds arrive. While the tail end of hurricane season still officially lingers, widespread rain is rare. If you want peak ocean conditions without paying peak-season premium rates, Cabo in October hits the absolute sweet spot.
What is the Weather Like in Cabo in October?
Cabo weather in October features average daytime highs of 88°F (31°C) and nighttime lows around 70°F (21°C). The oppressive humidity drops significantly compared to late summer. Water temperatures reach their annual peak at 84°F (29°C), offering ideal, warm conditions for swimming, snorkeling, and diving in the Sea of Cortez.
Average Temperatures & Humidity
October acts as the bridge between the sweltering heat of August and the cooler, breezy days of December. When you step off the plane at Los Cabos International Airport, you’ll still feel the heat. However, it lacks the heavy, suffocating humidity of the prior months.
Mornings start crisp and clear. By mid-day, you’ll want a cold drink in your hand and a shady spot on a boat deck. The evenings cool down beautifully. You can finally enjoy al fresco dining in the marina without breaking a sweat.
We consistently notice our guests spending longer hours out on the water during this month. The sun feels less punishing. The breeze feels incredibly refreshing.
Water Temperatures
If you take only one piece of information away from this guide, let it be this: October offers the warmest water of the entire year.
The Sea of Cortez absorbs the intense summer heat for months. By October, it releases it slowly. You are looking at ocean temperatures hovering between 82°F and 84°F. You won’t need a wetsuit. You won’t hesitate before jumping in.
According to marine data from the National Oceanic and Atmospheric Administration (NOAA), these conditions create a thriving, active marine environment. Tropical fish are everywhere. The visibility often stretches beyond 80 feet. For water sports enthusiasts, the conditions literally do not get better than this.
Is October Still Hurricane Season in Los Cabos?
Yes, October officially falls within the Pacific hurricane season, which runs until November 30. However, the highest risk for severe storms in Cabo San Lucas occurs in September. By mid-to-late October, the threat drops drastically. Most days are sunny, and Cabo averages only one or two rainy days the entire month.
Rainfall Expectations
Tourists often panic when they hear the words “hurricane season.” Let’s look at the reality on the ground.
Most Pacific storms form much further south off the coast of mainland Mexico. By the time they push north toward the Baja Peninsula in October, they usually sheer apart or curve out into the open Pacific Ocean. You can track this historical storm behavior through the National Hurricane Center (NHC).
Does it rain? Sometimes. But when it does, it’s rarely a multi-day washout. You might experience a fast, dramatic afternoon thunderstorm. The sky turns dark, it pours for an hour, and then the sun comes right back out.
Don’t let the technical end of hurricane season scare you away. You’re far more likely to experience seven straight days of flawless sunshine than a trip-ruining storm.
Best Things to Do in Cabo San Lucas in October
The best things to do in Cabo San Lucas in October revolve around the exceptionally warm ocean. Top activities include snorkeling at Santa Maria Bay, competing in or watching the famous Bisbee’s sportfishing tournaments, taking sunset yacht cruises, and exploring the iconic El Arco without the heavy winter boat traffic.
Snorkeling at El Arco and Santa Maria Bay
With water temperatures hitting 84°F, staying on land is a mistake. You need to get out to the reefs.
Santa Maria Bay and Chileno Bay offer world-class visibility in October. You’ll swim alongside massive schools of Sergeant Majors, pufferfish, and maybe even a passing sea turtle. The sheer amount of life beneath the surface is staggering.
Of course, no trip is complete without visiting the famous Arch (El Arco). Instead of crowding onto a packed public water taxi, we highly recommend booking a private yacht cruise to El Arco. You get the freedom to snorkel at your own pace, blast your own playlist, and enjoy cold drinks prepared just for you.
Experience a Sea of Cortez Sunset
October delivers the most dramatic sunsets in Baja California Sur.
During the winter, the sky is often a flat, cloudless blue. In October, lingering moisture in the atmosphere creates high-altitude cloud formations. When the sun dips below the Pacific, those clouds catch the light. The sky explodes in violent shades of magenta, gold, and deep purple.
You haven’t really seen a Cabo sunset until you’ve watched it from the deck of a boat. There’s nothing quite like enjoying a private catamaran sunset tour with an open bar, zero crowds, and the sound of the hull cutting through the water.
Sportfishing and Local Tournaments
October is the Super Bowl of sportfishing in Los Cabos.
This is the month of the world-famous Black & Blue Tournament. Anglers from all over the globe descend on the marina to hunt for massive marlin. The energy in town is electric. You can walk the docks in the afternoon to watch the massive catches being weighed in. You can learn more about the staggering multi-million dollar payouts at the official Bisbee’s website.
Even if you aren’t a pro angler, chartering a boat for a half-day of fishing in October is a thrilling experience. The waters are teeming with Dorado (Mahi-Mahi), Yellowfin Tuna, and Wahoo.

What to Pack for an October Trip to Cabo
Packing for October requires a bit of strategy. You need to prepare for hot afternoons, breezy evenings, and plenty of time in the water.
- Reef-Safe Sunscreen: The Mexican sun is intense, and the glare off the water multiplies the effect. Protect your skin and the coral reefs by bringing biodegradable SPF.
- Light Layers: Bring a light windbreaker or a long-sleeve linen shirt. You’ll want it for those sunset boat rides when the ocean breeze picks up.
- Polarized Sunglasses: Don’t skip the polarization. It cuts the glare off the ocean surface, allowing you to actually see the fish and marine life swimming around the boat.
- Multiple Swimsuits: You will practically live in them. Bring at least two so you always have a dry one ready to go.
- Waterproof Phone Case: When the yacht pulls up to El Arco, you’ll want to lean over the rail for photos. Secure your phone.
