Planning a trip to Cabo San Lucas in October puts you right in the middle of a seasonal shift. The summer heat starts loosening its grip, humidity drops week by week, and the ocean stays warm enough to spend hours in the water without thinking twice. It's a month that rewards travelers who know what to expect.
This guide breaks down exactly what to expect from Cabo's weather in October. We'll cover temperatures, rain patterns, ocean conditions, and how all of it affects your plans. Everything you need to decide is here. By the end, you'll know if October fits what you're looking for and how to make the most of it.
What's the Average Temperature in Cabo San Lucas During October?
October delivers consistent warmth across the entire month, with average highs of 88–91°F (31–33°C) and average lows between 69–78°F (21–26°C). Early October starts with highs around 86°F and lows near 78°F, but by the final week, temperatures ease down to about 84°F for highs and 75°F for lows.
Combined with falling humidity, that shift makes late October feel noticeably more comfortable.
How Hot Does It Get in Cabo San Lucas in October?
Peak heat hours hit between 10 AM and 3 PM, when temperatures push toward 91°F in direct sunlight. October's humidity ranges from 71% to 76%, which makes the air feel warmer than the actual reading, especially early in the month. By mid-to-late October, humidity dips to around 71%, and that sticky edge fades. The cooler hours for physical activity are before 9 AM and after 4 PM.
Is It Cold in Cabo San Lucas in October?
Cold weather isn't part of October in Cabo. Even at its coolest, nighttime lows range from the upper 60s to upper 70s°F, and daytime temperatures consistently reach the upper 80s to low 90s°F.
While historical records show a record low of 55°F, that's a rare outlier rather than something to plan around. The month sits squarely in warm-to-hot territory from sunrise to well past midnight.
What's the Temperature Like at Night in Cabo San Lucas in October?
Evenings stay warm throughout October, settling into the low-to-mid 70s°F after sunset and holding there through the night. Early in the month, expect lows closer to 78°F, while late October nights cool to around 75°F.
Lightweight clothing works for everything from waterfront dinners to late-night walks along the Marina district.
Is the Water Warm Enough to Swim in October?
October's ocean temperatures rank among the warmest of the year, averaging 84°F (28.9°C) in the Sea of Cortez with a range of 82–86°F throughout the month. That warmth means swimming, snorkeling, and diving all feel comfortable without a wetsuit. Most swimmers and divers are comfortable in a rash guard and shorts, though a thin 3mm wetsuit is an option for extra warmth at depth.
Underwater visibility is another October highlight, often exceeding 100 feet, which creates exceptional conditions for spotting marine life. One important distinction: the Sea of Cortez side offers safe swimming conditions, while the Pacific Ocean side carries strong currents and is not safe for swimming regardless of water temperature.
Does It Rain in Cabo San Lucas in October?
October brings very little rain to Cabo. Expect only one to two rainy days across the entire month. That's a sharp drop from September, which averages more than double the rainfall.
When showers do appear in October, they tend to be brief afternoon events rather than all-day downpours, so they rarely disrupt plans for more than an hour or two.
How Much Rain Should You Expect in Cabo San Lucas in October?
Typical October rainfall totals are 30–35mm (about 1.2–1.4 inches), which represents about 10.6% of Cabo's total annual rainfall of 284mm.
Year-to-year variability can range from virtually no rain to higher totals if a tropical system passes through, but on average, October is one of the driest months within the rainy season calendar.
Is October Part of the Rainy Season in Cabo San Lucas?
Technically, yes. Cabo's rainy period runs from roughly early July through mid-January, but October sits at the tail end of meaningful rainfall. October marks the sharp transition between summer monsoon influence and the bone-dry winter months ahead.
By November, rainfall drops to just 10mm. So while October still carries the "rainy season" label, the actual conditions feel much closer to the dry season that follows.
Should You Worry About Storms in Cabo San Lucas in October?
October falls within the Eastern Pacific hurricane season, which runs from May 15 through November 30, and tropical storm activity remains elevated through the month. Hurricane Norma (Category 4, 2023) is a recent example.
Modern forecasting provides two to five days of advance warning before a storm arrives, giving travelers time to adjust plans. Comprehensive travel insurance covering weather disruptions is worth purchasing for October travel, and monitoring NHC updates keeps you informed.
Is It Windy in Cabo San Lucas in October?
Wind stays remarkably calm throughout October, with average speeds around 7–8 mph from the west. For beach days, it means comfortable conditions without sand blowing around.
For water activities, it translates to minimal wave action, reduced seasickness concerns on boat tours, and reliable access to snorkeling spots. Speeds stay remarkably consistent day to day, making October ideal for planning anything on the water.
What Wildlife Shows Up in Cabo San Lucas in October?
October brings strong wildlife viewing, though what you'll see differs from the winter months. Sea lion colonies are fully active, with playful pups from the recent breeding season making underwater encounters especially entertaining.
Sea turtles are in peak nesting season with five endangered species active along Baja's coastline between August and December. Beneath the surface, tropical fish and eagle rays are common sightings in the warm, clear water. Manta rays and hammerhead sharks appear at deeper sites. One key expectation to set: humpback whales haven't arrived yet and won't appear until mid-November, so whale watching isn't an October activity.
Does the Weather Affect Tours in Cabo San Lucas During October?
Most outdoor tours run smoothly in October thanks to calm seas, warm temperatures, and minimal rainfall. Water-based tours carry the highest potential for weather-related changes, primarily if a tropical system develops and creates rough sea conditions near exposed areas like Land's End.
When that happens, tours may adjust routes to more protected waters, modify departure times, or reschedule entirely with full refunds. Booking tours with flexible cancellation windows and scheduling water activities for morning departures, when seas tend to be calmest, gives you the best odds of smooth sailing.
What to Bring for Cabo San Lucas in October
October's conditions in Cabo mean you'll want specific gear to stay comfortable and make the most of your trip. Breathable fabrics like cotton and linen handle the heat and humidity, while a rash guard pulls double duty for sun protection during water activities.
A lightweight rain jacket covers the small chance of afternoon showers. Wide-brimmed hats, quality sunglasses, and sun-protective clothing matter more than you might expect with October's high UV index.
