Planning a trip to Puerto Vallarta in October puts you right at a seasonal crossroads. The rainy season is winding down, humidity is starting to ease, and the Sierra Madre mountains are at their greenest after months of summer storms.
This guide covers what to expect from Puerto Vallarta's weather in October so you can decide if the timing fits and plan accordingly.
What's the Average Temperature in Puerto Vallarta During October?
October delivers consistently warm days across Puerto Vallarta, with daytime highs landing between 89°F and 92°F and nighttime lows settling around 72°F to 76°F. Early October tends to run slightly warmer, while late October brings a gradual cooldown as the region transitions toward its dry season.
Either way, the temperatures hold steady enough that beach days, water activities, and outdoor adventures stay firmly on the table throughout the month.
How Hot Does It Get in Puerto Vallarta in October?
The thermometer tells only part of the story. With humidity levels ranging from 78% to 85%, the air feels heavier than the numbers suggest, especially between 1 PM and 6 PM when heat and moisture peak together.
The smartest approach is scheduling outdoor activities before 10 AM or after 6 PM and saving that midday window for the ocean, the pool, or somewhere with good air conditioning.
Is It Cold in Puerto Vallarta in October?
Cold weather simply isn't part of October in Puerto Vallarta. Even the coolest readings for the month rarely dip below 68°F, and persistent humidity makes the air feel warmer than actual temperatures indicate. You won't need jackets, sweaters, or anything heavier than a light layer for air-conditioned restaurants.
October here is tropical through and through, so pack accordingly and leave the cold-weather gear at home.
What's the Temperature Like at Night in Puerto Vallarta in October?
Evenings stay warm and comfortable, with temperatures easing from the mid-80s into the low-to-mid 70s after sunset. Early October nights hover near 76°F, while late October nights cool slightly to around 72°F as the season shifts.
High humidity keeps the air feeling mild even after dark, so evenings outdoors feel comfortable. The only layer worth packing is something light for restaurants that run the AC on full blast.
Is the Water Warm Enough to Swim in October?
October ranks among the warmest ocean months in Puerto Vallarta, with sea temperatures averaging 85–86°F and occasionally reaching near 90°F. At these temperatures, swimming feels immediately comfortable without any thermal protection.
Snorkelers can spend extended sessions in the water without getting cold, and divers will find that wetsuits are entirely optional for recreational depths. A thin 3mm suit might add comfort on multi-dive days, but most people won't need one. Underwater visibility is another highlight, reaching up to 130 feet at certain dive sites, which makes October one of the strongest months for anything below the surface.
Does It Rain in Puerto Vallarta in October?
Yes, it rains in October, but the pattern works in your favor. Showers typically arrive in brief evening bursts rather than all-day downpours, and most fall after dark. You can expect rain on roughly five to nine days throughout the month.
The key detail for planning: rainfall decreases rapidly as October progresses, so the second half of the month is noticeably drier than the first.
How Much Rain Should You Expect in Puerto Vallarta in October?
Total rainfall for October averages 3.7–5.2 inches across the entire month. That represents a dramatic 70–75% decrease from the peak months of August and September, when Puerto Vallarta sees 12 to 14 inches.
When rain does arrive, accumulation averages around 0.60 inches, classified as moderate rather than heavy. The typical shower rolls through quickly and clears out, leaving behind cooler air and often a spectacular sunset.
Is October Part of the Rainy Season in Puerto Vallarta?
October marks the final stretch of Puerto Vallarta's rainy season, which runs from mid-June through October. By the last week of the month, conditions closely resemble the dry season that officially begins in November.
This transitional position is actually part of October's appeal, as you get shoulder-season pricing and a more relaxed atmosphere while the weather is already shifting toward the drier, more comfortable months ahead.
Should You Worry About Storms in Puerto Vallarta in October?
October does carry tropical storm risk along Mexico's Pacific coast, and historical data shows the month has seen notable storm activity. Travel insurance that covers weather-related cancellations and delays is a smart investment for any October trip.
That said, major storms remain relatively infrequent events, and modern forecasting provides several days of advance warning. Monitor official weather channels in the days before your trip, keep your travel plans flexible where possible, and know that your accommodations will have established safety protocols in place.
Is It Windy in Puerto Vallarta in October?
Wind is barely a factor in October. Average speeds hold steady around 5.7 mph throughout the month, making it one of the calmest periods of the year. The gentle westerly breeze provides just enough natural cooling on the beach without kicking up sand or creating choppy water conditions.
For water activities, this translates to calm surface conditions that improve visibility for snorkeling tours and easy, stable conditions for swimmers.
What Wildlife Shows Up in Puerto Vallarta in October?
October is peak season for sea turtle releases. Olive Ridley and Pacific Green sea turtles nest along local beaches from August through December, and the majority of hatchlings emerge starting in October. Beyond the beaches, snorkelers encounter exceptional marine diversity at sites like Los Arcos, including angelfish, parrotfish, manta rays, and sea turtles in the water.
Birdwatchers will find lush, verdant landscapes filled with endemic species like the Golden-Cheeked Woodpecker and San Blas Jay. Humpback whales, however, typically arrive in December.
Does the Weather Affect Tours in Puerto Vallarta During October?
Tours run on full schedules throughout October, with our guides well-accustomed to the month's rain patterns. Since showers tend to arrive in the evening, most daytime excursions proceed without interruption.
When weather does shift during an activity, guides adjust timing and routes based on years of working in these conditions. Flexible cancellation policies are standard for October bookings, giving you added protection if a rare all-day storm appears on radar. Late October offers the most reliable conditions, so if your schedule allows flexibility, targeting the second half of the month reduces your chances of any weather-related changes.
What to Bring for Puerto Vallarta in October
A packable rain jacket tops the list since afternoon showers can catch you off guard. Bring two to three quick-dry swimsuits so you always have a dry option ready in the humidity. Sun-protective clothing, a wide-brimmed hat, and quality sunglasses handle the strong UV exposure.
Water-resistant sandals with good grip work for both town walking and beach hopping, and a pair of water shoes covers anything ocean-related. Bug spray and a light cardigan for overly air-conditioned restaurants round out the essentials.
Best Things to Do in Puerto Vallarta in October
October brings specific advantages to Puerto Vallarta. Sea turtle releases peak during this month, underwater visibility reaches its best levels of the year, and the Sierra Madre jungle is spectacularly green from months of summer rain.
