Headed to Cancun in October? You're in for a treat. Whether it's beach days, jungle adventures, or late-night dancing, this place knows how to deliver. But every month brings its own vibe, so a little planning goes a long way.
October sits right at the sweet spot of Cancun's calendar—warm Caribbean waters, fewer crowds than peak season, and that magical transition from rainy season to dry season. You'll catch the tail end of tropical showers (usually brief and refreshing) while enjoying plenty of sunshine and those perfect beach days that make Cancun legendary.
This guide gives you the lowdown on what to expect, what to bring, and how to make the most of your trip without overthinking your packing list. Consider it your cheat sheet for showing up ready for whatever Cancun throws your way.
What to Expect from October's Weather in Cancun
Average temperatures: Highs reach 87°F (31°C) during the day, cooling to comfortable 74°F (24°C) at night. You'll enjoy consistently warm tropical weather without the extreme heat of summer months—only about 7 days typically exceed 90°F compared to 17 in September.
Rainfall: October receives about 7 inches of rain over 7-11 rainy days, making it the second wettest month of the year. However, these are typically short, intense tropical downpours that clear quickly, often followed by brilliant sunshine. Rain usually hits in late afternoon or evening, rarely disrupting entire days.
Humidity: Expect high humidity ranging from 74% in the afternoon to 86% in the morning. The persistent moisture makes the "feels-like" temperature higher than actual readings, so lightweight, breathable fabrics are essential for comfort.
Sea temperature: The Caribbean maintains a warm 80–83°F (27–28°C)—ideal for swimming, snorkeling, and water sports. The warm waters feel refreshing against the humid air and provide instant relief from the heat.
Daylight hours: You'll enjoy 12 hours of daylight with about 7-8 hours of direct sunshine daily. The UV index remains very high, making sun protection crucial even on cloudy days.
