Quick Answer
December through April is Cancún’s prime window: reliable sunshine, dry air, and calm Caribbean seas. November and May work well as shoulder months with lower prices and still-good conditions. See everything Cancún offers before you book, and secure your accommodation early for any December to April visit.
Season Overview
Cancún has two clear seasons - dry (December–April) and wet/hurricane (June–October) - with May and November acting as transitional months.

Peak Season: December to April
This five-month stretch is when Cancún operates at maximum capacity. December delivers warm days (24–28°C), clear skies, and Christmas holiday energy - hotel rates in the Hotel Zone hit their highest point of the year in the week between Christmas and New Year, with some properties charging three to four times their off-season rates. January sees a slight crowd dip after the holidays before picking back up in February.
March and early April are Spring Break months. American university students arrive in very large numbers, and the Hotel Zone party scene operates at full intensity. Prices remain very high. If you prefer a calmer beach experience, target February or late April instead.
The sea is calm and clear throughout peak season. Visibility for snorkelling around Isla Mujeres and the MUSA underwater museum is typically 20–30 metres. Water temperatures range from 25°C in January to 28°C by April.
Shoulder Season: May and November
May offers excellent value for a Cancún trip. Hurricane season officially starts June 1 but rarely brings serious storms in May. Temperatures are warm (28–32°C), the sea is perfect, and hotel rates drop significantly from their March peaks. The beaches are far less crowded, and you can often access Isla Mujeres or Cozumel day trips without queuing.
November is increasingly popular as a shoulder month. The rains have stopped, temperatures sit around 25–29°C, and prices are still 20–30% below December rates. Día de los Muertos (November 1–2) sees local ceremonies in Cancún’s downtown (Centro) that are worth seeking out.
Off Season / Rainy Season: June to October
June through October is officially hurricane season, and Cancún sits squarely in the Atlantic hurricane belt. The risk is real but unevenly distributed: June and early July rarely see major storms, while August, September, and early October are statistically the most dangerous months. Hurricane Gilbert (1988) and Wilma (2005) both caused severe damage to Cancún’s Hotel Zone.
Even without hurricanes, this period brings daily rain, high humidity (85–95%), and heat that feels oppressive away from air conditioning. July is a partial exception - Mexican school holidays drive a domestic tourism surge, keeping hotels busier than June or September.

- November 1–2 - Día de los Muertos: Celebrations in Cancún’s downtown Centro district; less visible in the Hotel Zone.
