Climate Overview
Cancun enjoys a tropical climate year-round, with warm temperatures consistently between 75°F and 90°F (24–32°C). The region experiences two main seasons: the dry season from November to April, and the wet season from May to October. Humidity is high throughout the year, typically ranging from 70–80%, so light, breathable clothing is essential. The Caribbean Sea stays warm enough for swimming year-round, averaging 78°F (26°C) in winter and 84°F (29°C) in summer.
Best Time to Visit
The ideal window is November through April, when rainfall is minimal, humidity drops slightly, and temperatures are most comfortable for outdoor activities. December to February represents peak season—expect higher hotel rates (often $150–300+ per night for mid-range options) and crowded beaches, particularly around Playa Delfines and Puerto Morelos. If you prefer fewer tourists and better deals, visit May or September, when rates drop to $80–150 nightly, though afternoon thunderstorms are common.
Seasonal Breakdown
Hurricane season runs June through November, with September and October carrying the highest risk. While Cancun's infrastructure handles storms well, this uncertainty affects travel plans. Summer (June–August) brings intense heat and humidity above 85%, making daytime exploration challenging. Spring and early fall offer sweet spots: March–April and October–November feature manageable crowds, lower prices, and mostly favorable weather. Plan indoor activities like visiting the Mayan ruins at Tulum or exploring Cancun's museums for afternoon downpours during wet months.
