Weather at Mexico Beaches: Annual Averages

This page pulls together weather information for popular resort beaches in Mexico.

You can compare yearly averages for temperature, total rainfall and ocean temperature at vacation spots along the Pacific Ocean and the Caribbean Sea.

The temperatures here are in degrees Fahrenheit and Celsius. Total rainfall is given in days, inches and millimetres.

Among Mexico's major beach destinations, the hottest during the day on average are Zihuatanejo and Huatulco, while the warmest nights happen at Acapulco. The lowest daytime temperatures normally occur in Mazatlán, while the coolest nights are at Cabo San Lucas.

Cancun and Cozumel on the Yucatan Peninsula get rain far more often than any of the Pacific beaches. But the total amount of annual rainfall at the Caribbean beaches is similar to what falls at many places on the west coast. The driest beach of all borders the desert at Cabo San Lucas.

Place name links take you to more detailed weather information for that location.
