Climate - Acapulco (Guerrero)

The climate of Acapulco is tropical, hot all year round, with a dry, less hot period from December to April and a muggy, rainy period from June to October.
Acapulco de Juárez is located on the southern coast of Mexico, in the state of Guerrero.
Due to the low latitude (we are at the 16th parallel) and to the presence of the mountains to the north, which protect it from cold winds, the city is hot and sunny even in the middle of winter. However, from December to April, the temperature can drop below 20 °C (68 °F) at night. On the other hand, during the day the temperature can reach 35 °C (95 °F) all year round.
From June to November (but with a higher probability from August to October), there is the risk of hurricanes of the Pacific Ocean. For example, the city was hit by Hurricane Manuel in September 2013, and by Hurricane Pauline in early October 1997.

Best Time

Acapulco can be visited from December to April, as it is a dry period and outside the hurricane season.
