Acapulco Monthly Weather Averages: Rain, Temperatures

Acapulco monthly weather has temperatures ranging from the low 80s Fahrenheit in the winter to the low 90s in the summer. Rainfall ranges from nearly zero during the dry season to 15 inches in the rainy season.

Cruise and resort visitors go to this popular city on the west coast of Mexico to take advantage of the warmth.

The weather is often separated into two categories: the dry season and the rainy season. The dry season attracts more tourists because there are more sunny days during this time.

The dry season brings warm days and comfortable nights. It runs from November through May, with an average daily temperature in the upper 80s Fahrenheit. There are few days of rain, and the humidity is also low.

The rainy season is from June to October. Rainfall and temperatures both rise. The daily average temperatures run in the 90s, and humidity increases as well. With the increase in rainfall, the tropical forests become lush and green.

Many local businesses and tour companies shut down during the rainy season. But hotel and restaurant prices drop, which means some great deals for cruise and resort visitors.
