Acapulco weather is almost always sunny, hot and humid. I was tempted to put a banner from the Weather Channel on this page, but their online forecasts of the Acapulco weather are completely useless and inaccurate. Every time they forecast 5-7 degrees LOW and call for rain on every single day of the "rainy season". This page has all you really need to know about the weather for your trip, including what clothes you should pack for the city's tropical climate.
