Mexico's Weather Forecast and Climate
Mexico weather is difficult to predict as typical weather patterns within the country vary significantly from region to region. The winter months extend from November to May and the summer months run from June to October. On the whole the climate is relatively mild, making it possible to visit the country at any time during the year.
Mexico's climate mimics its countryside in the sense that it changes so dramatically from area to area. When traveling from the coastal regions to the mountainous inland areas you will find it hard to believe that you are still in the same country. In summer, inland areas such as San Cristobal seldom get hotter than 72 degrees Fahrenheit, while in coastal regions such as Acapulco and Merida thermometer readings often top 92 degrees Fahrenheit.
As winter approaches, coastal areas become dryer and humidity and temperature levels decrease. Average temperatures seldom dip below the 65 degree mark, meaning that it is possible to still get a decent tan even in mid February. By contrast, you'll need to wrap up warmly in the mountainous regions where minimum temperatures drop as low as 40 degrees in some parts.
Mexico's rainy season falls during the summer months, and precipitation varies from place to place within the country. The northern areas are usually dryer, while inland and further south rainy spells occur far more frequently. During the late summer months inland roads are often washed away by torrents of water, so if you are planning a road trip make sure you consult news and weather reports first.
While it is possible to visit Mexico any time during the year, certain months are undoubtedly better than others. Extreme heat and humidity make the low-lying coastal regions almost unbearable from June to October. Tropical storms and hurricanes are also known to hit the coastal areas during this period making recreational activities such as sailing impossible. For this reason its better to stick to the more temperate highland areas during the summer months and save tropical coastal resorts such as La Paz and Acapulco for winter months when it is cooler.
November is seen as one of the best months to visit coastal areas as temperatures are mild and prices are reasonable. The only exception to this rule is diving vacations which are best left until March or April. The reason for this lies in the fact that top diving areas such as Cozumel and Cancun have a second rainy season from November to January. This often results in unfavourable conditions and poor visibility and in many cases renders boat launches totally impossible.
