The hottest month is May, averaging 91f high temperatures, with January being the coolest, averaging 63f
low temperatures. Generally the swing between high and low is 8-14 degrees, although an incoming north
wind can change that by more than 15 degrees within minutes.

Rainfall is highly variable because of terrain features.  Within a mile, rain total may differ 200%.

The wet season extends from mid June to December, with most rain occurring June to October.
Fairly dry months are expected January through May, with April & May the driest.

Windy season runs September to May, when North winds
(nortes) can occasionally gust to 60 miles/hour,
interchanging with
suradas, (South winds), occasionally gusting at equal speeds from February to May.

Brushes with hurricanes or tropical storms are a rarity. The first hurricane to affect Los Tuxtlas in 36 years
made land fall near the Catemaco coast in October 2005. The last volcano erupted in 1793.

So when is a good time to visit?
Anytime! The weather is rarely nasty more than a few days.
