Can't speak for the rest of the country but , from what i Understand, where you are going isn't prone to earthquakes. As for the weather, I don't know much but seems like is coming to the last month of the wet season - so probably be short but heavy rainfall at times, but this will clear the air....I`m discussing the probability of more earthquakes in Mexico my friend.This will be our first time there and seriously looking forward to some,sea,sand,beers and snorkelling.
I noticed from the weather reports for Puerto Aventuras for the next 10 days, that its sunny but everyday has thunderstorms,so do I assume that we`re not coming into the best time of the year for continual sunbathing. ;)
