You could have bad weather anywhere you go but to predict it 3 months in advance won't work. We have gone at times that are not considered in the "rainy season" and got quite wet and, on the other side we have gone in September which is hurricane season and had great weather.

Do your homework and maybe look at historical weather and go with that but even then it could be totally different...and, as mentioned, remember the time difference as you posted around 4am USA time and I doubt too many were online then
