puerto rico: I'm visiting Puerto Rico (San Juan, Vieques) the last two weeks of September this year. Wondering what the weather is usually like around this time, and any predictions for this year?|||If you are scare of flying not a good time a rough flight is expected at this time of year. The weather in Puerto Rico is great at this time of year.|||September is the peak of the hurricane season. So basically you will expect lots of rain, hopefully not a hurricane or storm. Also, weather in the northern part of the island is a lot more humid and rainy than the southern part. The southern region also tends to be hotter, about 90-100°F, and it's not as rainy and humid as the rest of the island.|||September is at the peak of the storm / hurracaine season. We had just experience the pass of "Earl" near our island, it was just much rain and windy, but not much. Other tropical storms may visit or pass by Puerto Rico during September. Verify NOAA or other weather websites for actual information. http://www.srh.noaa.gov/sju/|||Hot, sunny, about 85 to 93 degrees daytime, about 75's on night. September is the peak season for Tropical storms and Hurricanes on the Caribbean, but hopefully, like last 10 years, they will not have direct hit on the Island.|||I live in Puerto Rico, and its usually like this: Chilly in the Mornings, humid and hot in mid-day, and a little bit of both in the night.|||It will probably hot, humid and watch out with the storms, but you definitely love it anyways. Hope u have fun!|||freaking hot
