Where should you go in Micronesia in september when it comes to the weather?
Remember:
The climate in Micronesia in september ranges from good to very bad depending on the region and city.
That month is not the best month to go to in Micronesia. The weather in Caroline islands is ok but correct. The sun is not there all the time and you risk you to be soaked by rain frequently. Nonetheless, if you don't plan a pool and sun travel in Micronesia but rather nature excursions or a trek, this climate may suit. In addition, there are certainly fewer tourists this month.
But it is finally better than in Marianas and Marshall islands and surrounding areas where the climate is even worse. We really do not recommend you to travel to these areas this month.
