Where should you go in Nicaragua in september when it comes to the weather?
Remember:
The climate in Nicaragua in september ranges from tolerable to bad depending on the region and city.
That month is not the best month to travel to in Nicaragua. The weather in Bilwi, Ometepe Island, San Juan del Sur and Rivas is ok but correct. The sun is not there all the time and you might make you wet by rain frequently. Nonetheless, if you don't plan a beach and relaxation holiday in Nicaragua but rather nature excursions or a trek, this climate could be appropriate. In addition, there are definitely fewer tourists this month.
But it gets worse: in Siuna, Granada, Solentiname islands, Mombacho Volcano National Park, León, Matagalpa, Bluefields, Managua and Masaya and surrounding areas where the climate is even worse. It is really not advisable to travel to these areas in september.
