Other months in San Pedro
San Pedro's forum says October weather can be genuinely nice, with wind being the bigger day-to-day factor than rain itself - a typical day still runs sunny, hot and humid. When rain does show up it's usually overnight or a brief afternoon shower, rarely an all-day downpour, and posters were consistent it rarely derails plans. October is technically the tail end of hurricane season, but actual hurricanes hit only about once every five years on average, and several locals specifically recommended the month for the slow-season deals and quieter island.
