What October feels like
October sends the Ironman noise to the other side of the island and almost none of it here. It's a good month for Volcanoes National Park — cooler up at that elevation, and the rainforest stretch past the lava tube is at its most dramatic when it's wet.
This is the wet season: rain on about 17 days, so pack accordingly. It’s sticky — light fabrics and an afternoon break earn their keep.
Can you swim?
The ocean runs about 81° — bath-warm.
