weather in kauai in october
Kauai in October. Kauai in October. The temperatures are dropping, the leaves are turning and the days are getting shorter. It feels like fall. Not on Kauai. Right now, the temperatures are mild, just a few degrees shy of the summer heat. The skies are clear and the ocean conditions outstanding due to temporary pauses in trade-wind activity. All the kids are back to school, so the beaches are empty, but the water is still warm enough for swimming.
