September is a wonderful time for a Hawaii vacation with great weather, lower crowds and an abundance of natural beauty.
After Labor Day and with kids back in school in North America, the crowds are much lower. When crowds are down, hotel or vacation rental costs are lower than average, too.
What weather conditions to expect in Hawaii for a September vacation?
At most beach resorts, the daytime temperatures average in the mid-to-upper 80°F (31°C). Nighttime feels warm, too, with lows only dipping into the 70s.
On average, September is one of the drier months to visit Hawaii. So, you should be able to enjoy plenty of sunshine.
Ocean temperatures are at their warmest in September and October at approximately 81°F (27.2°C). While the water might feel chilly when you first dip your toes in, these ocean temperatures will feel pleasant after you acclimate.
There is one, weather “hitch” worth mentioning for a September trip to Hawaii. It’s hurricane season for the Pacific Ocean. The good news is that Hurricanes rarely make landfall in Hawaii, though the wind and heavy rain can affect the islands. (See frequently asked questions about Hawaii hurricanes.)
Another point worth mentioning is that after the drier months of summer, the waterfalls might not be as spectacular as they are in wetter seasons. With the rain starting to pick up a little bit, most waterfalls should be flowing.
