The temperature of the water around the Hawaiian islands doesn’t fluctuate very much between the summer and winter months. The National Oceanographic Data Center records water temperatures around the islands every day. Their monitoring station in Honolulu reports the following temperatures for the year:

Hawaii Water Temperatures

Beaches with mostly shallow water will have slightly warmer temperatures. In the winter the water may feel cool for people who lack “insulation”, especially on a cloudy day when the winds pick up. If you plan on doing a lot of snorkeling, investing in a wetsuit top is recommended. They cost about $75, but wait until you get to Hawaii to make the decision on whether you’ll need one.
