Ko Olina Marina Forecast

Hawaii is often called one of the few places in the world with perfect weather and the saying among the residents when they read the temperatures during the winter on the mainland is always the same - "Lucky you live Hawaii." And so are our visitors to the islands who stay at Ko Olina Resort & Marina, as the leeward coast has some of the best weather on the island

There are basically only two seasons a year with winter (November to March) temperatures around 76 to 79 degrees during the day, often dropping 10-15 degrees at night. Summer (April to October) temperatures average 78 to 81 degrees, slightly cooler in the evening.

Water temperatures range from 74 degrees in the winter to 81 during the summer and rainfall is between 2 to 4 inches in the winter. The almost constant tradewinds play a large part in cooling off the summer temperatures, except when they slow down or disappear, making August and September our hottest months.
