General Turtle Bay Resort Weather Information

The most prominent weather feature affecting Turtle Bay Resort is the persistent trade-wind flow that runs a general east-to-west direction throughout the year. The location and strength of these winds changes as the natural Pacific High moves north and south of the equator each year, bringing the heart of the trades to Turtle Bay Resort during the period from May through September, when the trades are prevalent 80 to 95 percent of the time. From October through April, the heart of the trades lies below Turtle Bay Resort so they are much weaker and only are felt 50 to 80 percent of the time.

The dominance of the trades and the influence of terrain give special character and stability to the climate of Turtle Bay Resort. Turtle Bay Resort is located on the boundary line between the windward and the north shore (more leeward) slopes of O’ahu. Dense cloud cover is typically confined to the mountain areas and windward slopes, while the leeward lowlands have only a few scattered clouds. As a result, completely cloudless skies are extremely rare but so are showers and when they come they are generally light and brief…just enough to keep things green and that’s it.

Even though Turtle Bay lies between the Equator and the Tropic of Cancer, the trades provide a marvelous system of natural ventilation, especially during the summer months when the sun is almost directly overhead, resulting in average daily high temperatures of 86 degrees during the summer months and 82 degrees during the winter months. Truth is, if Turtle Bay Resort’s only climate issues were the trade winds then the weather would be idyllically stable and nice, since average lows are 73 degrees during the summer months and 70 degrees during the winder months.

Unfortunately the trades, though dominant, are not the only major dynamic element. Hawaii sits in the middle of the largest ocean in the world. During an average year, three to seven major storm events will pass over Turtle Bay Resort, sometimes bringing heavy rains and strong winds. These major storms occur most frequently between October and March but can occur during anytime of the year.

True hurricanes are very rare in Hawaii. Tropical storms are also rare, but more frequent. Unlike the major storms that pass through more commonly during the winter months, hurricanes and tropical storms when they do happen are most likely to occur from July through December.

With that in mind, year round if you plan for high temperatures in the mid eighties and low temperatures in the seventies and if you plan for a mixture of sun and rain…you’ll be right on nearly all the time.
