A: Expect a mild tropical climate all year long, with two seasons, winter (rainy) and summer (dry). Summers average between 85-90 °F (29-32 °C), while winters are between a balmy 79-83 °F (26-28 °C). In higher elevations, such as Waimea, temperatures are often lower, especially at night. Hilo can also be cooler, depending on your inland location, and Mauna Loa & Mauna Kea can be quite chilly, so pack accordingly. The Big Island receives most of its rainfall from the end of November through the beginning of March. The East side of the Big Island is the one that gets most of the rain, and Hilo is America's wettest city; it receives up to 160 inches of rain each year. The weather in Kailua-Kona and the rest of the Big Island's Northwestern coastal area is consistent, which is one of the reasons it's a popular vacation destination. Our resort's location is one of the least rained-upon parts of the Big Island, with mean annual rainfall on the Kailua-Kona coast averaging a mere 22 inches (although the amount increases as you move further up the slope of Mt. Hualalai). This is what makes Kailua-Kona one of the Big Island's "sweet spots" regarding weather.
