Climate

Kauai is a Hawaiian island of seven micro climates ranging from dry desert to tropical rain forest. Poipu Beach has a semi-arid tropical climate. The near-by Haupu Mountain range blocks most prevailing showers. The average annual rainfall in Poipu is 34 inches. By comparison, Miami receives 55 inches. In the winter, daytime temperatures in Poipu range from the mid 70's to the lower 80's. Nighttime temperatures are in the low to mid 60's. In the summer, daytime temperatures go as high as the upper 80's, and during the night, down into the low 70's. When showers make it into the Poipu area, they are usually brief. We always recommend wearing natural fiber clothing such as cotton which is most comfortable in the tropics. We also recommend packing a sweater or jacket and long pants to take on trips up into the mountains, where the air, at 4,000 feet, is cooler. Most of the Poipu area hotels do have air conditioning. Many other types of accommodations do not, but are equipped with ceiling fans and louvered windows. Our prevailing trade winds provide a natural cooling effect most of the time.
