10-Day Weather Forecast for Kauai

Kauai weather 10 Day forecast and weather report for Lihue, Waimea, Princeville, North Shore. Kauai weather today forecast with satellite pictures, news, tsunami warnings.

The small, circular island of Kauai is formed by one eroded volcano, whose highest peak reaches 5,243 feet at Mount Wai'ale'ale near its center.This peak is regarded as the wettest, or second wettest place on the planet, with more than 460 inches of rain per year. The Kekaha coastal area, in its rain shadow only 20 miles southwest, averages less than a 20 inches per year. The spectacular Na Pali Coast, Princeville, and idyllic Hanalei, with their lush tropical environs on the north shore provide unparalleled opportunities for nature adventure. Poipu and Koloa on the drier, warmer south shore are the primary resort areas of Kauai.

Kauai has a spectacular, diverse climate and enjoys nearly perfect weather. Its daytime temperatures along the coasts generally range from only the mid-70s to the mid-80s most of the year. Kauai is the only state in the U.S. that has never recorded a sub-zero temperature.

Since Kauai has only two seasons-Summer (May through October) and Winter (November through April), you will experience more temperature variation between elevations and windward-leeward coasts, than you will between the seasons.

Kauai coastal temperatures can sometimes dip into the 60s during mid-winter and rise into to the 90s in mid-summer. Kauai's heaviest rains occur during winter-month storms, often riding Kona winds, which uncharacteristically blow from the southeast. Flash flooding is not uncommon at such times. Hurricane season in Kauai is June through November. Hurricanes are rare, occurring only about once every 10 years.

Kauai's Beneficial Geography

Located between 19 and 23 degrees north latitude, the inhabited Hawaiian Islands lie only 1,200 to 1,600 miles north of the equator. This fortuitous circumstance of geography means the sun is high in the sky year round, creating temperatures that warm both the land and the surrounding ocean, which varies in temperature from only about 75 degrees to 83 degrees between winter and summer.

Such a warm surrounding ocean keeps the atmosphere above the Hawaiian Islands relatively warm. But two other factors contribute to Kauai's reputation as a tropical paradise with diverse microclimates: Kauai's trade winds, and Kauai's numerous volcanic mountains.

Kauai Volcanic Mountains

The mountains of Kauai, formed millions of years ago though volcanic eruptions from the ocean floor - as the Pacific Plate moves slowly northwest over a hot spots in the earth's mantle - affect Kauai's climate and account for the variations in weather from both island to island and on the same Island.

Kauai Trade Winds

In Kauai, the northeast trade winds, averaging 12 mph, occur about 90% of the time in the summer and about 50% of the time in the winter. They keep humidity at a minimum and ensure moderate temperatures, especially on the windward, unlike other tropical islands closer to the equator.

These cooling winds are created because warm air rises near the equator, flows northward through the upper atmosphere, and cools. Because it becomes heavier as it cools, it falls back to the earth's surface at about 30 degrees latitude, where it flows back toward the equator to replace more rising warm air. This creates cool breezes moving from the northeast to the southwest along the ocean's surface, and over the Hawaiian Islands.
