What is the Average Temperature in Hawaii?
Hawaii is an amazing U.S. state located on the archipelago of the Pacific Ocean. It has an exotic climate, with distinct wet and dry seasons that make the most of the year a pleasant time to visit. In this guide, we’ll provide you with an insight into the answer to the question “What is the average temperature in Hawaii?”
Hawaii features multiple climate zones, but the majority of it experiences a tropical climate all year round, with temperatures hovering around 70-85° Fahrenheit (21-29° Celcius). This mean temperature stays reasonably steady season-to-season, with some variations among its various regions.
To break it down a little further, here are the averages across different regions of Hawaii:
| Area | Average Temperature (°F) |
|---|---|
| Maui | 77-82 |
| Kauai | 77-82 |
| Oahu | 77-82 |
| Hawaii (the Big Island) | 73-80 |
The warmest months in Hawaii tend to be August and September, when temperatures peak and average in the mid-80s (29° Celsius). The driest months are July and August, when rainfall is at its lowest. The months of September and October are usually the wettest, with large amounts of rain coming in along with the seasonal storms like Kona storms, caused by eastward moving tropical systems.
During winter, the temperatures tend to drop a bit, and the higher elevations in Hawaii (such as Mauna Kea and Haleakala) get cooler temperatures, usually in the mid-60s (15° Celsius). A polar air mass might occasionally make its way south from Alaska, but these icy interlopers never manage to stay longer than a few days. The typical winter temperatures still remain warmer than most continental U.S. states.
Taking all these factors into consideration, you can see that the average temperature for the entire state of Hawaii remains relatively consistent throughout the year, staying in the 77-81° Fahrenheit (25-27° Celsius) range for much of the time.

The average temperature throughout the year typically ranges between 77-81° Fahrenheit (25-27° Celsius).
