Humidity Levels: Comfortable Tropical Conditions

Kona experiences moderate humidity levels ranging from 50% to 70%. While the tropical environment can feel humid at times, the trade winds help to keep the air comfortable, especially during the summer months. These gentle winds also prevent the region from becoming too stifling, ensuring a pleasant experience throughout the year.

Trade Winds: Keeping the Heat at Bay

Kona benefits from the cooling effects of moderate trade winds that blow from the northeast. These winds help to moderate temperatures, providing relief from the heat, especially in the summer. The winds in Kona are generally less strong than on other parts of the island, making the area ideal for outdoor activities without feeling too hot.

Air Quality: Impact of Volcanic Activity

Due to its proximity to the active Kīlauea Volcano, Kona’s air quality can occasionally be affected by volcanic activity. Volcanic smog, known as vog, can occasionally drift over the island, especially during times of heightened activity at Kīlauea. Vog is a mixture of volcanic gases and ash that can reduce air quality, particularly for those with respiratory conditions.

As of January 2025, there is an Orange Volcano Watch in effect due to ongoing volcanic activity at Kīlauea. Visitors to Kona should stay informed about any changes in air quality and follow local advisories during such times.
