Honolulu, Hawaii – A wetter weather pattern is expected to bring increased rainfall across Hawaii heading into mid-January, with periods of rain likely for most islands, including the Big Island.
According to the National Weather Service Climate Prediction Center, Hawaii is favored to see above-normal precipitation during the January 9–13 period, while temperatures trend near seasonal averages. This setup supports more frequent showers, especially as trade winds strengthen and weather disturbances pass through the region.
Windward and mauka areas across Oahu, Maui, Kauai, and the Big Island are most likely to see steadier rainfall, with passing showers at times spreading into leeward communities. On the Big Island, heavier rain is possible along the east-facing slopes and higher terrain, including areas near Hilo and the Hamakua Coast.
Travel impacts may include wet roads, reduced visibility during heavier showers, and localized ponding in low-lying or poor drainage areas. Mountain roads on the Big Island and Maui could see periods of low clouds and fog during rainfall.
Residents and visitors are encouraged to remain aware of changing conditions and allow extra travel time during periods of rain. Additional advisories or flood statements may be issued closer to mid-January if rainfall becomes more persistent or intensifies across any of the islands.
