Honolulu residents and visitors can expect changing weather in the coming days. Light to breezy winds will continue, thanks to high pressure northeast of the islands. A weak weather system west of Hawaii is bringing more showers, especially to the western islands and windward or mountain areas. If you're planning to be outside, be ready for some rain. Trade winds are expected to return by Tuesday evening, according to the National Weather Service in Honolulu.
Shower activity is expected to favor eastern exposures, as a statement by the National Weather Service Honolulu characterizes the steering flow as "dominant east southeast." With sea breezes in the afternoon, leeward regions could see increased showers. Greater rainfall could be in store for neighborhoods positioned downstream of each island's plumes formed by low-level convergent boundaries. These weather conditions are predicted to hold mostly steady throughout the week, with trade wind patterns continuing to govern shower distribution.
In aviation terms, moderate east-southeasterly winds are forecasted to persist throughout the rest of the day, with trade winds returning later tonight. Occasional showers may affect flight visibility, and AIRMET warnings are in place for mountain obscuration over parts of the islands and moderate turbulence. Pilots should be aware of these potential flight hazards and monitor updates closely, as reported by the National Weather Service.
The marine forecast foresees fresh east-southeast winds today due to the lingering upper low and surface trough. Boaters should exercise caution and heed the Small Craft Advisory in effect through late night Tuesday for several waterways around Maui and the Big Island. Although the northerly swell is subsiding, surfers can anticipate a consistent rise in east-facing shore surf through Wednesday, thanks to persistent trade winds boosting wave heights, as noted by the National Weather Service.
Later in the week, a weak upper-level trough may bring a slight increase in trade wind showers over Hawaii. Surf conditions will vary, with northwest swells fading and new south-southwest swells on the way. The National Weather Service says those on southern shores should expect above-average surf, especially over the weekend.
