Trade winds are blowing across Oahu today but will start easing tomorrow. The National Weather Service expects showers mainly in windward areas as these winds continue. Later this week, fewer windward showers will occur, though afternoon rain might develop in interior areas.
A high-pressure system northeast of Hawaii currently maintains these strong winds. The weather pattern includes a weak upper-level low adding some instability, which brings brief heavy showers to certain spots. These scattered showers will focus on windward slopes through tonight. Pilots should watch for moderate turbulence below 8,000 feet over the leeward parts of the islands until evening.
Wind direction will change midweek when a cold front stalls northwest of Hawaii. Starting Wednesday, this will create lighter southeast winds, allowing land and sea breezes to develop. Light winds this weekend could bring either reduced daily rain patterns or concentrated showers on western slopes.
Boaters should note that a Small Craft Advisory remains active until early Tuesday. A northwest swell today will raise surf heights on north and west shores before calming midweek. Another swell arrives Thursday, with possibly high surf through Friday. East shore conditions remain rough today but will improve as winds decrease.
