Honolulu residents and visitors can expect a brief respite from the recent showers as more stable air begins to make its way across the island chain. The National Weather Service in Honolulu reports that a weak low-level trough that was near Kauai has moved west, which will decrease shower activity while strengthening trade winds through Wednesday. However, prepare for an increase in showers starting Thursday through the weekend, as another disturbance is forecasted to move through the islands.
According to the NWS Honolulu forecast, the trade winds will remain moderate to breezy through Thursday. A gradual slowdown is expected starting Friday, which may bring smoother sea breezes to sheltered western slopes. These changing weather patterns will impact both land and marine conditions. A Small Craft Advisory (SCA) is in effect for all Hawaiian coastal waters until Wednesday evening due to the ongoing winds.
For those flying, the aviation outlook looks clear, with VFR conditions expected in most areas over the next 24 hours, according to the NWS. However, pilots should be cautious of possible moderate low-level turbulence downwind from the islands due to stronger easterly trade winds. Additionally, a High Surf Advisory is in effect for north-facing shores through the evening, where higher-than-usual surf is expected.
Mariners should pay attention to the Small Craft Advisory in effect due to strong trade winds, which will continue through Wednesday and ease slightly afterward. North-facing shores are expected to experience moderate to large north swells that will start to decrease later in the week. East shore surf will also rise a bit because of the stronger trades but is expected to diminish into the weekend as the winds ease.
