Surf along south facing shores will remain small through early next week, with mainly background southeast and southwest swell energy expected. The next potential long-period pulse out of the southwest from the Tasman Sea is expected by Sunday and could lead to a slight increase in surf. For the extended forecast, strong to gale-force southwest winds associated with a low in the Tasman Sea may lead to another small southwest swell Tuesday through midweek.

A small northwest swell will continue into the weekend before easing. Another small reinforcement from that direction is expected to fill in around Sunday night through the middle of next week.

Weather Outlook for Saturday

Trade winds will gradually trend down this weekend as a ridge of high pressure to the north weakens and a weak surface trough slowly approaches from the east. Mainly windward clouds with light passing showers will prevail into early next week, with a possible boost in shower activity around the middle of next week as the surface trough moves through the islands.

Currently at the surface, a 1026 mb high is centered around 1750 miles north-northeast of Honolulu, and is driving light to moderate trade winds across the island chain early this morning. Meanwhile, a weak surface trough is located around 550 miles northeast of Hilo. Infrared satellite imagery shows clear to partly cloudy skies in place across the State, with some thin cirrus streaming northeastward over the Big Island. Radar imagery shows scattered light showers moving into windward areas, with predominantly rain free conditions elsewhere. Main short term concerns revolve around the diminishing trades and rain chances over the next couple of days.

Today through Tuesday, High pressure will weaken and shift eastward as the weak surface trough northeast of the state shifts slowly westward toward the island chain. This will result in a gradual easing of the trade winds this weekend, with mainly light trades expected for the first half of next week. Showers will continue to favor windward and mauka areas through the period, although some leeward shower development will be possible each day due to the weakened trades. Overall, fairly dry conditions are expected through the period given precipitable waters values in the 1.0 to 1.3 inch range, well below climatological norms for this time of year.

Tuesday night through Friday, The surface trough will shift westward across the island chain during the middle of next week. This should bring an increase in shower activity, as well as strengthening the trade wind flow back to moderate levels. Showers will continue to favor windward and mauka areas through the period.
