The National Weather Service has issued a High Surf Advisory for Maui’s south facing shores effective through 6am Monday morning due to a pair of large south swells arriving over the weekend. The first of these swells will continue to build through Saturday, peaking sometime overnight into Sunday. We should see surf near head-high levels this morning with a rise to several feet overhead at the better exposed breaks. The best breaks may pull in larger sets from time to time if you know where to look. The second swell is expected to arrive Monday, reinforcing the then fading first swell around similar heights. Wave heights should remain elevated along south facing shores through early next week. A tiny to small east-northeast swell may offer weak short-period surf along the windward shores, but don’t expect anything good. This series of south swells was generated by a strong storm near New Zealand last weekend that aimed a significant long fetch in our direction over several days. Another low developed southeast of New Zealand last Sunday, tracking toward the northeast and eventually merging with the first storm. We should continue to see surf through Wednesday. There isn’t much action after this event, so get it while it’s here.

Today’s Surf Summary

South facing shores will rise into the 4-8+ foot range with the potential for some breaks to reach near double-overhead levels while other less exposed breaks stay small. East and northeast facing shores will remain tiny to small at 1-3 foot. North and northwest facing shoreswill also come in near flat at 1-3 foot. Select Upper West breaks may pull in wrapping south swell but will most likely stay near flat at 0-2 foot.

Weather Outlook for Saturday

The trades will decrease today and through Sunday as the remnants of former tropical cyclone Enrique move to the north of the islands. This will result in generally warm and humid conditions, with sea breezes bringing some afternoon showers over interior and leeward areas. During the nights, trades should remain strong enough to keep a few showers across windward areas, especially over the Big Island. A more typical trade wind weather pattern is expected to return by the middle of next week.

Water vapor satellite imagery shows an upper level ridge located across the E half of the island chain, and an upper level low centered far west-northwest of the aloha state. At the surface, a surface high remains centered far north of the islands. The trade wind pattern generated by this high will be interrupted through the rest of the weekend as a weak surface trough and an area of enhanced moisture, both associated with the remnants of former tropical cyclone Enrique, move to the north of the main Hawaiian islands.

Weakening tradewinds should allow for sea breezes to develop this afternoon and possibly again on Sunday. However, the trades should not drop completely, especially over windward areas. Thus, the afternoon/early evening pattern this weekend may become a hybrid with weak trades keeping clouds and showers over windward and mountain areas, while some leeward/interior areas of the smaller islands could experience cloud buildups and localized showers as sea breezes push inland.

Models show the upper level ridge over the islands weakening and migrating west during the next couple of days, while the low west-northwest of the islands gradually dissipates. The remnants of Enrique will bring deeper moisture just north of the state for the Sunday-Monday time frame, with model solutions suggesting potential for some localized heavy showers early next week, especially during the afternoon hours.

Tuesday should be a transition day as the remnants of Enrique migrate to the northwest of the main Hawaiian islands with sea breezes still possible in the afternoon. By Wednesday, the trough finally moves away from the area and allows for a more typical trade wind weather pattern to return.
