The National Weather Service has issued a High Surf Advisory for Maui’s south facing shores effective through 6am Monday morning due to large long-period surf exceeding 8 foot faces. This energy will continue through Sunday and may still offer good sized surf Monday morning with a slow fade through the middle of the week. Additionally, a new west-northwest swell will fill in today, offering head-high+ surf along our north shores and select west exposed shores as well. This action will be followed by yet another round of northwest swell arriving Tuesday into Wednesday. Be aware that the more westerly swell direction will result in heavy island shadowing, so don’t be surprised if you have to hunt for decent surf along the north shores. This current south swell was generated last week when a powerful storm passed south and east of New Zealand, aiming a significant fetch aimed east of Hawai`i. The largest surf will pass us by to the east but we should still pull in plenty well overhead surf for several days. Select breaks may offer up double-overhead surf if you know where to look. Hopefully this swell will slowly fade through Wednesday before our summer shores return to flatness. The west-northwest swell was produced last week as a strong but compact storm near Japan aimed a fetch in our direction. This low continued to track into the northwest Pacific and developed an additional northwest swell over the past few days. It is slowly fading along the Aleutian Islands as it nears the Gulf of Alaska. Looking out into the long-range models isn’t very promising, but there is a slight chance for another northwest swell developing around the middle of the week. Not much more than background swell is likely to come out of the southern hemisphere through the forecast period. Get it while it’s here and have fun this week!

Today’s Surf Summary

South facing shores should offer surf in the 5-8+ foot range at the better exposed breaks, while many breaks stay on the smaller side. Double-overhead sets are possible at the best exposed locations, but you’ll have to know where to look. North and northwest facing shores should offer surf in the 4-6+ foot range at select exposed breaks, but don’t be surprised to find much smaller surf at many breaks due to the westerly component of this swell. Upper West shores will likely stay flat at 0-2 foot. Windswell along the east and northeast facing shores will stay tiny at 1-3 foot.

Weather Outlook for Sunday

Hot and humid conditions will continue into next week. Light winds will persist through Wednesday, allowing for afternoon sea breezes and muggy conditions. Clouds and spotty showers will form in the afternoons with overnight land breezes clearing skies. Light trade winds are expected for the second half of the week.

Low pressure northwest of the state has cut off trade winds, leaving the islands under a stable convective regime. Sea breezes and spotty afternoon showers will form in the afternoons, with gentle downslope flow and clearing skies at night. Light northerly flow near the surface is slowly pushing an old frontal boundary associated with the aforementioned low toward the state.

Moderate showers have popped up along a low level convergence band just north of Kauai. The band is currently located across the northern coastal waters of Kauai and moving slowly south. Skies will cloud up over the garden isle this morning with some showers expected over the mountains and the northern and eastern slopes. Oahu will see increasing cloudiness later this morning as the low clouds push in from the north. By the afternoon, most areas will have at least partly cloudy skies as sea breezes kick in and daytime heating is at its maximum. Spotty showers are expected with some brief downpours possible.

Current dew points around the state are hovering around 70 degrees, making weather conditions feel sticky and uncomfortable. Similar conditions are expected for Sunday. As the old frontal boundary reaches the islands Monday, dew points will increase into the low to mid 70’s. Combining these higher dew points with high temperatures near 90 degrees f, and afternoon conditions will go from sticky and uncomfortable into the oppressive range. Slightly lower dew points are expected Tuesday and Wednesday, but the hot and humid conditions will remain.

A weak high pressure to the northwest will bring light trade winds back to the islands Wednesday and for the second half of the week. However, muggy conditions will continue. The trades will focus showers over the windward slopes but afternoon leeward sea breezes will bring spotty clouds and limited showers to leeward and interior areas.
