Looking Ahead

The next few days will see a veering of our winds. Our natural air conditioner will be turned off with light southeasterly winds in the forecast. Muggy conditions are expected. An old front that’s sagging south is expected to bring low clouds and rain as it reaches Hawai’i County sometime late Tuesday into Wednesday. Trade winds may make a return by the weekend, bringing trade wind weather along with them.

Surf & Seas

The above average north-northwest swell should be back down to average levels today, gradually fading through midweek. Today, heights are expected to be head high to overhead at spots best exposed to the swell. A moderate north-northwest swell (320 – 360°) is expected to start building Thursday afternoon. Some northwest swell action from Ana is also possible late in the week.

Swell generated by Ana continues to drop and a small south-southwest (200 – 190°) is expected to build in today, offering heights in the knee to waist high range. Gales well southeast of New Zealand could bring surf by the middle of next week.

Keep in mind, surf heights are measured on the face of the wave from trough to crest. Heights vary from beach to beach, and at the same beach, from break to break.
