The Lowdown
Alright, grab a coffee and listen up. It’s gonna be a frustrating one.
Right now, the surf is flat. I’m talking flatter than a pancake. We’re looking at a long stretch of nothing until we get a few days of very small, very poor waves that just aren't worth paddling for. The water temp at Halawa is sitting right on 80°, which is pretty average for this time of year, so no surprises there.
The first real pulse of energy we see is on Sunday, the 23rd of August. Halawa (Big Island) sees a chunky 7 ft swell from the ENE, but the wind is howling from the ENE at 22 mph, making it a lumpy, cross-shore mess. The wave energy is moderate (554), but honestly, it's blown out. That’s a no-go for paddle surfing, that setup is more interesting for kite surfing.
After that, the cross-shore winds just don’t let up. We’ve got a serious gap with no good surf. The next flash of something is on Wednesday, the 26th of August, with another 7 ft pulse from the ENE and moderate energy (369), but again, the wind is a fresh 19 mph cross-shore. It’s just choppy, lumpy, and messy.
The standout here, if you can call it that, is the morning of Wednesday, the 2nd of September. The swell is tiny, just 0.3 ft from the NW, but the wind is light and cross-offshore, giving us a clean surface. The period is a long 13 seconds, which is a groundswell, but there’s next to no energy (6). It’s a clean, flat, and glassy morning. That’s the best we get, but it’s a session for the longboard, not for power.

Information about the Halawa Surf forecast
The above surf forecast table for Halawa provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Halawa can be found by selecting the local surf guide option on the grey menu. Our Halawa surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Halawa) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Halawa may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
