The Lowdown
Alright, folks, Rusty here. Let’s get into it.
Right off the bat, I gotta be straight with you. The next 16 days look bleak for Halawa. This is a reef and river setup that’s exposed to the swell, but we’re just not getting the goods. The whole outlook is a long stretch of poor surf conditions, with a real gap of nothing worth paddling out for running from now all the way through the end of the month. It’s a tough run.
The only hint of something happening is way out in the distance. On Monday the 31st of August, we start to see some size, with the swell climbing to 8 ft from the ENE. That’s solid, but it’s pushing into expert-only territory. The period is a short 8 seconds, so it’s windswell, not groundswell, meaning it’ll be a bit lumpy. The combined wave energy is strong at 714 (strong), but the wind is a cross-shore breeze at 12 mph, so it’s not going to be clean. It’s a marginal call, and honestly, for a setup like this, that much size with cross-shore wind is going to be a messy, challenging session. The water temperature is 80°F, which is bang on average for this time of year, so at least you won’t be cold while you’re getting worked.
The rest of the period is a write-off. We’ve got tiny swells, cross-shore winds, and a lot of chop. On the 2nd of September, we get a glassy morning with a tiny 0.3 ft swell from the NW, but that’s a lake, not surf. There’s nothing here to get excited about.
So, if you’re desperate, keep an eye on that Monday the 31st of August, but don’t hold your breath. It’s a long, dry spell ahead.
Rusty.

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.
