The Lowdown
Righto, let’s have a look at what’s on the cards for the next couple of weeks. To be honest, it’s a pretty grim stretch at Halawa for a while. There’s no real surf worth paddling out for until the very end of the period, and even then it’s not looking great.
The water at Halawa is sitting at 80°, which is pretty much bang on average for this time of year – nothing wild there.
For the first week and a half, from Thursday 20th August right through to Tuesday 1st September, it’s a real write-off. The wind is mostly cross or cross-onshore, often fresh and lumpy, and the swell is tiny – mostly under 3 ft, with periods all over the place but mostly short. The energy is weak, often well under 100 (36, 62, 27, 40 etc). The wave comment is “poor surf conditions” across the board, so there’s just nothing to get excited about. There’s a brief blip on Sunday 30th August where the swell picks up to 7-7 ft from ENE with a 13-second period, and the energy jumps to 1393-1528 (moderate-strong), but the wind is still fresh cross-onshore and lumpy. It’s too messy.
The only window that might be worth a look is around Tuesday 1st September. The swell builds to 12 ft from ENE, with a 10-second period, and the energy is a massive 2270 (strong-very strong). The wind is light cross-onshore (6 mph), so it’s not completely blown out. But with that size and a short period, it’s going to be wild and only for experienced surfers who know what they’re doing. The wave comment is “marginal” at best, so keep expectations low.
Bottom line: the first 11 days are a total bust. Then around Tuesday 1st September there’s a chance of some big, messy, and tricky conditions. If you’re an expert and don’t mind a bit of cross-onshore chop, that’s your best bet. Otherwise, I’d sit this one out.

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.
