The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks.
Honestly, the outlook is a tough one for a while. We’ve got a long stretch of messy, lumpy conditions with onshore winds and cross-chop that will make you work for nothing. The swell is there, but it’s short-period, wind-affected junk. From Saturday, August 29th right through to early September, it’s pretty much a write-off. The wind is a fresh breeze from the east or east-northeast, blowing 18 to 19 mph, creating lumpy, cross-shore or cross-onshore conditions. The water temperature is sitting right around 80°, which is normal for this time of year, so no worries there.
The first real spark of hope shows up on the 8th of September. Tuesday afternoon sees a big jump in energy, with the combined energy of all swells hitting 1612 (strong to very strong wave energy). The swell is 10 ft from the east-northeast with a 10-second period. That’s a solid, powerful swell, but it’s borderline expert territory at that size, especially with the wind still fresh and cross-shore. It’s marginal, but there’s potential if you’re a strong paddler. The 9th of September (Wednesday) holds similar energy, around 1340, with a 9-second period and moderate cross-shore breeze, which might be a touch cleaner. Still, lumpy cross-chop will be a factor.
Then we get a real oddball. On the 11th of September (Friday morning), the swell drops to just 0.7 ft from the west, with a long 12-second period. The wind goes light and cross-offshore from the southeast. That’s a clean, glassy window, but there’s almost no wave energy—combined energy is only 10. It’s a tease. The 12th of September (Saturday morning) brings a little more: 3 ft from the north-northeast, 8-second period, and a fresh offshore wind from the south. That’s clean, with 88 combined energy. Saturday afternoon builds slightly to 101, still moderate offshore breeze. That’s your best small-wave window, but it’s tiny.
If I have to pick one standout, it’s really the 8th and 9th of September for the bigger, more powerful swell, but it’s only for the experienced crew. The 12th of September (Saturday) mornings offer the cleanest conditions, but with ankle-to-knee-high waves. Halawa is a reef/river setup, so it’s a spot that can handle a long-period groundswell, but it’s fairly consistent and exposed to the east-northeast, which is where all the messy swell is coming from. Crowds are possible there sometimes, so keep an eye out.
Overall, it’s a long blank run with a few small windows. Hang in there, the forecasts can change.

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.
