The Lowdown
Alright, Rusty here. Let's talk about what's on the table for the next couple of weeks in this part of the world.
Look, I gotta be straight with you – it's a pretty bleak run ahead. The whole 16-day window is a struggle. There's nothing that I'd call a good, classic surf day. Most of the time the wind is howling out of the east, creating a messy cross-chop that just wrecks any chance of a clean face. You'll be paddling your guts out for lousy, bumpy lines. For a stretch there from the 17th through the 23rd, we see small, weak swells with very poor conditions, making it a proper write-off for anyone looking for a wave. Then, the last week of August and into September, the swell drops right off and the wind stays strong. It's just flat and blown out.
Now, if you're desperate, there are a couple of days where the raw power is there, but the quality is still a major issue. On Monday the 24th, the swell pushes up. We get a pulse of 8ft from the ENE with a period of short, dumpy 7 seconds. The energy reading is a chunky 595 (moderate wave energy), but it's arriving with a strong 22 mph cross-shore wind. That's a recipe for a messy, lumpy, and pretty unpleasant session unless you're a masochist. The only real stand-out in terms of size is Wednesday the 26th afternoon, where a 8ft ENE swell rolls in with a powerful 726 (strong wave energy), but again, the same problem – 19 mph cross-shore winds. At 8ft, that's expert territory, and with that chop, it's going to be a battle, not a pleasure.
At the beginning of the run, on Monday the 17th, the water temperature is 80°, which is bang on average for this time of year. That’s one small comfort, but it’s about the only one.
Honestly, for 99% of surfers, this is a two-week skip. With the persistent strong winds and small-to-overpowered lumpy surf, this setup looks more interesting for kite surfing than paddle surfing. So save your energy, take a break, and maybe the next forecast will have something better for us.
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.
