The Lowdown
G’day, Rusty here. Look, I’ll level with you—this stretch is a tough one. Halawa (Molokai) is a reef and river setup that’s fairly consistent, but over the next 16 days, the surf just isn’t cooperating. The water temp is sitting at 80°, which is about average for this time of year, so no surprises there. But the wave energy is weak to moderate at best, with most days showing combined energy under 100 (42) to a bit over 200 (222) on the better afternoons, and the wind is almost always cross or cross-onshore, keeping things choppy and messy.
From Wednesday the 19th through to Tuesday the 1st of September, it’s a long blank run. Every session is flagged as “poor surf conditions,” with heights mostly under 5 ft, short periods around 6–8 seconds, and onshore breezes freshening up to 18–25 mph. The swell direction is all over the place—NE, ENE, NW—but nothing lines up with the optimum NNW direction for this spot. The only real standout might be on Wednesday September 2nd and Thursday September 3rd, when the swell picks up to 6 ft to 7 ft from the ENE, with periods around 10–11 seconds and combined energy jumping into the strong range (756 to 1337). But even then, the wind is still cross-shore, and the forecast is marginal—these are more for experienced surfers keeping an eye on things, not a solid bet. That’s about as close to a highlight as we get, and it’s still a week and a half away, so don’t hold your breath. For now, the setup looks more interesting for kite surfing than paddle surfing, with that strong wind and lumpy cross-chop. Rusty out.
Short Range ForecastMostly dry. Warm (max 26°C on Thu afternoon, min 25°C on Wed morning). Winds increasing (light winds from the E on Thu afternoon, fresh winds from the E by Fri night). | Days 4-6 Weather SummaryMostly dry. Warm (max 26°C on Sat morning, min 25°C on Sat night).

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.
