The Lowdown
Alright, Rusty here again, same story, different numbers.
The only break in the lineup is Haubush. Reef break, intermediate level, no place for beginners if it gets big. The whole 16-day window starts with nothing for days—don’t get your hopes up until the very end.
Tuesday morning, August 18th, we’ve got a small 3 ft S swell with a 13-second period—decent groundswell. Combined energy is moderate (579). But the wind is a cross-breeze at 16 mph, making a cross-chop. Water temp is 80°, right where it should be for this time of year. Not a session worth paddling for.
Wednesday and Thursday stay small and wind-affected, though Thursday afternoon gets glassy—wind drops to zero—with a 2 ft SW swell, 17-second period (very long groundswell). Clean, but the energy is moderate (399) and the surf is just “marginal.” A nice moment but no standout.
From Friday, August 21st, right through the next week, the wind cranks from the ENE, often 18 to 25 mph, cross, lumpy, messy. The swell jumps up a bit on the 23rd and 24th to around 6 ft, but it’s E windswell at only 7 seconds—short and weak. Energy hits 700+ but it’s poor. Not even kite surfing would be fun here with the wind direction—just blown-out reef crud.
The only real light comes on Tuesday, September 1st. That morning the wind turns cross-offshore from the NE at 16 mph, with a 4 ft SSW swell, 11-second period. Combined energy is strong (1026) and the waves are “clean.” By the afternoon it’s even better: NE at 9 mph cross-offshore, 5 ft SSW swell, 13-second period, energy at 1345. Still only “marginal” in the ratings, but it’s the best we get—clean lines, good groundswell, right direction.
Wednesday, September 2nd, carries that same clean cross-offshore wind from the NE, 16 mph, with a 5 ft SW swell, 12-second period, energy 1280. The afternoon mirrors it.
So the call is Tuesday, September 1st afternoon. That’s the true standout. It’s two weeks out so treat it as promising but not a lock. The rest of the 16 days is a long stretch of junk. Haubush (Hawaii) is usually fairly consistent, so this blank run is odd. It won’t stay crap forever.
Rusty.

Information about the Haubush Surf forecast
The above surf forecast table for Haubush provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Haubush can be found by selecting the local surf guide option on the grey menu. Our Haubush 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 (Haubush) 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 Haubush 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.
Haubush is 2 km (1 miles) from 'Ewa Beach. If you plan a vacation in Oahu, look for hotels and other accommodation in 'Ewa Beach. 'Ewa Beach has rooms for a wide range of budgets as well as car hire and transport links.
