The Lowdown
Alright, this is Rusty coming to you live from the Off The Wall (Oahu) forecast. We’ve got a solid 16-day window ahead, but it starts off with a quiet little Friday and then builds into something truly special for the patient ones.
The water’s sitting at 56°, which is a bit colder than normal for this time of year, so don’t ditch the booties just yet.
The first few days are a gentle warm-up. Friday the 31st of July, we’ve got a clean 4ft SW swell pushing through with a nice 12-second period. The wind is light and offshore, so the wave faces will be tidy. It’s a good start, but nothing to scream about. Saturday the 1st of August, the morning glass-off is a treat with clear skies and a 4ft SW swell, period stretching to 14 seconds. That’s proper groundswell energy, and the combined energy is moderate (585). It’s a nice, cruisy weekend session.
Sunday the 2nd of August, the morning is a bit cross-on, but the afternoon turns glassy again with a 4ft WSW swell and solid energy (628). Monday the 3rd of August is where things pick up. The morning is glassy, with a 4ft SW swell and the combined energy jumps to 1005 – that’s moderate wave energy starting to thump. Conditions are excellent for experienced surfers, and the wave quality is spot on.
Tuesday the 4th of August gets a little messy, with cross-on wind and rising swell, but it’s the calm before the storm.
Now, Wednesday the 5th of August is a write-off. Big, junky, onshore wind at 16 mph pumping a 10ft swell into the reef. The combined energy hits 3599 – strong energy – but the conditions are poor. This is a day to stay on the sand.
Thursday the 6th of August is the first major standout. Morning brings a 15ft SW swell with a 13-second period, and the wind is offshore at 12 mph. The combined energy is a massive 6080 (very strong). This is exceptional surf, but it’s for experts only. That’s a big, heavy wall. The afternoon is even better, with the same size and clean offshore breeze. This is a day for the confident and the skilled.
Friday the 7th of August, the swell backs down to 10ft, but it’s still clean and powerful. The afternoon is excellent for experienced surfers. Saturday the 8th stays solid with 10ft WSW swell and clean conditions. Good, strong surf.
The swell drops a bit on Sunday the 9th and Monday the 10th, with poor wind and chop. That’s a lull, but it doesn’t last long.
Tuesday the 11th of August, things fire back up. The morning is clean with a 7ft WSW swell, 14-second period, and light offshore wind. The afternoon is the second major standout: 10ft WSW swell, 14-second period, and the combined energy spikes to 5159. It’s exceptional for experts. Clean, powerful, and the sets will be long and throaty.
Wednesday the 12th of August is a bit weird with cross-shore wind, but the swell is still solid at 12ft. Thursday the 13th is a write-off with rain and wind. Friday the 14th comes back clean with an 8ft WSW swell and offshore wind. Good, solid expert surf.
And then the final, absolute standout. Saturday the 15th of August. The morning delivers a 13ft WSW swell with a 15-second period, and the combined energy is 7463 (very strong). The wind is light and variable. The afternoon is even better – 15ft WSW swell, 15-second period, and the combined energy hits 9500. That is exceptional surf for expert surfers. This is the one you circle on the calendar. A true, world-class day at the Wall.
Remember, this is a reef break, and with these sizes, it’s strictly for the experienced crew. The crowds will be there, especially on the standout days, but the waves will be worth the lineup.
This is Rusty, signing off.

Information about the Off The Wall Surf forecast
The above surf forecast table for Off The Wall provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Off The Wall can be found by selecting the local surf guide option on the grey menu. Our Off The Wall 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 (Off The Wall) 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 Off The Wall 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.
