The Lowdown

Alright, let me tell you how it’s looking for Off The Wall (Big Island). Water temp is sitting at 56°F, which is about 5°F colder than normal for this time of year – that’s properly unusual, so you’ll want a thick suit. The coming days are a mixed bag, but there’s a couple of windows worth paddling out for.

Right off the bat, Monday the 14th and Tuesday the 15th are pretty much a write-off. We’ve got a fresh cross-onshore wind at 19 to 22 mph and lumpy, poor surf. Combined wave energy is only moderate, around 621 to 626. Not worth your time.

Things start to turn around on Wednesday morning the 16th. Swell swings to the SW at 8 ft, period 13 seconds, and we get a clean offshore wind from the SSE at 22 mph. The energy jumps way up to 3721 – that’s strong stuff. But the wind is strong too, and at 8 ft it’s only for experienced surfers. The afternoon holds smaller at 6 ft with a strong offshore but still hard to paddle into.

Thursday the 17th and Friday the 18th stay similar: clean offshore winds, SW swell around 6 to 6 ft, but those winds are fresh to strong at 22 to 28 mph. The energy stays strong, between 1011 and 1795, but it’s marginal due to the wind strength making it tough to get into the waves.

Now, the standout window arrives on Monday the 21st. Monday morning gives us a light breeze from the SE at only 6 mph, offshore, with a 4 ft WSW swell at 12 seconds. The energy drops to 551, but the conditions are clean and the wind is light – that’s the kind of session where you can relax and enjoy. It’s not huge, but it’s good.

Tuesday the 22nd morning could be the pick of the whole period. Glassy conditions with a slight air from the SE at 3 mph, offshore, and a 4 ft SW groundswell at 13 seconds. Energy is strong at 1073, and the comment says excellent for experienced surfers. That’s the one to circle.

Wednesday the 23rd sees the wind pick up again, fresh offshore, but the swell drops to 4 ft – marginal.

Thursday the 24th offers another nice window. Both morning and afternoon have light breezes, offshore or cross-offshore, with a 4 ft SW swell at 12 to 13 seconds. Energy around 1057 and 558. Expect very good conditions – a solid option for a relaxed session.

The rest of the run into the end of September looks smaller, with some strong offshore winds and occasional clean conditions. The 26th and 27th have stronger winds, but the 28th Monday morning brings a light offshore breeze and a 4 ft SW groundswell at 15 seconds – very long period. That will peel nicely down the reef, but the sets will be few and far between. Clean though.

Overall, the best bets are Tuesday the 22nd morning and Monday the 21st morning for the cleanest, most user-friendly conditions. Thursday the 24th is also worth a look. The bigger days mid-week are for experts only, and the wind will keep things challenging.

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.
