The Lowdown
Alright, Rusty here again, with the imperial version for those who think in feet.
The outlook for the next couple of weeks is a bit of a slow burn. We’ve got a real flat patch starting now, with nothing worth paddling out for until late on Friday, the 21st. After that, it’s mostly small and messy, so patience is a virtue.
Widemouth Bay – The first glimpse of hope is on Friday morning, the 21st of August. The swell is tiny, just 2ft from the west with an 8-second period, and the combined swell energy is weak (75). But the wind is glassy out of the ENE at 3 mph, so it’ll be smooth as butter. For beginners or anyone on a longboard with a bit of foam, it’s a fun little session. The water temp is about normal for the time of year.
After that, the weekend (22nd and 23rd) is a bust – waves barely a foot, with the wind offshore or cross-offshore, but there’s no power. You’d be better off having a surf check and staying on the beach.
We get a slight nudge on Tuesday morning, the 25th of August, with 2ft of west swell at 10 seconds. The wind is cross-offshore from the SSE at 16 mph, keeping it tidy, but the energy is still weak (78). It’s a “if you’re desperate” kind of session.
Now, the one to get excited about: Tuesday, 1st of September. A solid 8ft west swell with an 11-second period, and the combined swell energy is strong (1230). The wind is cross-shore from the SSW at 16 mph, so it’ll be a bit lumpy, but for the crew who know what they’re doing, this is the day. The size is pushing 8ft, so it’s experts only – leave the soft-tops at home. Crowds will be a thing at Widemouth Bay when the swell pumps like that.
Before that, the 28th and 29th of August bring some size – 6ft and 7ft – but the wind is cross-onshore or onshore, and the quality is poor. Honestly, that’s more of a kite surfing show than a surf session.
So, in short: get out for that glassy, tiny session on Friday morning (21st) for a clean paddle, or mark your calendar for Tuesday, 1st of September for the big stuff. It’s a long way out, so don’t book the day off just yet, but keep it on your radar.
Rusty.

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