The Lowdown
Alright, Rusty here again. We're looking at a couple of weeks of solid SW groundswell for Donkin Bay, a reef and point that loves a good west-southwest pulse. There's some serious potential in this window, but the wind is going to be the deciding factor.
We kick off Tuesday the 18th with a clean morning. Swell is around 6.5ft from the WSW with a 13-second period, and that light cross-offshore breeze is going to make it glassy. The energy is strong, around 1246, so there's plenty of grunt. But the afternoon wind shifts and chops it up, so get on it early.
Wednesday the 19th is a bit of a washout with stronger cross-shore winds. Not your day. Wait for Thursday the 20th. The morning session is the pick again, a clean 6.5ft of SW swell with a light cross-offshore breeze. It'll be good, but the wind is mean to the afternoon. Friday the 21st has a little less size, around 5.5ft, but the winds stay light. It's ridable, but nothing special. Saturday the 22nd is small and poor.
Now, Sunday the 23rd is a proper standout. The morning brings a new 6.8ft WSW swell at 13 seconds, combined with that light cross-offshore wind. It's going to be clean, powerful, and well-shaped. That’s a top-tier morning. Monday the 24th is still fun first thing with 4.9ft, but the afternoon is no good.
Looking into the second week, Tuesday the 25th is a special one for the crew who like a longer paddle. A 15-second groundswell from the SW rolls in, with 4.9ft to 5.5ft of swell. The morning is glassy with offshore winds. It’ll have that push and shape, but expect longer waits between sets. That’s a classic point break day.
Now, hold onto your boards for Friday the 28th. The afternoon is looking huge. The energy readings go through the roof, up to 11629, with a massive 11.4ft SW swell. That's a serious day. Only the experts will be out, and even then, it could be too much for this spot.
The following weekend, Saturday the 30th, has clean surf in the morning, and Sunday afternoon looks like a beauty with a light offshore breeze and 6.8ft of SW swell. That’s a good call. But by Monday the 31st, the onshores return and it gets messy.
For the start of September, the 2nd looks fun with a glassy morning and 4.5ft of WSW swell. That’s a good one for a wider range of surfers. Water temp is about normal for the season, so a full suit is still the go. Donkin Bay can get busy on the good days, so be prepared for a few others out there. The main events are the mornings of the 18th, 20th, and the 25th, and the big one to watch is the 28th. That's for the brave. Keep it salty.

Information about the Donkin Bay Surf forecast
The above surf forecast table for Donkin Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Donkin Bay can be found by selecting the local surf guide option on the grey menu. Our Donkin 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 (Donkin 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 Donkin 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.
Donkin Bay is 136 km (84 miles) from Saldanha. If you plan a holiday in West Coast, look for hotels and other accommodation in Saldanha. Saldanha has rooms for a wide range of budgets as well as car hire and transport links.
