The Lowdown
Alright folks, Rusty here with a look at what’s on the cards for Donkin Bay over the next couple of weeks.
Right off the bat, the next week and a half is looking pretty grim. We’ve got a bit of swell, but the wind and conditions are just stuffing it up for the most part. It’s a real shame because there’s some strong energy in the water at times, but it’s not coming together for a decent paddle. The water at Donkin Bay is sitting at 54°F – that’s a whopping 6°F colder than usual for this time of year, which is very unusual. You’ll want a good, thick wetsuit.
Let’s start with this Wednesday morning (2nd September). There’s a solid 8ft SW groundswell (period 14 seconds) moving in, with the combined energy hitting a beefy 2161 (moderate to strong wave energy). But the wind is crossing from the SSW at 9 mph, putting a slight chop on it, and the tide or conditions are just marginal. It’s a bit of a tease. By Wednesday afternoon, the wind is up to 16 mph and the swell drops a touch. Not the one.
Thursday (3rd September) is a write-off with onshore winds and rain showers messing up a 6ft WSW swell. Friday (4th) goes clean, but we’re dropping down to a small 3ft swell with a short 10-second period and a 22 mph SSE wind – it’s a cross-offshore but it’s too breezy for good shape.
We limp through the weekend (5th-6th) with tiny waves and onshore winds. Saturday morning sees a clean 3ft SSW swell, but it’s short period and hard to paddle into with a 19 mph offshore. Sunday (6th) we see a very long period 18-second groundswell, but it’s 4ft and the wind is onshore from the NW. That long period will make it break too straight at a beach break anyway, so no dice.
Monday (7th) and Tuesday (8th) are still poor, but Tuesday morning is a tiny bright spot. The wind goes glassy at 3 mph from the WSW, and there’s a 4ft SW groundswell. The combined energy is only 358 (weak to moderate), so it’s small, but glassy conditions at a reef and point setup might give you a few clean little runners. It’s a “surfable but ordinary” kind of deal.
Honestly, from now until the middle of next week, it’s a 10-day gap with nothing worth the effort.
Now, if you’ve got patience, we’re looking at some real promise for the 17th of September (Thursday). We’ve got a big 10ft SW swell rolling in with a 14-second period. The combined energy is massive: 3550 on the Thursday morning (strong wave energy). The wind is cross-shore from the SSW at 12 mph, which is okay, but this is a lot of water. At 10ft, this is only for the experts. It’s predicted to be too big for Donkin Bay itself, so I’d be looking for a more protected corner if you’re not a charger. For those who are, that’s the best energy on the whole forecast.
If that’s too big, the 16th of September (Wednesday) afternoon has a pulse of 5ft WSW swell with a very long 19-second period. The energy is 2369 (moderate to strong). It’s small enough for intermediates, but that 19-second period means it needs a good point or reef to line up. Donkin Bay is a reef and point, so it could work, but the wind is crossing, so it won’t be perfect.
So, the standout is the 17th of September for the big swell energy, but only for the brave. The Tuesday morning (8th) glassy session is your only real chance for a clean, small wave paddle in the near-term. Everything else is a skunk.
Rusty.

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.
