The Lowdown
Alright, crew, Rusty here with the lowdown on Donkin Bay. It's a 16-day forecast, and it's a real mixed bag, so let's break it down.
The water's at 55°, which is a solid 4° colder than normal for this time of year. That's a big chill, so don't be a hero, suit up properly.
The first real event is on Sunday, the 9th of August. There's a hefty 10ft SW swell rolling in, but it's too much for this spot. The wind is a strong 25 mph from the S, keeping it cross-off, but the wave energy is massive (2375). This is for the brave or the foolish.
Now, for the real highlight: Monday morning the 10th. The swell drops to a much more manageable 6ft from the SW, with a clean 11-second period. The wind is a light 9 mph from the SE, keeping it clean. The energy is solid (743). This is your window for clean, fun waves. The break is fairly consistent, so you'll get plenty.
The rest of that first week is a write-off. From Tuesday the 11th through Friday the 14th, it's all strong winds and lumpy, choppy conditions. The swell is around, but the wind just wrecks it.
The next decent chance is Saturday morning the 15th. The swell is a solid 6ft from the WSW, but the wind is a light 3 mph from the WSW, which is cross-on. Not ideal, but rideable. The energy is moderate (1139). Sunday morning the 16th looks better, with a 5ft WSW swell and a light 6 mph S wind being cross-off (828). That's a clean session.
Then we get the big one. Monday the 17th has a huge 8ft WSW swell with a long 16-second period. The energy is through the roof (3549), but the wind is light and cross-on. This is a long-period groundswell, and at a reef and point, it could be an epic session for the experts. The long period means long, powerful waves, but you'll have to be patient for the sets. Crowds are possible, so get there early.
The second week is a bit of a blur. There are some small, clean windows, but nothing jumps out. The best of the rest is probably Thursday morning the 20th, with a 6ft SW swell and a light 6 mph E wind blowing offshore (984). That's clean.
The real sleeper is Saturday morning the 22nd of August. The swell is a tiny 4ft from the SW, but the wind is from the NW at 3 mph, which is glass. Absolutely flat. The energy is low (347), but for a clean, small wave session on a point, that's a rare gift.
So, the plan is: hit Monday the 10th for the cleanest all-round surf, and keep an eye on Monday the 17th for the big, powerful groundswell if you're up for it. That glassy morning on the 22nd is a special one for the loggers.
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.
