The Lowdown
G’day, I’m Rusty. Let’s get into it for Donkin Bay.
The outlook kicks off proper with a solid pulse arriving Tuesday morning, September 1. We’re looking at a 6 ft SW groundswell, period a nice 11 seconds, pushing through with a combined energy of 882 (moderate). The wind is a clean cross-off from the south at 9 mph, so the surface should be smooth. The water, though, is sitting at 54° – that’s a full 5° colder than normal for this time of year, so you’ll want a good thick steamer. This is the pick of the whole window. The morning is the standout session; the afternoon gets messy with a 19 mph cross-shore wind, lumpy, and the tide or something else just doesn’t line up.
Wednesday the 2nd holds a bigger 8 ft SW swell, very long 14-second period, and the energy jumps to 2161 (strong). But the wind is cross-shore, and the commentary says marginal conditions. It’s one for the experienced crew only – anything over 8 ft is expert territory, and this is close. The long period groundswell might make it wall up a bit straight at the beach, but it’s a reef and point set-up here, so that could actually work in its favour if the wind cleans up. Thursday the 3rd has a 10 ft SW swell (strong energy at 2555) but the wind is cross-shore and the report says it’s too big for this break. That’s a kite-surfing day if I’ve seen one.
After that, the swell drops hard. Friday the 4th offers a tiny 3 ft morning, but the afternoon has a 3 ft SSW swell with offshore ESE wind at 16 mph (clean, moderate energy 285). It’s a small window but the wind is good. The rest of the first week and into the second week is small and mostly poor. Saturday the 5th, Sunday the 6th, and Monday the 7th all have small swells under 4 ft with strong or gusty winds – not worth paddling out for.
There’s a gap of several days with no real recommendation. The only flicker comes Sunday the 6th afternoon with a 4 ft SW swell, 15-second period, and offshore SE wind at 16 mph (moderate energy 512). That’s clean but still small. Then Thursday the 10th afternoon shows a 6 ft WSW swell, 14-second period, and a gentle cross-shore wind (strong energy 1301). The comment says marginal, but it’s the only size in the second week. And Friday the 11th morning has a 6 ft WSW swell (moderate energy 1026) but cross-shore wind again.
The real standout is Tuesday morning, September 1. Good size, clean wind, solid energy. The water is unusually cold, but that’s just part of the package. After that, it’s a waiting game until the next pulse, but it’s not looking crisp.
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.
