The Lowdown
Alright folks, Rusty here with a look at the surf ahead. We’re focusing on one spot for this run, and it’s a bit of a mixed bag.
For most of this week and into the next, Donkin Bay is going to be tough to call. The water temp is sitting at a very unusual 55°, which is a full 4° colder than normal for this time of year – that’s a proper winter chill.
The start of the week is a write-off. Monday the 14th and Tuesday the 15th are a complete no-go with strong to fresh cross-onshore winds and poor, lumpy surf. The combined wave energy is moderate at best (272 to 530) but it’s just messy. We have a long gap of poor conditions before anything worthwhile shows up.
Now, the standout window is from Wednesday the 16th through to Saturday the 19th. Wednesday afternoon (16th) is your first real look. We’ll see chest-high swell at 5ft from the WSW, with a solid 13-second period (a good groundswell). The wind switches to a light offshore from the ESE, and the energy is strong (1539). The forecast says it’s excellent for experienced surfers – this is the pick of the bunch for a clean, punchy reef and point setup, but the size (over 5ft) means it’s not for beginners. Thursday the 17th keeps the momentum with clean, 6ft SW swell and gentle offshores in the morning; the energy is still strong (1140). Saturday the 19th morning also offers a good chance with moderate offshore wind and 5ft SW swell (energy of 778), but crowds are possible here, so get there early.
After that flurry, conditions drop off again. Late in the second week, we get a few interesting mornings. Monday the 22nd (Tuesday morning) is worth a mention – clean conditions with a light offshore, 4ft of SW groundswell ticking in at a very long 14-second period. The energy is moderate (796). That long period will make the waves at Donkin Bay feel punchy and powerful, but the long gaps between sets might make it feel a bit inconsistent. Wednesday the 23rd is similar, with cleaner but smaller surf.
By the final weekend (27th-29th September) the swell backs off to around 3-4ft, and the winds are mostly onshore or cross. It’s a poor end to the outlook. The energy drops right back to weak to moderate levels (around 272-538). Not worth getting excited about.
Best on offer: Wednesday the 16th afternoon (5ft WSW, offshore, strong energy) and Thursday the 17th morning (6ft SW, clean, strong energy). Those are your prime windows for some properly lined-up reef waves. Get on it.
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.
