The Lowdown
G’day, Rusty here, and we’ve got a solid 16-day window ahead for Donkin Bay (reef and point). The water temp is sitting about average for this time of year, so no surprises there. The pattern starts with small, clean, but not quite firing surf, then builds into a cracking run of solid, clean groundswell that’ll have the point reeling. There’s a big gap in the middle of the second week where it goes flat or messy, so don’t sleep on the good days.
The first real action kicks off Monday the 20th. Morning is clean with a light cross-offshore breeze, 5 ft SW swell at 10 seconds (moderate wave energy at 494). It’s a fun, manageable size – not too big, not too small. The afternoon gets a bit cross and drops off, so make the early call.
Tuesday the 21st morning is glassy – near zero wind, clean as a whistle, with a small 2 ft SW swell but a very long period of 15 seconds. That’s proper groundswell, and while it’s small, that long period will groom itself beautifully at Donkin Bay’s reef and point setup. Light energy (300), but it’ll be lined up and fun.
Thursday the 23rd morning is a standout. Clean again with a cross-offshore ENE breeze, 5 ft SW swell at 12 seconds (moderate energy at 568). The conditions are described as “very good” – this is a session you’ll be talking about.
Now, the real highlight is Friday the 24th. That morning is a beast for experienced surfers: 8 ft of SW groundswell with a 16-second period, generating very strong wave energy (2808). The wind is light and cross-offshore from the east, so it’ll be clean. This is big, powerful, and long-period – it’ll be working best on the reef and point, but it’s only for those with the skills. The afternoon stays clean with 7 ft, but the wind picks up a little.
Saturday the 25th is another cracker. Morning brings 6 ft SW swell at 13 seconds (strong energy at 1164), clean with a cross-offshore breeze. The afternoon turns offshore from the southeast at 12 mph, with 6 ft SW at 13 seconds (strong energy at 1034). That’s the kind of afternoon that gets you stoked – clean, offshore, proper waves.
Sunday the 26th morning is a write-off – 25 mph NE wind, just messy. The whole of the next week goes quiet, with poor surf or small, wind-affected dribble until Monday the 3rd of August when a 6 ft SW swell at 15 seconds rolls in, but with a heavy onshore wind, it’s not worth paddling out for.
The best of the window? Definitely Friday the 24th and Saturday the 25th. Big, clean, long-period SW groundswell with light offshore winds. Crowds are possible at Donkin Bay, but with waves this good, you’ll be smiling anyway.
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.
