The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a bit of a slow start on the cards for Donkin Bay, a reef and point set-up that needs a solid south-west swell to really light up. The water is sitting at 53°, which is a whopping 6° colder than usual for this time of year – that’s seriously unusual, so you’ll want a thick hood and gloves if you’re heading out.
The first real chance of a wave comes Thursday morning, the 3rd of September, but it’s a write-off. We’ve got a 6ft WSW swell (13 second period) with a fresh 19 mph onshore wind, creating a messy 1170 combined energy (moderate). It’s poor, so don’t bother.
Friday the 4th is where things get a little more interesting. The morning is still a bit rough with a 3ft SSW swell, but by the afternoon, the wind swings SE at 16 mph and goes offshore. That cleans up the 4ft SSW swell (10 seconds) nicely. The combined energy is 369 (moderate). It’s not huge, but it’ll be clean and fun for an intermediate.
Saturday the 5th is small and ordinary. A 2ft SSW swell in the morning with offshore wind is surfable, but nothing to write home about. The afternoon drops to 1ft – forget it.
Sunday the 6th is a tease. The morning shows a 4ft WSW swell but with a massive 18-second period, giving it 1057 combined energy (moderate). The problem is the wind is cross-off at 19 mph, which messes with the shape. This long period groundswell is better suited for a point or reef, but the wind is the killer here.
The standout window starts to shape up on Tuesday the 8th of September. Morning glass-off, zero wind, with a 4ft WSW swell at 12 seconds (437 combined energy). That’s clean, smooth, and perfect for a reef. Conditions are good, and this is your best early bet.
Then we hit Wednesday the 16th of September. This is the one. The morning offers a 5ft SW swell, 14-second period, combined energy of 1133 (strong), with a slight SE breeze making it cross-off and clean. The report says it’s excellent for experienced surfers. This is a true standout. The swell direction matches the optimum SW, the wind is clean, and the energy is pumping. Get on it.
Later that same day, the wind shifts and the afternoon gets messy, but the morning session is the gold.
Further out, Thursday the 17th and Friday the 18th see a massive pulse of swell. Thursday morning brings a 8ft WSW swell with an 18-second period, but the cross-wind is a fresh 19 mph, making it lumpy. By Friday the 18th, the swell is 13ft (WSW) with a 15-second period, which is way too big for this break. The combined energy is 7941 (very strong), but it’s just too much. Kite surfers might have a field day, but for paddle surfing, it’s a pass.
So, to wrap it up: the best on offer is the morning of Tuesday the 8th for a clean, glassy session, and the absolute standout is the morning of Wednesday the 16th of September for a proper, powerful, clean swell.
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.
