The Lowdown
Rusty here. Let’s break down the 16 days at The Patch.
Water temp is 16°, which is a touch warmer than normal for this time of year – that’s a nice little bonus. The Patch is an exposed SW-facing spot that needs that southwest swell to work.
First off, the beginning is quiet. Thursday the 20th and Friday the 21st of August have tiny clean waves, around 0.6-0.8 ft, but cross-off breezes and weak energy (346-398). You could get a longboard out, but it’s not worth stressing about.
Saturday the 22nd is flat. Skip it.
Sunday the 23rd bumps up to 4 ft from the WNW, but period is only 8s and wind is cross-onshore. Messy. Monday the 24th through Wednesday the 26th stay small and marginal.
Now, Thursday the 27th of August morning is the first proper standout. We’ve got 6 ft of NW swell, short period (7s), but combined energy reaches 888 (moderate to strong), and the wind is light cross-off from the WNW. That’s clean and punchy. Crowds are “sometimes” here, so you’ll have company but not a circus. Best for the shortboard crew.
Friday the 28th drops to 5 ft with cross-shore wind—not as good. Saturday the 29th stays smaller.
Sunday the 30th of August morning: big one. 7 ft from the NW, short period, energy at 1268 (strong). This is expert-level. Messy cross-shore wind. Leave it for the hardcore crew.
Monday the 31st of August morning is another highlight: 6 ft from the NW, 8s, light cross-off, 854 energy, very clean. That’s a fun morning.
Tuesday the 1st of September morning holds 5 ft from WNW, clean again.
The first week of September keeps solid WNW swell in the 5-7 ft range, most mornings clean and cross-off. Wednesday the 2nd is smaller with cross-shore wind, but afternoons pick up with clean 7 ft sets.
Friday the 4th of September morning is a monster: 8 ft from the NW with onshore wind and energy of 1456. If the wind shifts, it could be a beast, but right now it’s messy.
Best bets: Thursday 27th August morning for that first clean, punchy 6 ft, and Monday 31st August morning for 6 ft clean, light wind, and solid energy. Both are worth the drive.
There’s a dry stretch from Saturday 22nd through Wednesday 26th—roughly four days of barely any surf.
The Patch is fairly consistent overall, so this quiet spell is normal for the area. Stay optimistic—the back half of the window delivers.
Rusty, out.

Information about the The Patch Surf forecast
The above surf forecast table for The Patch provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The Patch can be found by selecting the local surf guide option on the grey menu. Our The Patch 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 (The Patch) 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 The Patch 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.
