The Lowdown
Alright, listen up. First decent surf isn’t until a couple days out, and then we’re gonna have to sit through a flat, choppy middle before something shows in the back half.
Starting with Trapdoors. It’s a point/river set-up, exposed, and tricky. Monday the 17th is not good – 5ft from the ESE, but the wind is cross-on and messy, period is short, only 7 seconds. The combined energy is moderate (337). Water temp is 19°, close to average.
Tuesday morning cleans up – 5ft ESE swell, light cross-off, 8-second period. It’s surfable. The energy is moderate (350). Wednesday morning is the true standout early on: glassy wind, 4ft ESE swell at 8 seconds. Clean, fun, but expect the crowd.
Thursday through Saturday is mostly tiny and weak. Swell drops to 2-3ft, combined energy dips under 100. A few glassy mornings but nothing worth paddling out for unless you’re bored.
Now for the good stuff. Monday the 29th – 4ft SSE swell, period up to 10 seconds, clean offshore wind from the SW. Energy hits 296. Then Sunday the 30th morning: 4ft SSE swell, 11-second period, offshore, and the energy climbs to 387. That’s a proper groundswell. On a point break, that period can make it run a bit straight but the shape and power will be there. Only for advanced guys.
September 1st Tuesday: 5ft SSE swell, 9-second period, clean cross-off wind, energy at 773. That’s solid. The afternoon goes to 3ft but a 15-second period – stupid long. Could be a dream if the tide lines up.
Best of the whole run? Sunday the 30th morning, that 4ft SSE swell with clean offshore wind. Next best is the glassy Wednesday 19th morning for a smaller, tidy session.
Lots of quiet in between, but the end of August and start of September has some real teeth.
Rusty.

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