The Lowdown
Alright, my friends, Rusty here again, this time in feet and Fahrenheit for you. Let’s talk Big Beach.
First up, I’ll keep it real: the next 16 days from Monday, August 24th through Tuesday, September 8th are a mixed bag, but leanin’ small. Monday and Tuesday are totally flat, weak, and the wind's all wrong – cross-off, nothing happening. Don’t bother.
Wednesday morning the 26th of August, finally we get a NE offshore breeze at about 9 mph. The swell’s still tiny, about 2ft from the SSW, but the combined energy is 454 (moderate), and it’s clean. Water temp is about 81°, right around normal for the season. If you’re a beginner or just want a mellow, glassy session, this works.
But the real standout of week one is Thursday morning, August 27th. Clean, gentle cross-off from the ENE, swell bumps to 3ft from the SSW with a 16-second period – that’s groundswell lad. The combined energy jumps up to 959 (strong wave energy) and the description says “very good” surf. That’s your best looking session for the first week. Not big, but clean and with some shape.
Friday through Tuesday, 28th to 1st, it’s all 2ft to 2ft, mostly clean but ordinary. Energy drops way down, like 170 on Saturday morning. Surfable but not memorable.
Now go to week two. Saturday the 5th of September, swell goes long – 2ft from SSW with a 20-second period, energy of 522 (moderate-to-strong), but wind is cross-off so it’s not perfect. Sunday the 6th of September though, that’s the one. Morning has a 3ft SSW swell with an 18-second period, combined energy at 902 (strong), and only a light breeze at 6 mph from the E. That’ll be glassy, clean, and the long period will give you nice spaced-out sets. Best day of the whole forecast. After that it fades again into Monday and Tuesday.
No big swell the whole time – nothing above 3ft – so the crowd factor at Big Beach will be moderate, especially on the clean mornings. Experts will be a bit bored, but if you want a clean, longboard-friendly wave, Sunday September 6th is the pick. No question.
Rusty.

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