The Lowdown

Alright, let’s break this down, Imperial style. Things are pretty quiet around Big Beach to start, but there’s some real potential coming in the second week if you’re patient.

Right now, we’re in a flat spell. On Wednesday morning July 29th, you’ve got glassy conditions with a 2ft swell from the SSW, period around 13 seconds. Water temp is 80°, which is about normal for this time of year. The combined energy is weak (212), so don’t expect much push. It’s small, clean, and mellow—fine for a log but not for any power moves.

Thursday the 30th sees a slight bump to 2ft from the south, with a little more energy (346). Cross-off winds keep it clean. Then Friday through the weekend, the swell drops back to around 2ft and then 1ft by Sunday. Winds build to a moderate breeze, but there’s a window of offshore on Saturday morning. Still, it’s tiny. This stretch from July 31st through August 5th is really slim pickings—small, weak, and not worth getting excited about.

Now, here’s the good part. Come Saturday August 8th, we see a jump in energy to 365 with a 2ft SSW swell and a period of 14 seconds. It’s not big in height, but the period is solid. Morning looks best with light cross-off winds. Then Sunday August 9th is a real standout: 2ft from the SSW with a very long period of 18 seconds. That’s proper groundswell energy at 562, meaning cleaner, more powerful waves with longer sets. Not big enough to close out, but it’ll be fun.

The crown jewel is Monday August 10th. Swell holds around 3ft to 4ft from the SSW, with periods of 15 to 16 seconds. Combined energy hits 681 to 740—that’s moderate to strong. Winds stay light cross-off, conditions clean. This is your best day. Big enough to have some punch but still under 5ft, so it’s fine for intermediate surfers. Just remember, with that long period (15-18 seconds), the waves might be a bit straight on a beach break, but there should be some juicy lines.

After Monday, Tuesday through Wednesday holds some 3ft to 3ft swell, but energy drops and winds pick up in the afternoons. By Thursday August 13th, it’s back to small and weak.

Crowds at Big Beach are “sometimes” crowded, so expect some company on the better days. This break is very consistent, so even the small days offer something to ride.

The takeaway: first week is a bust. The standout is Monday August 10th with that 3ft to 4ft groundswell and clean conditions. Sunday the 9th is also a great call. If you’ve got the patience, it’ll be worth the wait.

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.
