The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
Right off the bat, we’re looking at a pretty mellow stretch. The swell is hanging around the 2 to 3 feet mark for most of the run, so nothing huge. The standout is going to be Big Beach, a very consistent spot that’s fairly exposed to the swell. The water temp is sitting at 80°, which is about normal for this time of year.
We kick off Friday, July 24th with a bit of a whimper. The swell is 3 feet from the SSW with a very long period of 17 seconds, and the combined energy is moderate at 864. The wind is a cross-off, so the surf is clean, but the report says it’s marginal. Not our best day.
Saturday, July 25th is where it gets interesting. We’ve got a morning session with 3 feet SSW swell, a long 19-second period, and a gentle offshore wind. The wave energy is still moderate at 786, but the conditions are pegged as very good. The afternoon holds the same promise with a fraction more size at 3 feet and 18 seconds. The combined energy is 708. This is the best we’re going to see in the first week. The offshore wind means it’ll be clean, and with the long period, the sets will have some punch but won’t be too frequent, making it a good session.
Sunday the 26th through Tuesday the 29th, the swell drops a bit and the wind shifts around, but it stays mostly clean with offshore or cross-off breezes. The energy drops down to the 200-500 range, and the heights hover around 2 to 3 feet. It’s surfable, but nothing to get too excited about. Things get a bit messy on Wednesday the 29th with a cross-on wind, so that’s one to skip.
From Thursday the 30th through the end of the first week into August, the swell fades further. Heights drop to 2 to 2 feet, and the energy is weak, often below 200. The winds are variable, mostly cross-off or offshore, keeping the surface clean, but the lack of power is the main story. There’s a bit of a bump on Friday, August 7th, with a 2 foot swell from the west and a 13-second period. The combined energy climbs back to 294, and we’ve got a gentle offshore wind. It’s a glimmer of hope, but not a classic.
The real standout, the only one I’d really point you to, is Saturday, July 25th. The combination of a 3 foot WSW swell, groundswell period, and offshore winds will give you the best chance at a clean, fun wave. The crowds are noted as “sometimes” there, so it’s worth an early paddle.
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.
