The Lowdown
Alright, Rusty here, lettin' you know what's up swell-wise.
We start off Thursday the 23rd with some small but clean surf. Water temp is about 80°, pretty average for this time of year. Waves are 3 ft from the SSW with a long 20-second period, so it’s got some punch for its size. The combined energy is moderate (750). The wind is a cross-off from the East at 12 mph, so the surface is smooth. Nothing to write home about, but it’s a start.
The real standout is Friday afternoon the 24th. The swell holds at 3 ft from the SSW, still a long 17-second period, and the wind switches to offshore from the ENE at 16 mph. The combined energy bumps up to 864 (moderate), and we’re looking at very good surf conditions. Clean, offshore lines all afternoon. This is the pick of the week.
Saturday the 25th afternoon is also a winner. Same swell, 3 ft from the SSW, offshore ENE wind at 16 mph, and another very good call. Great session.
Sunday the 26th through Monday the 27th keeps the quality with light offshore winds and waves around 3 ft to 3 ft, but the energy is tailing off. By Tuesday the 28th, the swell drops to 2 ft, and conditions turn ordinary.
We hit a dry spell from Wednesday the 29th into early August. Waves shrink to 2 ft to 2 ft, and while the wind is light or glassy, there’s just not enough wave to work with. The combined energy falls into the weak range, below 200. That’s about 4 days of nothing much.
The second week stays quiet. There’s a tiny bump on Wednesday the 5th of August with a 2 ft SSW swell and offshore wind, but the energy is weak (221). Another small bump on Friday the 7th, but the wind is cross-off and conditions are only marginal.
Your best bet? Friday the 24th through Sunday the 26th of July. Don’t miss it.
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.
