The Lowdown

Alright folks, Rusty here. Let's have a look at what Big Beach has in store for us over the next couple of weeks.

It's a bit of a slow cooker of a forecast. The whole period kicks off with some decent, clean surf, but it takes a bit of a nosedive before any real energy returns. The first couple of days, Friday the 4th and into Saturday the 5th, are good. We're looking at a solid 5ft of south swell with those 12-13 second intervals and a moderate offshore breeze. The wave energy is moderate at 690-747 (combined energy). It's clean, moderate offshore and clean, which is a big plus. It'll be a bit of a wet one on Sunday the 6th with a risk of thunderstorms, but the surf holds in at 5.6-5.9ft, still clean and cross-offshore.

Now, here's the bit to keep an eye on. Monday the 7th is where it gets interesting for the more experienced crew. The swell jumps up to 7.5ft with a 14-second period, and by Monday afternoon it's hitting 10ft with a 15-second period. That's a powerful groundswell with strong to very strong wave energy (2937-4884 combined). The wind is light cross-shore, which is alright, but at that size, it's for experts only. It's too big for beginners.

After that, it drops like a stone. Tuesday the 8th sees us down to 3.3ft, and then from mid-week onwards the swell disappears into a hole. We're looking at a real dry spell from Thursday the 10th all the way through to Monday the 14th. We're talking about knee-high dribble with 1ft to 2ft swells. Very poor stuff.

There is a light at the end of the tunnel, but it's a promising one. Friday the 18th and Saturday the 19th are the real standouts for the second week. On Friday morning the 18th, we get a clean 3ft of SSW swell with a 16-second period, light offshore wind and wave energy building to 722 (combined). It's clean and glassy. Saturday the 19th morning looks similar, with 2.3ft of SW swell and light winds. It is not huge, but after that flat spell, it'll feel like a gift and the conditions should be pristine. This is the one to pencil in.

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.
