The Lowdown

Gather 'round, crew. Rusty here. We've got a 16-day window on Big Beach, and I gotta be straight with you – it's a long, quiet stretch with only a few bright spots scattered in. The first good waves don't show up until Friday the 28th of August, so there's a bit of a wait if you're itching for a session right now. After that, there are several gaps of days with nothing worth paddling out for, so pick your moments carefully.

The water's sitting at a pretty typical 81°F for this time of year, so a spring suit is just dead weight.

The standout session is Friday morning, the 28th of August. We've got a clean 2ft swell from the S, with a 14-second period – that's quality groundswell, bringing some real push. The ENE wind is light and offshore, 9 mph, meaning the surface will be glassy. The combined energy is moderate, sitting at 339, so there's enough juice to get a few fun ones. Big Beach is a beginner-friendly spot being very consistent, but with the 2ft and offshore conditions, it'll be user-friendly for all levels. The morning is your clear winner.

Friday afternoon, the 28th, holds up okay too. The swell is the same 2ft from the S, but the wind picks up to 12 mph from the NE, still offshore. It'll be a bit bumpier than the morning, but still a solid option. The combined energy is a touch higher at 390, giving it a little more grunt.

Then we hit a dry patch. Saturday the 29th and Sunday the 30th are write-offs. The swell drops to 2ft or 2ft, with cross-off winds and poor form. It's not worth the effort.

Monday the 31st of August morning brings a little hope back. The swell is small at 2ft from the SW, but the wind is clean offshore from the ENE at 12 mph. The period is a very long 15 seconds, which is a deep groundswell, but at a beach break like Big Beach, that long period can make it break a bit too straight. The combined energy is moderate (274), so you might find a few lined-up runners if you're patient. The afternoon, however, is a no-go with cross-off winds and a 19-second period – just too straight and weak.

Tuesday the 1st of September sees a slight bump in swell height to 3ft from the SSW, with a very long 18-second period. The combined energy jumps to 486 (moderate), but the cross-off winds from the ENE keep it from being clean. It's a marginal call – the energy is there, but the shape will be tricky.

Wednesday the 2nd of September offers the biggest swell of the early period: 3ft from the S, with a 16-second period. The combined energy is a solid 529. But the wind is cross-off from the E, and there are rain showers making conditions messy. This is a "maybe" for the determined surfer, but it's not going to be a picture-perfect session.

Thursday the 3rd of September morning is your next real bet. The swell is 3ft from the S, period 14 seconds, and the wind is back offshore from the NE at 9 mph. The combined energy is 281 (moderate). This is a clean, fun morning. The afternoon is similar with a slightly stronger offshore wind.

After Thursday the 3rd, the second week is a tale of small, inconsistent swell and wind issues. Friday the 4th and Saturday the 5th of September are surfable but very ordinary – 1ft to 2ft, with offshore winds but very weak energy. The combined energy drops into the 100-200 range. It's ankle-snappers, not really worth a dedicated trip.

From Sunday the 6th of September through to the end of the forecast on Saturday the 12th, the pattern is poor. Swell stays tiny (2ft to 2ft), winds are often cross-off or fresh onshore, and the combined energy is weak to moderate. The session on Monday the 7th of September has a 2ft swell from the SSW with a 15-second period and fresh offshore winds, giving a combined energy of 378 (moderate), but the swell height is just too small to make it exciting. Tuesday the 8th of September has a 3ft SSW swell with a 16-second period and a combined energy of 576 (the highest of the whole period), but the cross-off winds and poor surf conditions kill it. By Thursday the 10th of September, the wind swings onshore from the SSE, turning the ocean into a messy chop – that's a definite stay-on-land day.

Bottom line: If you can get out Friday morning, the 28th of August, you'll get the best of it. The rest of the 16 days is a mix of marginal, inconsistent, and small surf. The conditions look more interesting for a kite than a surfboard on many of the afternoons. Keep an eye on the forecast, but don't hold your breath.

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.
