The Lowdown

Alright, Rusty here. Let’s have a look at the stretch ahead for Big Beach.

The good news is this spot is very consistent, so we’ve got waves almost every day. The bad news is it’s a beginner-friendly beach break and the swell is small for most of the run. The best of it is a bit further out, so keep your expectations in check for the first week.

Starting from Sunday the 19th, it’s really small – only 1ft to 2ft of south swell. The combined energy is weak at 202, and the wind is a cross-off. It’s clean, but barely surfable. Monday the 20th picks up a little to 3ft with a south swell, period around 16 seconds, so there’s some long-period groundswell in the mix. The energy is moderate (495), and the morning is clean with a light breeze. Not a standout, but a fun little longboard morning if you’re desperate. Tuesday and Wednesday stay similar, with the swell dropping to 2ft on Wednesday, but the period jumps to 24 seconds – that’s a very long period groundswell. The energy is moderate to strong (645), but at that size, it’s more of a gentle pulse than a proper wave. The cross-off wind keeps it tidy.

Thursday the 23rd through Saturday the 25th see the swell hold around 3ft to 3ft, but the wind is a moderate cross-off and the conditions are described as marginal. The energy is moderate to strong (up to 825), but the quality isn’t there for paddle surfing. Honestly, with the consistent cross-off and small beach break, this setup looks more interesting for kite surfing than paddle surfing.

Now, here’s the first real standout. Sunday the 26th into Monday the 27th: the wind turns offshore, light from the NE at 6 mph, with 3ft of SSW groundswell. The period is around 15-16 seconds, so the waves have shape, and the energy is moderate (around 473). The offshore wind will clean it right up. This is the best spell of the first week. The water temp is about 80°F, which is normal for the time of year.

The middle of the week (Tuesday 28th to Wednesday 29th) is ordinary – small, cross-off, and the scores are low. Thursday the 30th afternoon sees a slight improvement with a 2ft SW swell and a period of 18 seconds, offshore wind, and good energy (330). It’s clean, but still small.

The real standout of the whole outlook is Sunday the 2nd of August. The morning brings 4ft of SSW swell, period 16 seconds, and a light cross-off breeze from the east at 6 mph. The combined energy is strong at 708, and the forecast says “expect very good surf conditions.” This is the biggest swell of the run, and the wind is light enough to keep it clean. For a beginner-friendly beach break, 4ft is the sweet spot. This is the one to circle on the calendar.

Monday the 3rd of August holds 3ft in the morning, dropping to 3ft in the afternoon, with offshore wind and moderate energy. A solid tail end to the run.

Crowds are possible at Big Beach, as it’s a popular spot, but with the small sizes for most of the run, it shouldn’t be too hectic.

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.
