The Lowdown

Alright folks, Rusty here. Let’s have a look at what Big Beach has cookin’ for the next couple of weeks.

We’ve got a slow start, but it’s not a total washout. The first few days are small, but there’s a real pulse building later on. The water temp is sitting at 80°, which is pretty much bang on average for this time of year, so no surprises there.

The first real action kicks off on Thursday, July 16th. Thursday morning sees some clean 2ft swell from the west, with a light E breeze keeping it cross-off. The energy’s moderate (494), and it’s a nice little starter. Thursday afternoon stays similar, 2ft from the SSW, still clean. Friday the 17th is more of the same – 2ft from the west in the morning, clean, but nothing to write home about. The afternoon gets a bit windier (12 mph), and the quality drops.

The weekend’s a bit of a write-off. Saturday the 18th is small and clean in the morning, 2ft, but it gets chopped by a 16 mph E breeze in the afternoon. Sunday the 19th is average, with 2ft swell and a bit of offshore wind in the afternoon, which is nice, but the size is tiny.

Now, Monday the 20th is where things start to look up. Morning sees 3ft from the south, with a light E breeze and moderate energy (505). The afternoon goes offshore with ENE wind at 12 mph, and that 3ft S swell will be clean. This is a solid option for the week.

The real standout, though, has to be Thursday, July 23rd, into Friday, July 24th. Thursday afternoon is a gem – 3ft from the SSW, with a 20-second period, and a clean offshore ENE wind. The energy is strong (773), and the conditions are set up for some proper, lined-up waves. Friday morning holds similar quality – 3ft from the SSW, offshore wind, and strong energy (773). This is the best of the forecast. The 20-second period means it’s a groundswell, so expect long, clean walls and good gaps between sets. It’s a point-break style wave, and Big Beach is fairly exposed, so it should handle it well.

Then Saturday, July 25th, morning bumps up to 3ft from the south, with a very long 19-second period and very strong energy (1116). That’s a heap of power. The wind is light ESE, so it’ll be clean. This is another big opportunity, but with that much energy, it’s getting into the expert zone. The afternoon gets a bit windier, but still offshore.

The second week sees the swell taper off. Sunday the 26th through Tuesday the 28th still has some clean 3ft to 2ft waves, but the energy drops. By Wednesday the 29th, it’s back to 2ft, and the quality fades. The last few days of July are small and weak, with energy dropping below 100, so it’s a flat end to the run.

Keep an eye on the 23rd and 24th – that’s your window. Maybe a few crowds on the sandbanks, but it’s worth it.

Stay stoked,
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.
