The Lowdown
Alright, let's have a look at what's cookin' over at Big Beach. The water's sitting at about 80°, which is pretty average for this time of year, so no surprises there.
The overall pattern for the next couple of weeks is one of small and inconsistent surf, with a few windows where things look a bit more promising. The first few days are really nothing to write home about, with weak, small swell and onshore or cross-off winds. It's not until Monday, July 20th, that we start to see a bit of life.
The standout period looks to be from Wednesday, July 22nd through to Saturday, July 25th. The swell starts to pick up from the SSW, but the real gem is on Wednesday afternoon, July 22nd. We've got a nice, long-period groundswell coming in at 2ft from the SSW with a period of 23 seconds. That's some seriously long-period energy. The wind goes offshore from the ENE, making for clean conditions. The combined energy is up at 756 (moderate wave energy), which is the strongest we'll see for this entire period. It's not big, but that long period will give it some punch, and it should be peeling nicely. Be aware, that long period can make it break a bit straight at the beach, but with the offshore wind, it should still be fun.
Saturday, July 25th, is another good call. The morning has clean surf with a 3ft SSW swell (19-second period) and light cross-off winds. The afternoon gets an upgrade with a 3ft SSW swell, a light offshore from the NE, and a combined energy of 677. That's a good, solid session for the more experienced crew, as 3ft can be a bit much for beginners here.
After that, it trails off again. The week of July 28th onwards is pretty ordinary, with small, weak swell. There's a nice glassy morning on Thursday, July 30th, but with only 2ft of swell, it's barely worth mentioning.
So, to wrap it up: if you've got a window, target the afternoon of Wednesday, July 22nd, or the 25th of July. The rest of the time, it's either too small or too messy to get excited about. Expect crowds to be possible at Big Beach, especially on those better days, as it's a pretty consistent spot.

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.
