The Lowdown

Right then, let's have a look at what's on the table for Big Beach over the next couple of weeks. The water's sitting at a warm 81° which is right on the money for this time of year, nothing weird going on there.

We're looking at a bit of a slow start. The surf's pretty tiny through the first few days, with waves barely scraping 2ft and moderate energy levels around 243. It's clean enough but there's no real punch to it. Monday the 24th and Tuesday the 25th are more about a paddle than a proper surf, to be honest.

Things start to wake up on Wednesday the 26th. That morning we've got 2ft from the SSW with a 15 second period and a gentle offshore breeze. The energy's building, hitting 372. By the afternoon it's a touch bigger at 2ft with a 17 second period, the same clean offshore wind, and energy's climbing to 551. This is your first real standout. It's not big but that long-period groundswell is going to give you some decent shape and longer waits between sets, so you won't be fighting for every wave.

Thursday the 27th keeps things going. Morning sees 3ft from the SSW with a 16 second period, light cross-off wind, and energy is solid at 948. That's a lot of push for that size. The afternoon swings to the S at 3ft with a 16 second period and clean offshore conditions. This window from Wednesday the 26th through to Friday the 28th morning is the pick of the first week. The waves are small but the quality is there.

Now, there's a bit of a lull from the weekend. Saturday the 29th drops back to 2ft and the energy falls away. Sunday the 30th is tiny at 2ft. Monday the 31st and Tuesday the 1st of September are very average, with some sessions getting a solid score but overall energy's down. Wednesday the 2nd gives a fleeting glimpse of hope with 3ft from the SSW and 16 second period, energy at 499, but the cross-off wind isn't as clean as we'd like. After that, it drops right off again until the following weekend.

The real hero session, the one to circle on the calendar, is Monday the 7th of September. That morning it's glassy – absolutely dead calm – with 3ft from the SSW and a 15 second period. Energy's sitting at 430. That's going to be as clean as it gets. The afternoon holds the same. If you can only get in the water once over this whole run, that's your window. The Tuesday the 8th has a 3ft WSW swell with a 13 second period and light cross-off breeze, energy at 438, which will be fun but not quite as perfect as that glassy Monday.

Look, for a spot that's very consistent like Big Beach, it's been a bit frustrating in the middle there. But that first Wednesday and that Monday the 7th are worth the wait. Keep an eye on the forecast, it won't be poor forever.

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.
