Table - best surf conditions forecast for Big Beach over the next 16 days.
Alright folks, Rusty here. Let’s get into it. We’ve got a long-range look at Big Beach, and it’s not an instant classic, but there’s a real standout hiding in the second week.
The overall pattern is a slow burn. The first few days are pretty lackluster with small, weak swell and not much punch. The combined swell energy is weak to moderate at best, sitting around 319 (moderate) on the opening Sunday morning, then dropping even lower through the middle of the week. You’ll see some 2ft waves rolling in from the SW, but the period is a juicy 15 to 16 seconds for a groundswell. That long period will give you some shape, but the size is small, so it’s more of a longboard or funboard game. The water temp is about average for this time of year, so no surprises there.
Monday the 13th shapes up as the best of the early days. The wind goes light offshore from the NE in the morning, and that combo of 2ft, 15-second SW groundswell with clean conditions is about as good as it gets for the first week. The energy is low (267), but for a beginner-friendly spot like Big Beach, it’s a nice, gentle introduction. Crowds are sometimes a thing here, so you might have company.
Now, don’t get too excited about the middle of the week – Tuesday through Thursday (14th to 16th) is just okay. The swell stays small, around 2ft to 2ft, and the wind is mostly cross-offshore. It’s clean, but not worth writing home about. The combined energy does jump up a bit on Wednesday the 15th (544), but the swell direction swings to the W, which isn’t the optimum for this spot. The waves are surfable, but nothing special.
Then we hit a bit of a lull. From Friday the 17th through to Monday the 21st, the swell drops to 1ft to 2ft, and the energy is weak. There are some offshore winds on Monday the 20th, but the waves are small and inconsistent. A few days of ordinary surf.
Hold on to your board, because Wednesday the 22nd is where it starts to get interesting. The swell picks up, and the combined energy starts to climb seriously. On Wednesday morning, the energy is 656 (moderate), but the real fireworks begin on the 23rd of July. Thursday the 23rd is a standout. The swell hits 3ft from the SSW, with a 20-second period – that’s a proper groundswell, very long period. The combined energy is 911 (moderate to strong), and the wind is offshore from the ENE. That’s clean, lined-up waves, and the long period will make the paddling easier between sets. This is the best day on offer, hands down.
Friday the 24th and Saturday the 25th keep the momentum going. The swell builds to 3ft and then 4ft, with the energy going through the roof. Saturday afternoon the 25th shows a combined energy of 1092 (strong) – that’s a lot of power. The wind is offshore from the NE, and the waves are clean. This is expert territory for sure – over 4ft with that much energy, it’s a step up from the beginner-friendly early days. The long-period groundswell (19 seconds) will be breaking a bit straight on a beach, but the offshore wind will hold it together.
Sunday the 26th and Monday the 27th are still good, with 3ft to 4ft SSW swell and offshore winds, but the energy is dropping off a bit. It’s a solid end to the run.
To sum it up: the first week is small and clean, but the real winner is the second week, especially Thursday the 23rd and Saturday the 25th of July. That’s when the groundswell and offshore winds align for proper, powerful waves. If you’re an experienced surfer, those are the days to circle. Beginners will have fun on the smaller days around the 13th.
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.
