The Lowdown
Alright folks, Rusty here. Let’s get into it.
The next 16 days are a mixed bag. We’re not looking at any huge, adrenaline-pumping swell, but there’s a solid run of consistent, clean conditions that’ll keep you happy, especially if you’re a fan of a longboard or a funboard. The main event is a series of moderate, well-directed swells that will hold up nicely, and the wind is playing ball for the most part. There’s a bit of a lull right at the end, but the first two weeks have plenty to offer.
Big Beach is the go-to, and it’s a consistent performer. The water temp is about average for the time of year, so no surprises there. We kick off on Thursday, July 16 with a clean 2ft swell from the west, with a 14-second period, giving us nice, lined-up waves and a combined energy of 494 (moderate). The wind is a light cross-off, so the surface will be tidy. Good for a paddle. This pattern repeats into Friday, with slightly smaller 2ft swell but still clean. The real standout window starts on Monday, July 20. The swell picks up to 3ft from the south, with a 16-second period, pushing the energy to 495 (moderate). The wind switches to a light offshore on Monday afternoon, and that’s when the wave faces will be clean and picturesque. That offshore wind is a major positive. This quality continues into Tuesday and Wednesday, with similar 3ft to 2ft south swells, and the period on Wednesday morning jumps to 24 seconds – that’s a very long-period groundswell. It will bring a lot of energy (562), but it might break a bit too straight and fat at a beach break, so keep that in mind.
The next big highlight is Saturday, July 25. The morning session sees a 3ft swell from the SSW, with a 19-second period, and the combined energy hits 915 (moderate to strong). The wind is light and cross-off, so the conditions are prime. This is the best swell of the entire period. The energy is there, and the timing is good. The following Sunday and Monday, July 26 and 27, are also excellent, with a clean 3ft to 3ft SSW swell and a solid offshore wind from the NE. That’s a classic setup for clean, fun waves. Crowds are possible at Big Beach, so get there early for the best of it.
After that, the swell starts to taper off. We get a glassy morning on Tuesday, July 28, with a 2ft swell, but it's a bit ordinary. The final stretch from July 29 onwards sees the energy drop right off, with weaker swells and periods below 150 (weak). The end of the month is a quiet period, so you’ll have a few days of flatness to rest up. The forecast is solid for the first two weeks, so don’t sleep on it.

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.
