Table - best surf conditions forecast for Diamond Beach over the next 16 days.
Right, let’s be straight with you. This is a rough one for the next couple of weeks. Honestly, there’s nothing in the 16-day window that’s really worth paddling out for. The only break we’ve got data for is Diamond Beach, and it’s just not cooperating.
The pattern is basically flat and messy. We’ve got a long gap of poor surf from now all the way through to the end of July. The first real sniff of anything comes on the 20th of July, Monday morning, but it’s a far cry from good. You’ll see a tiny 3 ft swell from the south, with a period of 7 seconds – that’s short period, windswell stuff, not the kind of wave you want to drive for. The wind is offshore from the NW at 6 mph, so it’ll be clean, but the combined wave energy is barely there at 83 (weak). The water is running a touch warmer than normal for the time of year, about 75°, which is nice, but it doesn’t help the waves. It’s an inconsistent spot anyway, so this blank run is more normal for the area than a surprise.
The 21st of July Tuesday morning is a similar story: 3 ft from the SSE, 8-second period, light cross-shore breeze, but the energy is still weak at 80. The surf is just too ordinary to get excited about.
The 22nd of July Wednesday brings a bit more energy, with the combined swell energy hitting 122 (moderate) in the morning, but the swell is still under 3 ft and the wind is cross-shore, making it choppy. Not a winner.
The 23rd of July Thursday is the biggest swell we see, with 4 ft to 5 ft from the south, but the period is only 7 seconds and the wind is cross-onshore at 12 mph, so it’s going to be a bumpy, messy mess. The energy climbs to 212 (strong) in the afternoon, but with that onshore wind and short period, it’s more of a kite-foiling setup than a proper surf day. This is a beach break, and with that wind, you’d be fighting it the whole time.
The 24th and 25th of July see the swell ease back, with onshore winds keeping things choppy. The 26th of July is a similar story, dropping back to tiny surf.
So, bottom line: there is no standout, no session worth chasing. The whole 16-day period is a write-off for quality surf. For a beginner, it might be a paddle, but for anyone wanting a real wave, you’re better off waiting for the next forecast. The forecasts can change, but right now, it’s a hard pass.

Information about the Diamond Beach Surf forecast
The above surf forecast table for Diamond Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Diamond Beach can be found by selecting the local surf guide option on the grey menu. Our Diamond 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 (Diamond 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 Diamond 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.
