G’day, I’m Rusty. Let’s have a proper look at what’s coming up.
Alright, truth be told, we’ve got a pretty bleak stretch ahead. The whole 16-day window is a tough one for surfers, with just about every session showing poor surf conditions. The only break on the radar is Coastguard Beach, and it’s not really delivering anything worth getting excited about. For the first few days, from Monday 13 July right through to the middle of the month, we’re looking at tiny swell – barely 0.3 ft at best, with short, weak periods. The wind is mostly cross or cross-off, but the wave energy is pitiful, sitting at just 3 or 4 (combined energy of all swells directed here). It’s a beginner-friendly spot, consistent, but there’s just no wave to work with. The water temperature is about average for the time of year.
We do get a slight lift around Wednesday 15 July, with a little 1 ft swell from the south, and the wind goes glassy in the afternoon. That’s about as good as it gets, but the period is a short 6 seconds, and the energy is still weak (20). It’s clean, but tiny. Same story continues through the week – a few 2 ft to 3 ft pulses, but the periods are short, and the wind is often fresh or strong. The biggest energy reading we see is 104 on Tuesday 21 July, from a 2 ft swell with a long 11-second period, but it’s still labelled as poor surf. The wind is cross-off, so it’s clean, but the swell is just too small to make it worthwhile.
Honestly, there’s no standout session here. The whole period is a write-off for decent waves. Coastguard Beach is a consistent spot, so this kind of flat run is a bit of a bummer, but it happens. If you’re desperate for a paddle on a longboard, the glassy Wednesday 15 July afternoon might give you a few ankle-biters. Otherwise, I’d give it a miss. The wind and swell just aren’t lining up. For kite surfers, the stronger breezes and small, choppy seas might offer a bit of fun, but for paddle surfing, it’s a hard pass.
Stay patient, mate. The surf will come back.
Rusty.

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 Coastguard 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.
