The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Coastguard Beach.
First up, the water temp is sitting around 68°, which is about 2° warmer than average for this time of year. That’s a little above normal, but nothing too wild.
To be honest, the next 16 days are a real struggle. There’s a big gap of nothing worth paddling out for from now until the afternoon of Sunday the 6th. Even then, it’s not great. The first real chance to get wet is Sunday afternoon the 6th, with a tiny 3ft swell from the NE, period of 7 seconds. The wind is light and cross-offshore, so it’ll be clean, but the energy is weak (104). It’s surfable, but very ordinary.
The best on offer is a bit of a stretch, but if I had to pick one standout, it’d be Monday morning the 7th. The wind is offshore from the W at 6 mph, so it’ll be clean. But the swell is tiny, only 2ft from the NE with a period of 9 seconds. The energy is very low (72). It’s a beginner-friendly wave, but nothing to get excited about. That’s about as good as it gets.
The second week is a write-off. There’s a pulse of energy mid-week around the 17th, with a 7ft swell from the ENE and a period of 8 seconds. That’s hitting 561 combined energy, which is strong, but the wind is onshore from the ESE at 12 mph, making it messy. Plus, that’s only for experts. For most of us, it’s a no-go.
Overall, the consistency is there, but the quality isn’t. For a beach break like this, the wind and swell direction don’t line up for good surf. It’s one of those times where the forecasts could change, so don’t write it off completely, but right now, it’s a lot of waiting for very little reward.
Rusty.

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

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.
