The Lowdown
Alright, I’m looking at the charts for the coming weeks, and I’ve got to be straight with you—it’s slim pickings. The only spot on the radar is Coastguard Beach, and it’s a stretch to call it a proper surf window. We’ve got a consistent, beginner-friendly beach break sitting exposed to the southeast, with a west-northwest offshore wind direction that would clean it up if there was any swell to work with. But the numbers just aren’t there.
The water temperature is sitting at 67°F, which is about average for this time of year—nothing crazy there.
We kick off on Sunday morning, August 2nd, with weak, tiny swell. A 0.7 ft ESE swell at 7 seconds—barely a ripple. The combined energy is a measly 7 (weak energy), and with a cross wind, it’s messy. Conditions are poor all the way through the rest of that day and into Monday morning. Monday afternoon on August 3rd sees a jump to 6 ft from the south at 8 seconds, with combined energy hitting 379 (moderate energy), but it’s still flagged as poor surf. The wind is strong cross-off, so it’s clean, but the swell quality isn’t there.
Tuesday morning, August 4th, is the only real standout in the whole 16-day run. We’ve got clear skies, a gentle offshore wind from the WNW at 9 mph, and a 2 ft SSE swell with a 9-second period. The combined energy is still weak at 61 (weak energy), but with offshore winds and clean conditions, it’s the only time you’ll get a halfway decent little wave. The water is still around 67°F, and it’s glassy enough for a fun session on a foamie or a longboard. After that, it’s a long, dry stretch.
From Tuesday afternoon on August 4th all the way through to Sunday, August 17th, the swell drops to near flat—0.3 ft to 1 ft, with periods mostly under 8 seconds and combined energy flirting with single or double digits. Winds are a mix of cross-off and light offshore, but there’s just no energy to work with. The forecast shows poor surf conditions day after day, with no real change. Even the end of the run, around August 17th, is still just tiny 1.0 ft waves with moderate cross-off breezes. It’s not going to happen.
Honestly, if you’re desperate, Tuesday morning, August 4th, is your best bet. It’s small, clean, and beginner-friendly. Otherwise, the next 16 days are a washout for surf. The good news is that this spot is consistent—it won’t stay this flat forever. Forecasts can change, but for now, leave the boards in the shed.

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.
