The Lowdown
Alright, let’s get into it. The forecast’s looking pretty flat for Coastguard Beach for a while. The first proper surf window doesn’t really show up until around September 9th, but even then it’s nothing to write home about.
Right now, through the end of August and into the first week of September, we’re dealing with tiny, weak pulses. Swell heights are mostly in that 0.3 ft to 2 ft range, with energy readings all under 100 (just 6 to 49), so it’s basically a lake out there. The wind is often cross-off or even glassy, which would be nice if there was any wave to ride, but there isn’t. The water temp is sitting at 69°F on August 25th, which is about average for this time of year.
We’ve got a long stretch of days with nothing recommended. From August 25th right through to September 8th, it’s a total write-off. Every single session is marked as poor surf conditions. You’d be better off checking the kite gear if you’re desperate to get on the water, because the waves are just not there for paddling.
The only faint glimmer comes on September 9th – Wednesday morning. The swell bumps up to 2 ft from the east, with a period of 9 seconds. The combined energy finally cracks into triple digits at 120 (moderate), so there’s a bit more push. The wind is cross-off from the northwest at 12 mph, which will keep it reasonably clean. It’s a beginner-friendly spot, consistent, but with these tiny waves, it’s only going to be fun for a longboard or a foamie. The afternoon on the 9th drops back to 2 ft but the wind goes cross-shore, so it’s less clean.
Honestly, if you’re tied to this stretch of coast, the September 9th morning is your best bet, and it’s not a standout. The rest of the 16-day window is a blank. For Coastguard Beach, this kind of flat run is pretty normal. It usually doesn’t stay this way forever, but for now, it’s a waiting game.

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. If you surf the same spot (Coastguard 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 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.
