The Lowdown
Alright, grab a coffee, sit down, and let me tell you what’s happening at Coastguard Beach over the next couple weeks. Spoiler: it’s grim. This stretch is locked in for a nearly 16-day lull with no surf worth paddling out for. The whole period is plagued by onshore and cross-shore winds, weak swell energy, and consistently poor surf quality. Every single session gets a score of zero, so there’s no standouts, no hidden gems.
The first few days are a write-off. Sunday the 26th has a cross-on NE wind at 15 mph making a sloppy, choppy mess of 4ft ESE swell with only 167 combined energy. Monday and Tuesday are smaller and weaker, with onshore or cross-shore breeze keeping everything flat and ugly. Into Wednesday and Thursday the energy picks up slightly, the 30th of July shows 5ft ENE swell with combined energy jumping to 244 and then 359, but it’s under a fresh cross-onshore NE wind at 19-22 mph. That’s not surfable; that’s just a windblown lump. By Friday the 31st, the swell drops back under 3ft.
Through the first week of August, conditions don’t improve. We get a mixed bag of glassy mornings and gentle offshore winds on the 4th, 5th, and 6th, but the swell heights are tiny—1ft to 2ft—and the combined energy is barely reaching double digits. On the 4th there’s a glassy 2ft SSE swell at 8 seconds in the morning, but it’s puny and powerless. The 7th shows a brief pulse of 4ft S swell in the afternoon with 187 combined energy and light cross-shore wind, but still, the quality is rated poor. The rest of the run through to the 10th is tiny, cross-shore, and not worth a second look.
The water temperature is 68°F with a normal anomaly of 1°, so nothing unusual there. For beginners, don’t even bother—the only consistent thing here is poor conditions. For the experienced crew, there’s nothing for you either. If this were a beach setup, you might think about kiting, but it’s just not happening.
Hang tight. Forecasts change.

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.
