The Lowdown
Alright, let’s get real about this stretch. I’m lookin’ at the whole 16-day window for Coastguard Beach, and I gotta be straight with you — it’s a tough run. The forecast shows a lot of small, weak, and messy conditions, with hardly any windows that get the blood pumpin’. The water temp is sittin’ around 66°, which is pretty normal for this time of year, no big anomaly to talk about there.
The first few days are a write-off. Tuesday morning kicks off with a tiny 2ft southerly swell, but the period is a short 4 seconds, that’s just wind chop, and the 16 mph crosswind is makin’ a mess of it. Combined wave energy is a weak 25, so there’s just no power. Tuesday afternoon is even worse — 4ft but the period is still 4 seconds, the wind is up to 22 mph cross, and the energy is only 48. That’s a no-go.
Wednesday, the 22nd, has a pulse of 5ft from the south, period climbs to 8 seconds, and the wind is a cross-off at 22 mph. The energy jumps to 314, which is a moderate number, but with that much wind, it’s gonna be bumpy and hard to enjoy. The afternoon drops right off. Thursday morning the 23rd is the first time we see a flicker of hope — a 2ft SE swell at 9 seconds, with a gentle NNW breeze at 9 mph, making it clean. The energy is 141, so there’s a little bit of push. But the comment says “surfable waves but very ordinary conditions,” and I’m only giving it a 1 out of 10. It’s small, and it’s a beach break, so you’ll be scratchin’ for something to ride.
From there, it’s a long, dry stretch. From Thursday afternoon all the way through to the end of July, there’s just nothing. A bunch of days with 1ft to 3ft, short periods, onshore or cross-onshore winds, and combined energy barely breaking 50. It’s flat, it’s chopped, it’s frustrating. Even the glassy morning on July 31st with 1ft and 10-second period — the energy is 57, but that’s too small to do anything with. That’s a long gap of about a week with no real surf.
We finally get another small chance on Thursday morning, July 30th. The swell is 2ft from the SE, period 10 seconds, and the wind is a clean offshore from the WNW at 12 mph. That’s the best wind of the whole run. The energy is 93, still weak, but it’s clean. The comment calls it “surfable but very ordinary,” and I’d agree. It’s a longboard-only kinda setup, with a very long wait between sets because of that 10-second period.
The first few days of August offer a little more consistency in size, but nothing to write home about. The 1st of August has 2ft from the south, 9 seconds, with a cross-off wind, but it’s a risk of thunderstorms, and the energy is only 89. The 2nd of August has 3ft from the ESE, 8 seconds, cross-off winds, but it’s still small. The only real standout in the whole 16 days is the morning of July 30th — that offshore wind makes it the cleanest the beach will be, but it’s still tiny. For a beginner, that might be a fun session, but for anyone else, it’s a wait.
Honestly, the best I can say is: if you’re desperate for a paddle and a few little rollers, point your board at Coastguard Beach on the morning of July 30th. Otherwise, this stretch is a blank run. The breaks are inconsistent, and it tends to stay poor in these conditions. Forecasts can change, but as it stands, leave the board at home for most of this.

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.
