The Lowdown
Alright, Rusty here again, talking in feet and degrees.
It’s been a rough run at Coastguard Beach. The whole 16-day window starts with a big gap of nothing good. The first few days are tiny, messy, and not worth getting wet for. You’re looking at a solid week of junk before any real wave shows up.
The one spot worth circling on the calendar is the morning of Thursday, 23 July. That’s the standout. We’ve got a 4ft SE swell, with an 11-second period, and the wind is clean offshore from the W. That’s gonna make for some clean, fun lines. The combined energy is 235 (moderate), so there’s enough juice to get a few turns in. For a beginner spot, this is a good size, and the offshore wind will keep things smooth. Water temp is about 67°, which is normal for this time of year.
After that, it’s back to small stuff. The Friday morning, 24 July, is glassy but very weak – 2ft, 8-second period, energy of only 66. It’s rideable on a log, but barely. Then from Saturday 25 July onward, it’s a long stretch of tiny, underpowered surf, mostly under 2ft with short periods. The wind is often clean or cross-off, but there’s just no swell to work with.
The final week has a few glassy moments, like the morning of Friday, 31 July, but with 1ft and 6-second period, it’s barely a ripple. Energy is 19. It’s more of a float than a surf.
Bottom line: the only real surf day is Thursday morning, 23 July. That’s your best bet. The rest is a long, flat spell with a few clean but tiny waves. If you’re keen, Friday 24 July morning is glassy, but it’s weak. After that, you’re waiting again.
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. 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.
