The Lowdown
G’day, I’m Rusty, and I’ve been staring at this forecast for Coastguard Beach for a while now. I hate to be the bearer of bad news, but honestly, this one’s a tough pill to swallow. The whole 16-day window, from the 21st of July right through to the 5th of August, is looking like a write-off for surf. There’s no standout day, no sneaky window, nothing that’s going to get a surfer out of bed. It’s a real dry spell.
The water temperature is sitting at 66°F, which is about 1°F cooler than average for this time of year. Nothing crazy, just a little on the nippy side, but it’s not the temperature that’s the problem.
Let’s walk through it. The first few days, starting Tuesday the 21st afternoon, we’ve got a weak swell from the SSE at 4 ft, but it’s a short, choppy 5-second period with a cross-shore wind. The combined energy is a measly 53 (weak). It’s just messy. Wednesday the 22nd offers a bit more size—5 ft from the S—with a slightly better 8 to 9-second period and manageable cross-offshore winds, but the energy is still only moderate (321-389). The problem is the “poor surf conditions” tag sticks on every single session. Nothing cleans up enough to make it worthwhile.
Thursday the 23rd sees the swell drop to 2 ft, and by Friday the 24th we’re down to 1 ft. The wind is onshore or cross-onshore, creating chop. The combined energy plummets into the teens and twenties. It’s a total flat spell. This pattern of tiny, weak swell with poor wind continues right through the weekend and into the next week. The 28th of July has a brief moment with a 4 ft SSE swell and a 9-second period, and the energy climbs to 258 (moderate), but the wind is a fresh cross-shore with lumpy chop. The 30th of July shows a similar story with 3 ft and 208 energy, but again, the wind is a fresh cross-offshore, which is clean but the swell is just too small and weak for a proper wave.
For the entire forecast, the swell rarely breaks 3 ft, and when it does, the period is short. There’s no groundswell, no long-period energy. The wind is almost always either cross-shore, onshore, or too strong. The break is consistent, which is a small mercy, but the quality is just not there. A beginner might find a tiny, crumbly wave on a clean morning, like on the 4th of August with a 1 ft SE swell and a light offshore wind, but it’s not going to be a memorable session.
So, what’s the call? There’s no standouts. The best you can hope for is a vague, underwhelming window on the 28th or 30th of July, but even then, it’s marginal. For an area that’s usually consistent, this is a lean run. The one good thing is that Coastguard Beach is a consistent spot, so it tends not to stay this poor for long. Forecasts can change, but right now, I’d save the wax and wait for a better swell. There’s nothing here for anyone.
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.
