The Lowdown
Alright, Rusty here again. Look, this 16-day stretch at Coastguard Beach is pretty grim. From the start, it’s a long run of poor surf with no real recommendations. There’s a big gap of flatness, so don’t get your hopes up. Forecasts can change, but right now it’s a dry spell.
Kicking off on Thursday, July 30th, we’ve got a weak 3ft swell from the NE, with a short 6-second period and a messy cross-shore wind at 20 km/h. Combined energy is weak at 128. Water temp is 69°, average for the season.
Friday, July 31st, offers the only real chance: Friday afternoon goes glassy with a tiny 1ft swell from the SE and a 9-second period. Combined energy is just 59. It’s clean, but you’ll be hunting for anything rideable—this is not a standout.
From Saturday, August 1st, through mid-August, it’s flat or nearly flat. Swells barely hit 2ft, periods are short, and combined energy drops to single digits or low tens. Winds are all over the place, but there’s no power behind anything. For a beginner spot like this, a swell over 5ft would be too much, but we don’t even sniff that.
The closest to a highlight is Saturday, August 8th, with a 2ft swell from the SSE at 7 seconds, combined energy of 38, and a gentle cross-shore. Still not a standout.
Monday, August 10th, has a glassy 1ft wave, but it’s barely a bump. By Wednesday, August 12th, swell drops to 0.3ft, and the wind turns onshore and choppy. Honestly, this setup is more for kite surfing than paddle surfing.
No standouts. The best bet is that glassy Friday afternoon on July 31st, but keep the expectations low. For a SE-exposed beach break, we’re just not getting the goods.
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.
