The Lowdown
Howdy, it’s Rusty. Let me tell ya, the next 16 days at Coastguard Beach are looking pretty grim. We’re talking “poor surf conditions” across the board, and the combined wave energy barely hits 63 (weak energy) on its best day. No real swell to speak of. The water temp is 67°, which is pretty average for this time of year, so nothing weird there.
Monday the 7th kicks off with a tiny 2ft swell from the ENE, period 9 seconds, and a cross-off wind from the NNW at 12 mph. The afternoon goes glassy, wind drops to zero, but the swell is already down to 1ft. It’s clean, but there’s no power. Tuesday the 8th is even smaller, 0.7ft, with messy wind. Wednesday the 9th has a little bump from the south, but it’s a 3-second windswell – short and weak, with a cross-shore wind hitting 19 mph. That’s more of a kite-surfing day. Thursday the 10th goes flat, 0.3ft, just clean and useless. Friday the 11th has a glassy moment again, but still only 1.0ft. The rest of the run is all the same – tiny swell, lumpy cross-shore winds.
There’s no standout. The best I can offer is Monday afternoon the 7th, with glassy conditions, but you’re on a 1ft, 9-second swell. It’s a beginner spot and consistent, but you’ll be fighting for tiny waves. Crowds are possible, but with this little swell, it’ll be quiet. The swell direction is ENE, but the break likes SE, so it’s never really right. The rest of the two weeks is a flat, windy gap. Don’t bother.
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.
