Alright, this is Rusty.
Look, I’ve gotta be straight with you – for the next couple of weeks, Coastguard Beach is in a proper slumber. The entire 16-day window is a flat spell with nothing worth paddling out for.
We start with Sunday the 12th through to Monday morning the 13th: tiny, messy 0.7ft from the south, with a short 7-second period. The combined energy is a measly 5–6 (weak), and the 6 mph ENE wind is cross-onshore, making for poor surf. It’s a write-off.
From Monday afternoon through to Thursday morning the 16th, the swell drops even further to 0.3ft, with combined energy values between 3 and 9. Even when we get some clean, offshore winds early Thursday morning (WNW at 12 mph), there’s just nothing there to ride – zero energy.
Things stay dead through the weekend and into the next week. The strongest push we see is on Tuesday the 21st, when a 4ft south swell tries to show up, but the period is a weak 5 seconds, and the combined energy only hits 87 (still moderate-low). The wind is cross-on from the SSE at 9 mph, keeping the surface fairly choppy. Not good.
From Wednesday the 22nd onwards, it’s back to small, short-period junk: 2ft to 3ft from the SSE and ESE, with periods of 4 to 7 seconds. Even though the winds turn cross-off and clean, the swell energy is in the low double-digits (28 to 44), meaning weak, gutless waves.
Honestly, there’s not a single standout session in this whole stretch. If you’re desperate, you might find a tiny knee-high wobble on Wednesday the 22nd or Thursday the 23rd when it’s clean, but it’s beginner-only stuff. Otherwise, save your energy. Forecasts can always shift, but right now, this beach is on a total holiday.
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.
