The Lowdown
Alright, Rusty here again. Let me level with you: the next 16 days at Coastguard Beach are a total bust. No good surf to speak of. We’re looking at a long stretch of flat, blown-out, or just plain poor conditions from start to finish.
Monday, 3rd August kicks off with some swell—a 6ft S swell with a short 6-second period and moderate energy (256). But the wind is screaming at 31 mph cross-off, near gale. It’s clean but way too windy. The afternoon brings a 6ft S swell with a 9-second period and stronger energy (538), but still 28 mph wind. This is more of a kite-surfing scene than a paddle surf one.
Tuesday, 4th August, we drop to a tiny 2ft SSE swell with weak energy (47). The morning has a nice offshore wind from the W, but there’s just nothing to ride. Water temp is 67°, which is a bit cooler than normal for this time of year.
From Wednesday, 5th August, all the way through to the end of the 16-day window, it’s flat. Swell heights rarely break 2ft, periods are short, and energy is in the single digits or low double digits. The wind switches around, but it doesn’t matter—there’s no surf.
The only small pulse comes Thursday, 13th August, with a 4ft E swell and a 6-second period, moderate energy (116). But the wind is cross-on from the ENE, so it’ll be choppy. Still, it’s rated as poor surf conditions.
Bottom line: don’t bother. The board can stay in the garage. Sometimes these blank runs happen, and this is one of them. Forecasts can change, but right now there’s nothing to chase.
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.
