The Lowdown
Hey, Rusty here. Let’s break it down – and I’m not gonna sugarcoat it. We’ve got a tough stretch ahead with no real waves to speak of. The only spot in the mix is Coastguard Beach, and it’s just not delivering. Water temp is about 69°F, which is normal for this time of year.
Starting Sunday, September 6th, the morning is a write-off. You’re looking at a 4ft swell from the NE with a short 7-second period and a 19 mph cross wind from the NNE – lumpy and ugly. The combined energy is weak at 134. The afternoon cleans up a bit with a lighter 6 mph NW cross-off breeze and 3ft swell from the NE, still 7 seconds, combined energy at 101. It’s surfable but nothing special.
Monday the 7th, the swell drops hard – 1ft in the morning from the ENE, 9-second period, combined energy at 38. Wind is 12 mph cross-off from the NNW, so it’s clean, but there’s almost nothing to ride. The afternoon turns glassy with a 3 mph SW wind and 1.0ft swell – pretty but empty.
From Tuesday the 8th all the way through Thursday the 17th, we’re in a long, dead spell. Swell is tiny, often under 2ft, and the combined energy is mostly single digits. Winds vary from fresh cross-off to strong cross-on, but none of it matters because there are no waves. That’s a solid 10-day gap with no recommendations.
Friday the 18th brings a little pulse – 3ft NE swell in the morning with a short 5-second period, combined energy at 65, but the wind is onshore from the ESE at 6 mph, so it’s messy. The afternoon stays poor with 3ft from the NE, 6-second period, and 72 combined energy, but it’s cross-on and choppy.
The final weekend, Saturday the 19th and Sunday the 20th, offers nothing. Swell stays under 2ft, combined energy in the 20s and 40s, and the winds are cross or cross-off – clean but totally lacking in size and power.
When Coastguard Beach is this flat for this long, it’s not unusual for the area – these dry runs happen. Forecasts can change, but for now, don’t bother waxing up. There is no good surf in this 16-day window.
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.
