The Lowdown
Alright, let’s look at the next 16 days, and I’ll be honest with you – it’s a real bummer of a forecast. There’s a big gap of quiet days right at the start, with no surf worth paddling out for. About four days of barely a ripple.
The first thing that registers is on Thursday, July 30th. The swell comes up to about 3ft from the ENE-NE, but it’s a short, weak windswell with a period of only 6 seconds. The combined energy is moderate, hitting 184 on the afternoon, but the wind is a strong cross-shore, making it a lumpy, choppy mess. This is a beach break, so with that cross-chop, it’s looking more like a kiteboarding day than a surfing day. It’s not too big for beginners, but it’s not good.
After that, the rest of the run is a flat, sad story. From Friday, July 31st, all the way through to the end, every entry is “poor surf conditions” with tiny waves – mostly under 2ft. The energy is weak, often dropping into the single digits. There are a few clean moments with light offshore breezes, like on Friday, August 7th, with a 2ft swell from the S and a glassy WSW wind, and again on Sunday, August 9th, with a 1ft swell from the NE and light offshore wind. But the swell is just too small and short-period to do anything with. The water temp is about normal for the season.
In short, there’s no standout session here. No big swell, no perfect wind. This 16-day window is a total wipeout for surf. The bright side is the spot is listed as "consistent," so it doesn’t usually stay this flat for long, and forecasts can change. But for now, leave the board in the car.

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.
