The Lowdown
Alright, grab a coffee and settle in, because the outlook for Coastguard Beach is a bit of a quiet one. We've got a long 16-day window ahead, and honestly, the surf is mostly going to be pretty lackluster. There's a big gap of nothing worth paddling out for from the start, all the way through the late summer doldrums.
From now through the first week of September, it’s a waiting game. You'll see tiny, weak swells bumping around, mostly from the east and southeast. The wave energy is in the low double digits, which is just a whisper at best early on. We're talking knee-high slop at best. The winds offer some clean windows, especially with that chilly west-southwest airflow, but with nothing to push through, it’s just flat and pretty. The water temps are hovering around 69°F, which is about average for this time of year—nothing special there.
There's a slight uptick we can talk about, but it’s nothing to get too worked up over. Around the afternoon of Saturday, September 5th, we see the energy finally climb a bit. The swell from the east hits about 2 ft with a 10-second period, giving it a bit of push, and the combined energy touches 97 – just a taste of moderate energy. Winds are light from the northwest, blowing clean cross-offshore. It’s surfable, but very ordinary. The break *might* offer a longboard wave, but don't expect any power. Keep your hopes in check.
After that brief pulse, it fades back into the grey zone of small, choppy junk. By the second week, from September 6th onward, we're back to tiny swells with onshore winds and lumpy conditions. The standout of the whole window is that September 5th afternoon. Even then, it's only a one out of ten kind of day. If you’re desperate for a paddle, that’s your best bet to get wet.
This is a classic blank run for the area. It doesn’t stay this poor forever, and forecasts can shift, but for now, keep the board in the bag.

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.
