The Lowdown
Alright, Rusty here. Let's be straight with you – the next couple of weeks at Whipsiderry are a tough watch. We’re looking at a long, dry spell of poor surf conditions that runs from this Saturday, August 15th, right through until the end of the month. There’s really nothing surfable until we get towards the very tail end of the 16-day window.
The core issue is the wind. For days on end, we’ve got a steady diet of moderate to fresh cross-onshore breezes straight out of the north and northwest. That combo shreds any chance of a clean face. The swell is hanging around, but small, with a weak combined energy (mostly under 120). The water temp is sitting at 66°F, which is a good 4°F warmer than normal for this time of year – so the water feels lovely, but you wouldn't know it from the surface conditions.
The first glimmer of anything worthwhile comes way off on the morning of Saturday, August 29th. We finally see a shift to light offshore winds from the southeast. The swell is still tiny, just 2ft from the west with an 8-second period, and the energy is weak (58). But the forecast says "surfable waves but very ordinary conditions," which is the first time it's not a total write-off. That’s your best bet, but honestly, it’s a paddlers' paradise more than a surf spot for that one.
There is a minor clean-up on Sunday, August 30th, with a cross-offshore breeze, but the swell is even smaller at 2-2ft. If you’re desperate for a paddle and a few ankle-biters, that’s your other window. Everything before that is a flat, choppy mess. If these winds and small swell patterns hold, it might get more interesting for a kite than a surfboard.
So, in short: hunker down. It’s a long, poor run. The very end of the month holds the *only* door ajar, and it’s barely open.
Stay patient,
Rusty

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 Whipsiderry 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.
