The Lowdown

Alright folks, Rusty here. Let's take a long look at what Caspar Creek has in store for us over the next couple of weeks.

Gotta be straight with you – the first week and a half is a real write-off. From Sunday the 16th right through to Friday the 21st, it's all "poor surf conditions" with nothing but cross-onshore wind messing up the lines. Swell is mostly short-period, weak stuff from the NW, never really getting its act together. The water's sitting at a cooler 55°, which is a bit colder than normal for this time of year. It's just a grind.

We finally get a glimmer on Sunday the 23rd of August. The morning is still a bit iffy with some questionable conditions, but the afternoon shows some real promise. That's where we see our first standout. The wind drops right out and goes glassy – dead calm. A new long-period groundswell from the SW (19 seconds) kicks in, pushing combined energy to a solid 547. Swell height is around 6 ft, which is a solid size but manageable. That glassy wind is the real treat; it'll be as clean as it gets.

The next day, Monday the 24th, holds some potential too. The morning is messy again, but the afternoon turns glassy with a 2 ft, 18-second SW groundswell. It's smaller, but with the calm conditions, a log or a single-fin would be the call.

After that, it's back to a whole lot of nothing. From Tuesday the 25th all the way through to the start of September, it's more of the same poor, choppy, cross-onshore junk. A few moments here and there look marginal, but nothing you'd bother paddling out for. The second week is a total dud, with only the faintest whispers of energy that never seem to line up with favorable wind.

So, mark your calendar for the afternoon of Sunday, August 23rd. That glass-off with the long-period SW groundswell is our best bet. Get there before the crowds catch on.

Rusty.

Information about the Caspar Creek Surf forecast

The above surf forecast table for Caspar Creek provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Caspar Creek can be found by selecting the local surf guide option on the grey menu. Our Caspar Creek 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 (Caspar Creek) 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 Caspar Creek 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.
