The Lowdown
Alright folks, Rusty here. Let's have a look at what's coming down the pipe for Caspar Creek.
To be straight with you, the next week and a half is a bit of a rough patch. We’ve got swell coming in, but it’s almost constantly getting chopped up by a cross-onshore wind, and the forecast is calling it "poor surf conditions" straight through the 10th of August. The water is sitting at 58°, which is pretty much normal for the time of year, so no surprises there.
The first real glimmer of hope shows up on the afternoon of Thursday, the 13th of August. The wind finally drops off and goes glassy, and the swell hangs around 6 ft from the NW. That’s a solid, clean wave. The energy is moderate at 552, and we’re seeing a 9-second period, so it’ll have a decent shape. This is easily the standout of the whole forecast. It’s a consistent spot, Caspar Creek, so it should be breaking well, but it’s also "often" crowded, so expect company.
After that, the swell drops off hard. We get a little spike of long-period energy on the 19th of August (Wednesday), with a 4 ft swell from the WNW at a very long 13 seconds. That energy reading is 422, which is moderate, but the wind is light and offshore, which is a big positive. However, it’s marked as "marginal" due to questionable tide conditions, so it’s a gamble. The period is long enough that it might be a bit straight for this beach setup, but it’s worth a look if you’re chasing something clean.
For the rest of the run into the 22nd of August, it’s either tiny or choppy. The morning of the 22nd has a 4 ft swell from the NW, but it’s a short 5-second period and cross-onshore, so it’s not going to be any good. The afternoon gets a weird 2 ft swell from the SW with a 21-second period, but that’s a long, weak ripple that won’t do much here.
So, bottom line: if you want a wave, your best bet is Thursday afternoon, the 13th of August. That glassy session is the one to circle. The 19th of August is a promising but less certain call. The rest of the time, you might as well leave the board in the car.
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.

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.
