The Lowdown
Alright folks, Rusty here. Let's have a look at what Caspar Creek has in store for us. It's a sheltered spot that works best on a NW swell, but honestly, the next couple of weeks are looking pretty grim for a paddle.
Right now, and for the rest of this week, it's a write-off. We've got a moderate cross-onshore breeze that's just trashing the surface. The swell is there, hanging around 8ft to 8ft with a short, weak 8-second period, but with that wind, it's just a choppy, messy line-up. The wave energy is moderate at best (804), and the water is sitting at 58°, which is about average for this time of year. It’s not surfable.
This poor run looks set to continue day after day. We get a little glimmer of hope on Friday the 14th, with the wind going glassy in the afternoon. The swell drops to 4ft, but it’s still a short 8-second period and the wave energy is weak (227). The report says "surfable waves but very ordinary conditions," which is about the best we can say for it. That's not a standout, just a slight reprieve. Then it’s back to flat and weak through the following week.
The second week doesn't offer much hope for a proper surf either. There's a notable spike on Sunday the 23rd of August, with the swell jumping to 10ft and the wave energy getting very strong (1286), but it’s still a cross-onshore wind with a short 8-second period. That’s just a big, blown-out mess for experts only. The following Monday the 24th has a similar story with 10ft of NW swell and glassy wind in the afternoon, but it’s all cross-onshore again, which will keep it from being clean.
Honestly, for the entire 16-day window, there's nothing that even comes close to being a good surf day. The wind is almost always from the NW, which is cross-onshore for this break, and the swell quality is consistently poor. The spot is consistent, but the conditions aren't cooperating. This is a classic case where you'd be better off chasing a different coast or picking up another hobby for a while.
Rusty, signing off.

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.
