The Lowdown
Alright folks, Rusty here. Let's get into it.
Right off the bat, I gotta be honest with ya – this 16-day window for Caspar Creek is a tough one to swallow. We're looking at a long stretch of poor conditions, with that pesky cross-onshore wind messing things up day after day. The water temp is sitting around 56.8°, which is a touch cooler than average for this time of year.
The first real glimmer of hope doesn't pop up until Wednesday, September 2nd. The morning is still a bit sketchy with marginal surf, but into the afternoon, things finally come together. The wind goes glassy, and we’ve got a solid 5.9ft groundswell. The wave energy is strong, clocking in at (700), and with those light conditions, it’s gonna be clean. This is the standout of the whole forecast.
Thursday, September 3rd, follows up with more promise. The afternoon session looks epic with glassy conditions again, and the swell bumps up a bit to 7.2ft from the NW. That's getting into the "too big for beginners" territory, but for anyone with some experience, it's going to be firing. Wave energy is even stronger at (833). Just keep an eye on the morning, which might have a light offshore breeze but the report says it's a little marginal.
Overall, the first couple weeks are a write-off with that persistent cross-onshore wind. But if you can hold out, the very end of the forecast has a couple of days that look like they could be worth the wait. The rest of the period after that slides back into poor surf. This is a classic case of patience paying off.
Stay stoked.

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.
