The Lowdown
Alright folks, Rusty here. Let's break down what Caspar Creek has for us.
I'm not going to sugarcoat it. This is a tough run. For the better part of a week and a half, the surf is a no-go. The wind is almost always cross or cross-on, and the swell is just ugly. The first thing that even looks borderline doesn't show up until the 20th of September, and it's still not great.
The real payoff is way out at the end. On Tuesday the 22nd of September, things finally line up. We get a solid 8ft groundswell from the NW with an 11-second period. The wave energy is very strong (1880). But the big news is the glassy conditions on Tuesday afternoon when the wind goes totally calm from the south. That's your best bet. Then on Wednesday the 23rd, we get another glassy afternoon with 7ft of NW swell (1227 energy) and flat calm. That's your window.
Keep in mind, that 8ft surf is for experts only. Beginners, stay on the sand. And for the first ten days, honestly, with all that choppy cross-shore wind, it looks more like a kiteboarder's paradise than a surfer's.
The water temp is sitting right around average for the time of year at 59°. So you're waiting, and waiting, for that final weekend. It's a long stretch, but those glassy days at the end might be worth the wait.
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.
