The Lowdown
Alright folks, Rusty here. Let’s get real about Caspar Creek. It’s a tricky one—this stretch is a sheltered spot, pulling in from the NW, and what we’ve got on the table is a long 16-day window that’s looking pretty grim. There’s a big gap here with no surf worth chasing because the conditions are just plain poor. For the first week and a half, it’s basically a write-off thanks to persistent cross-onshore winds and choppy, lumpy surf. The water temp is sitting at 57°, which is about 1° cooler than average for this time of year, so it’s nothing unusual, just a little nippy.
The first sniff of anything close to surfable doesn’t arrive until Wednesday afternoon, September 2nd. That’s a long way off—over a week from now. The swell is small, only 2ft from the SW, but the period is a long 16 seconds, which is proper groundswell. The wind goes glassy, and that’s a major positive. It’ll be clean, but the wave energy is weak (326) and the wave comment says “surfable waves but very ordinary conditions.” It’s not a standout, just the only window where you might get a few clean little lines.
For the rest of the period, it’s a no-go. Even when the swell bumps up to 6ft on Sunday the 23rd or 8ft on Sunday the 30th, the wind is always cross-onshore or onshore, and the quality is poor. The swell energy does get strong—like 904 on the 30th—but with that 28 mph NW wind, it’s a messy, choppy, lumpy mess. That kind of setup is more interesting for kite surfing than paddle surfing.
Honestly, there’s no standout session here. The only bright spot is that tiny glassy window on the 2nd of September. If you’re desperate for a paddle, that’s your best bet, but keep expectations low. It’s a long dry spell, but that’s the way it goes sometimes at a sheltered spot like this.
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.
