The Lowdown
Alright folks, Rusty here. We’re looking at a stretch that’s going to test your patience. The only spot with any real consistency on the calendar is Caspar Creek, but even then, the conditions are a tough watch.
For the first week, from Friday the 21st of August right through to the end of the month, it’s mostly a write-off. The wind is stubbornly cross-on from the NW, and while the swell shows up, it’s raw and messy. The water is sitting at 57°, which is about normal for this time of year, nothing wild there. The combined energy on the 23rd (Sunday) hits 508 (moderate), but it’s a short-period 5ft to 7ft NW windswell under a cross-onshore breeze – that’s just choppy, lumpy, and not worth paddling out for. The rest of that week is similar, with energy readings mostly in the 200–500 range, but the quality is poor.
There’s a slight flicker of hope on the 3rd of September (Thursday), when the wind swings light westerly, going almost onshore. The swell is 5ft from the NW with a period of 8 seconds, and the combined energy is 364 (moderate). It’s a marginal call, but it’s the closest to rideable we get. The afternoon of the 3rd sees a 5ft NW swell with a 1/10 rating, which is a glimmer. But then the wind builds again.
The real stand-out in the whole 16-day window is the morning of the 5th of September (Saturday). The swell jumps to 8ft from the NW, period 9 seconds, and the combined energy roars up to 939 (strong). That’s a powerful push. But here’s the catch – the wind is a fresh cross-on from the NW at 15 mph, chopping it up. For a sheltered, beginner-friendly break like Caspar Creek, that’s just not going to be clean. It’s more of a kite-surfing setup than a paddle-surfing one. The afternoon of the 5th goes even bigger at 10ft (energy 1366 – very strong), but with 22 mph NNW cross-on wind, that’s expert-only, heavy, and messy.
Truth is, there’s no true standout session here. The best bet is the 3rd of September, if you’re desperate for a wave, but it’s still marginal. The rest of the time, the NW wind just won’t let up. It’s a tough run.
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.
