The Lowdown
Alright, Rusty here, lookin’ at the 16-day run for Caspar Creek.
Gotta be honest, it’s mostly a bummer. Wind’s swingin’ cross-on almost the whole way, and the wave quality is called “poor” for nearly every session. Water temp’s 56°F, a bit colder than usual for this time of year—need a thick suit.
Swell comes mostly from the NW, from 2ft up to a solid 10ft on August 27th, but that day’s blown out by a fresh cross-onshore wind and lumpy conditions. Combined energy hits 1186 (very strong), but it’s messy.
The one bright spot? Monday afternoon, August 24th. The wind goes glassy—dead flat calm—on a 2ft SW groundswell with a super long 18-second period. That’s a groundswell that favors a sheltered nook like Caspar Creek. Combined energy’s moderate at 369. It’s the only window where conditions aren’t rated poor, and the surf is clean and rideable. Crowds are often there, but for that glassy window, it might be worth joinin’ the pack.
After that, it’s back into a long run of choppy, lumpy, cross-on conditions. If you’re into kiting, those windy, lumpy 6-10ft days might be fun, but for paddle surfing, this forecast is a dud. One good afternoon is all we’ve got.

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.
