The Lowdown
Alright folks, Rusty here. Let’s have a look at what Caspar Creek has in store for us over the next couple of weeks. Straight up, the gut feeling on this one is a bit of a bummer. For a spot that’s usually consistent, we’re looking at a real dry spell for most of the forecast period. Don’t get your hopes up for anything decent until we’re well into the second week.
The water is running a touch colder than usual for this time of year, about 57°F, which feels a bit more like early autumn than late summer.
So, for the first ten days, from August 24th right through to September 2nd, it’s pretty grim. We’ve got persistent onshore or cross-onshore winds from the NW almost every day, and the wave surfaces are just chopped up and messy. Even when the swell bumps up a bit around the 28th and 29th, with 4ft to 8ft of short-period, weak NW windswell (combined energy hitting 585), the wind just kills it. That afternoon on the 29th sees 8ft of swell but with a 7-second period and a moderate cross-onshore breeze – that’s not surfable, that’s a washing machine. There’s a solid gap of over a week with absolutely nothing worth paddling out for.
We finally get a glimmer of hope on Thursday, September 3rd. The swell starts to build, with some 8ft to 12ft NW swell rolling in, but it’s still a bit messy. The real standout, the one you want to circle on the calendar, is Friday, September 4th. The afternoon session is where it’s at. The swell is a solid 10ft from the NW with a 10-second period (combined energy 1583), but the magic is the wind. It’s going glassy. That’s a rare and beautiful thing at Caspar Creek. For the experienced crew, this is the moment. The waves will have real power and shape. Just keep in mind, with 10ft swell, this is strictly for the experts.
Following that, Saturday, September 5th, still looks pretty good. The morning starts clean with offshore wind and a 8ft NW swell (1245 combined energy), and the afternoon turns glassy again with a smaller but still fun 7ft swell. Sunday morning, September 6th, also has potential with offshore wind and 6ft of groundswell from the NW (508 combined energy), which is a bit more manageable for the confident intermediate.
After that brief window of quality, we slide back into choppier cross-onshore conditions for the last couple of days of the forecast, with the swell staying solid around the 7ft to 8ft mark. It’s not going to be as clean, but the energy (1298 combined energy on the 8th) is there for the die-hards.
So, bottom line: suffer through the first week-plus of chop. The only real standouts, the ones worth planning around, are the glassy Friday afternoon and the clean Saturday and Sunday mornings of September 4th, 5th, and 6th. Mark it.

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.
