The Lowdown
Alright folks, Rusty here. Let me level with you. The next 16 days at Caspar Creek are mostly a story of wind-ruined waves and waiting. There's a shimmer of hope right at the very end, but for the bulk of the forecast, we're looking at a lot of no-go. We're talking about a solid 13-day stretch of poor conditions from September 7th all the way through the 19th. The wind is just relentless, blowing cross-onshore from the NW almost every day, and that's just trashing the surface.
The first hint of something better doesn't roll in until the morning of Sunday, September 20th. That morning, the wind finally drops and we get a glassy session. The swell is a small 3ft from the SW, but with a period of 19 seconds, that's a proper long-period groundswell. The energy is solid (659), but at this size, it's going to be clean and workable. The real standout, the one you've been waiting for, is the afternoon of Tuesday, September 22nd. That's the best on offer. The wind goes glassy again, and we see a solid 8ft swell from the WNW, with a period of 13 seconds. The combined energy is massive at 2322, and the conditions are forecast as excellent for experienced surfers. This is a real, proper swell with clean conditions. For the record, the water temp is about 60° at the start of the period, which is pretty normal for this time of year.
So, the plan is simple. Be patient. The first week and a half is a write-off. The 20th might offer a little glassy sneak peek, but Tuesday the 22nd is the date to circle on the calendar. A big, clean, glassy swell for the experienced crew. The rest is just a waiting game. Enjoy the time off, I guess.

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.
