The Lowdown
Alright, Rusty here. Let's get straight into it. Gotta be honest with you – this is a tough stretch for Caspar Creek. We're looking at a pretty barren run for the next week and a half, maybe longer.
The pattern is all cross-onshore wind, which is a killer. The swell is coming in from the SW and NW, but the wind is just tearing it up. The water temp is about average for this time of year, nothing crazy there.
The first real chance of anything decent doesn't show up until Friday, September 4th, in the morning. Even then, it's a 1* call for a 6 ft NW swell with light wind. It's a marginal call, but it's the first blip on the radar after a long wait. The combined energy is moderate (680), but the wind is from the WSW, which is a light cross-onshore breeze. It's not ideal, but it's the best we've seen in a while.
Then there's a bit of a gap. But hold on... Sunday, September 6th, in the afternoon, things get interesting. The wind drops to glassy, with a 3 ft NW swell. The period is a nice 10 seconds, and the energy is moderate (292). The report says "glassy." That's the magic word. It's not big, but it'll be clean and fun for the longboard or a fish. This is the standout for the whole outlook.
And then... Tuesday, September 8th, in the afternoon. This is the one to circle. The swell jumps to 8 ft from the NW, with glassy conditions. The combined energy is strong (591). The report says "expect good surf conditions" with a 2* rating. That's the biggest, cleanest, most powerful swell of the whole 16 days. But with that 8 ft height, it's going to be a big, powerful wave. This is for experienced surfers only. The period is a short 7 seconds, so it will be a bit fat and won't have the long, drawn-out lines of a groundswell, but glassy wind on a 8 ft NW swell is a rare treat.
The rest of the time is just a write-off with the cross-onshore wind. A lot of waiting for a couple of windows. The glassy Sunday afternoon and the big Tuesday afternoon are the only real shows in town.
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.
