The Lowdown

Alright folks, Rusty here. Let's get into it for Caspar Creek. We've got a slow start and a tricky 16 days ahead. No good waves to kick things off, with the first real glimmer of hope coming mid-week and then a whole lot of wind and cross-slop making things messy throughout the second week.

The whole pattern starts quiet. Wednesday the 2nd and into the first half of Thursday the 3rd is a mixed bag of cross-shore wind and poor surf. The wave energy is weak to moderate (397 down to 315 and then later 1069), but the conditions just aren't playing ball. The real standout arrives on Thursday afternoon, the 3rd of September. That’s where we get our best opportunity. Swell is coming from the WNW at 6ft, with a 10-second period and glassy wind conditions. That's clean, that's rideable, and the energy is solid (826). For Caspar Creek at this time of year, that's as good as the forecast gets.

But it's a one-trick pony. Friday the 4th is all cross-onshore wind and a dropping swell, with the wave state turning choppy and messy. Saturday the 5th through Tuesday the 8th is a long run of poor surf conditions, with winds onshore or cross-onshore and the swell energy dropping away. The combined energy readings drop into the low 200s and 250s, which is weak. Wednesday the 9th into Thursday the 10th sees the energy go flat, down to a mere 56 on Thursday morning. That’s a real lull.

The second week, from Friday the 11th of September onward, is basically a write-off for quality surf. There’s a little lump around the 11th and 12th, but it’s all cross-onshore wind, with a moderate breeze kicking up a chop. The swell is mostly long-period groundswell from the SW hitting 17 seconds on the 10th afternoon and 15 seconds on the 11th, but that long period will make the beach break sectiony and hard to link up. The wave energy does climb at times (622, 716, 606), but the conditions are just too rough.

And then the end of the run from the 13th through the 17th is actually quite big, but completely unsurfable. We get swell heights of 8ft with a combined energy of over 1600 (1602 to 1684) but the wind is a stiff cross-onshore breeze. That size and wind will create dangerous, blown-out conditions. That's more of a kite-surfing situation than a paddle-surfing one, especially for a beach break.

So, bottom line: Thursday afternoon the 3rd of September is your one and only standout session. Get it while it's glassy, because after that it's a long stretch of onshore wind and messy waves.

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.
