The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this 16-day window for Caspar Creek is a real tough one. We’re looking at a long stretch of nothing special, with a whole lot of choppy, onshore wind messing things up. The first few days are a write-off, so don't even bother waxing up until we get into the second week.
From Friday the 28th through to Monday the 1st of September, it’s all cross-onshore wind and pretty average conditions. Some waves are there, sure, but the quality is just not there. The water temp is sitting at about 57°, which is pretty normal for this time of year, so no drama there.
Now, the first real glimmer of hope, and the only standout I can point to, is the morning of Wednesday the 2nd of September. The wind goes glassy, and we get a long-period groundswell from the SW at 17 seconds. That’s a proper ocean swell. The wave height is only 2ft, but with that period and glassy conditions, it’ll be clean and lined up. The combined energy hits 378, which is a solid moderate energy. This is a sleeper day for a log or a fun mid-length, but it’s a one-off.
After that, Wednesday afternoon and into Thursday the 3rd it’s back to cross-onshore slop, with the swell building to 7ft by Thursday afternoon. That's expert territory and the wind is going to chop it up. The energy is strong, hitting 1172, but it’s a mess.
The morning of Friday the 4th of September is another marginal look. We’ve got 7ft of NW swell at 11 seconds with light onshore wind. The energy is huge at 1162, but the wind direction is not your friend. It’s a raw, powerful, and probably lumpy day.
Beyond that, from the 5th through the 12th, it’s a real mixed bag of cross-on winds and fading swell. Nothing really jumps out as worth the paddle. The 12th of September sees a weak, short-period swell from the SW, but it’s still cross-on.
So, to sum it up: the only real window for a clean wave is that Wednesday morning, the 2nd of September. If you can't make that, the entire 16-day forecast is a bit of a bust. The setup is mostly just choppy and cross-on, so it’s more of a kite day than a surf day through most of it. We’ll see if the forecasts tighten up, but for now, that’s the hard truth.
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.
