The Lowdown
Alright folks, Rusty here. Let's have a look at what Caspar Creek has got cooking for us over the next couple of weeks.
Right off the bat, I gotta be straight with you: this stretch of coast is in for a long, frustrating spell. For the first week and a half, from Friday the 11th right through to Wednesday the 23rd of September, the surf is pretty much a write-off. The wind is a constant issue, mostly cross-onshore from the northwest, and that's just chopping everything up into a messy, lumpy soup. We're seeing swell heights around 3ft to 10ft, but it doesn't matter because the quality is just poor. Even when the swell bumps up to 10ft on Monday the 14th, the conditions are so onshore and lumpy it's more of a washing machine than a wave. The combined swell energy gets up there – 813 to 1436 (moderate to strong wave energy) – but it's completely wasted with the wind.
Now, there is a little light at the end of the tunnel, but it's a long way off. Things finally start to look up on Thursday the 24th of September. Thursday afternoon, we get a moment of glassy conditions and a clean 7ft swell from the northwest. The wind goes light and variable, and the wave comment says "expect good surf conditions." That's the first real window in nearly two weeks. The combined swell energy is 832 (moderate wave energy), which is solid.
Then, hold onto your board, because Saturday the 26th of September afternoon is the standout. We've got a very long period 16-second groundswell from the west-northwest, stacking up to 6ft. The wind goes glassy, the sky is partly cloudy, and the wave comment says "expect very good surf conditions." The combined energy is pumping at 1370 (strong wave energy). A long-period swell like that at a sheltered spot like Caspar Creek, which is best with swell from the northwest, could produce some really clean, lined-up waves. Keep in mind, with that period and direction, it might offer better shape at a point or reef, but if it lines up here, it could be special.
As for the water, Caspar Creek is sitting at 58°F right now, which is a touch cooler than average for the time of year, but nothing wild.
So, to sum it up: this is a tale of two weeks. The first week and a half is a total bust with constant cross-onshore winds. Don't even bother. The last two days of the window, with Thursday afternoon and especially Saturday the 26th afternoon offering glassy conditions and some real energy, are the only true standouts. Mark those dates in your calendar, but be patient – a lot can change in two weeks.
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.
