The Lowdown
Alright folks, Rusty here. Let's have a look at the run of surf coming up for Caspar Creek.
Right off the bat, I gotta be straight with you – the first week-plus is a tough watch. The forecast is calling for a long stretch of poor surf conditions straight through until the morning of Tuesday the 15th. The wind is stuck in a cross-on pattern, mostly from the NW, and it's messing up what little swell there is. The water temp is about 59°, which is normal for this time of year, but that's about the only thing that's average.
The first real glimmer of hope comes on the afternoon of Tuesday the 15th. The swell stays a bit chunky, but it's still a bit of a mess. You'll be looking for a window in the morning, but the afternoon is still not great. The combined energy is moderate (770), but it’s not clean enough to get excited about.
Honestly, the best bet in this whole 16-day window is a long way out. Mark your calendars for Tuesday the 22nd of September. That afternoon, we finally get a break in the weather. The wind goes dead calm, glassy as a mirror, and there's a solid 8ft NW swell rolling in. The combined energy is strong (1312), and the period is a decent 10 seconds. That’s the standout session. It’s a fair way off, so don't put all your eggs in that basket, but it’s the only time the forecast lines up for something truly special. The morning of the 22nd is also okay, but the wind is a little cross-on, so that afternoon is the pick.
The 21st of September also has some potential with a 10ft NW swell, but the wind is a bit off, making it a marginal call. That’s a big wave for the average punter, so experts only for that one.
So, hang in there. The first week is a write-off, but there’s a glassy beauty waiting for us on the 22nd if the forecast holds.
Rusty, signing off.

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.
