The Lowdown
Alright folks, Rusty here. Let's check out what Caspar Creek is serving up over the next couple of weeks.
First up, the water temp is sitting at 59°, which is pretty usual for this time of year, so nothing to worry about.
The truth is, this forecast is a bit of a slow burner. We’ve got a long stretch of pretty average conditions coming up. From Sunday 6th September right through to the morning of Thursday 17th September, the surf is just not cooperating. The wind is nearly always a cross-onshore breeze, and the waves are either small or messy. Monday 8th Tuesday afternoon is the very first time we see a glimmer of hope – a glassy 4ft NW swell, but it’s small and the energy is moderate (236). It’s surfable, but nothing to write home about.
The real standout, the only time I’d say it’s truly worth paddling out, is on Friday 18th September afternoon. We’ve got a glassy surface with a light WSW breeze, and the swell is a clean 2ft from the SW. What’s really exciting is that long period – 19 seconds – that’s proper groundswell energy. The combined energy is a solid moderate (420) but it’s that long period that will make the waves punchy. Caspar Creek is a sheltered spot, so this long-period SW groundswell should wrap in nicely. It’s a beginner-friendly size, but it will be a bit inconsistent with those long waits between sets. Still, you’ll be stoked on it.
The following morning, Saturday 19th September, looks like it could be okay early with that 2ft SW swell and 18-second period, but the wind swings onshore, so it’ll be a short window.
Bottom line: The first 11 days are a write-off, mostly due to the wind. Don't even bother. Your best bet is that Friday 18th September afternoon. It’s not a big swell, but the quality and the glassy conditions will make it a special session.

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.
