The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up at Caspar Creek.

Alright, straight up, we’re looking at a pretty bleak start. There’s a solid week of poor conditions ahead, so don’t get your hopes up for any decent waves just yet. The first bit of real hope doesn't show until Thursday, September 10th.

That Thursday morning is your first chance. The wind goes glassy, and there’s a long period groundswell rolling in from the SW at 17 seconds, pushing a clean 3ft wave. The combined energy is moderate (484). It’s small and clean, but it’s the first light at the end of a long tunnel.

Now, for the standout. Friday, September 11th, the swell really fires up. We’re looking at a chunky 10ft SW groundswell with a 12-second period, and the combined energy is a massive 3002. That is proper, powerful, and big. This is for experienced surfers only – well over that 8ft mark. The morning wind is a light cross-shore, so it won’t be perfect, but the power is undeniable. This is the one to circle on the calendar, but keep in mind it’s still a long way out, so stay tuned.

After that, conditions get messy again with cross-onshore winds and poor surf quality through the following week. There’s a little glimmer on the last day, Thursday, September 17th afternoon and Friday, September 18th. The 18th afternoon looks special with calm, glassy wind and a very long 19-second SW groundswell pushing 3ft. The energy is strong at 1206, and the call is for “very good surf conditions.” That’s another one to keep an eye on, but again, it’s deep in the forecast.

So, in short: suffer through the first week, hit that Thursday morning the 10th for a tiny glassy session, and keep a close watch on the big Friday the 11th and that very promising Friday the 18th afternoon.

Stay tuned, 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.
