The Lowdown
Alright folks, Rusty here. Let’s be honest right off the bat: this stretch looks pretty bleak for Caspar Creek. You’re looking at over two weeks of onshore wind and messy conditions. The water’s a bit colder than normal for this time of year, sitting at 56°, so you’ll want that extra rubber.
The whole run kicks off on Tuesday morning the 18th of August with a weak, short-period 4ft NW swell and the combined energy is a moderate 169. But with a cross-on breeze, it’s just wind-rippled junk. That sets the pattern. The swell bumps up a bit on Wednesday the 19th to 6ft, and the energy climbs to 573, but again, it’s cross-on and choppy. Thursday the 20th brings a cleaner looking 3ft WNW groundswell with a 12-second period – that’s got a decent pulse to it with 374 energy, but it’s still cross-on with a gentle breeze so it’ll be bumpy and messy.
Honestly, the only flicker of hope comes on Sunday the 23rd of August in the afternoon. Swell drops to 5ft from the NW, period at 9 seconds, and the wind goes super light – almost nothing at 3 mph. The combined energy sits at 501. It’s still technically cross-on, but with that little wind it’ll be small wind ripples, not total chop. The score ticks up to 'marginal' which is the best we’ll see. If I had to pick a time to paddle out, that’s it. But keep expectations low. It’s a sheltered beginner wave at Caspar Creek, and even then, it’s only barely worth a look.
Beyond that, we get a few isolated moments like Monday the 24th morning with an onshore wind and a 2ft SW swell with a long 18-second period (energy 424), and again Tuesday 25th afternoon with another 2ft SW 16-second swell that goes onshore. Both are rated marginal. But it’s thin, small, and inconsistent.
From the 26th of August into early September, the swell gets bigger – up to 8ft with energy hitting 957 – but the wind howls from the NW at 18 to 25 mph and it’s cross-on all the way, turning it into lumpy, blown-out mess. That’s kite-surf territory, not paddle.
Bottom line: there are no good surf options in the 16-day window. The only real highlight is that very light wind window on Sunday afternoon the 23rd of August. For the rest, it’s choppy, weak, or just plain ugly. That’s the way it goes here sometimes. Forecasts can change, but for now, maybe clean the wax off your backup board and wait.
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.
