The Lowdown
Alright, let’s talk Caspar Creek. To be straight with you, the next two weeks look pretty grim. There’s day after day of poor surf – the wind’s almost always cross-onshore, and the swell is messy. The combined energy is mostly on the weak side early, like 180 and 188, then it bumps up to 271 and 604, but none of it is clean.
From Friday the 28th of August through early September, it’s a grind. Swell runs from 1.3m to 2.4m out of the NW, but the period is short – 6 to 8 seconds – so it’s gonna be lumpy and choppy. Winds are moderate to fresh, making it worse. Not worth the drive.
There’s one real bright spot: Thursday morning, the 3rd of September. The wind goes glassy – totally calm – from the west. Swell comes in at 1.6m from the NW with an 11-second period, giving it some real shape. The energy hits 589, which is moderate, and for this sheltered spot, that’s actually decent. It’s the only time all forecast that’s labelled “good surf conditions.” Caspar Creek is a consistent beginner break, so that 1.6m might be a bit much for the rookies, but for anyone else, that glassy morning could be magic. Water temp’s 57°F, pretty normal for the season.
After that it’s back to the same old story: cross-onshore wind, poor surf, and a lot of days to skip. There’s a couple of long-period SW swells on the 2nd and 10th of September (17 seconds), but the wind ruins them. This kind of quiet stretch is pretty normal here when the wind doesn’t cooperate. So mark that Thursday morning on your calendar – it’s the only real standout.

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.
