The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for Caspar Creek. I gotta be straight with you – this 16-day window is a tough one. We’re looking at a long, dry spell with very little to get excited about, and the first real chance of anything surfable doesn’t show up until the middle of next week.

The stretch from now through to the 18th of August is pretty much a write-off. We’ve got a pulse of swell kicking off Tuesday afternoon, the 11th, with a 7ft NW swell, but it’s a short-period 8 seconds and the wind is a cross-on. The water is sitting at 55°, which is a bit colder than usual for this time of year. The combined energy is moderate (715), but the conditions are marginal, and the scores are poor. Wednesday the 12th sees the swell bump up to 8ft, but the wind strengthens and it’s choppy. Thursday the 13th offers a bit of a drop in size, but the wind is still messy. From Friday the 14th all the way through to Monday the 17th, the swell just fades away into tiny, weak waves, barely registering. We’re talking combined energy dropping from 171 down to a paltry 22. It’s a proper flat spell, and honestly, for a spot like this, that’s not unusual when the forecasts go quiet.

Now, the first glimmer of hope comes on the morning of Wednesday the 19th of August. After days of nothing, we get a little 4ft SW swell and, get this, glassy conditions. The wind is light from the WSW, basically nothing. The combined energy is moderate (376). It’s surfable, but it’s ordinary. It’s the best we’ve got, but it’s not a standout. The rest of that week and into the next is a mix of cross-onshore winds and small, short-period swells that just don’t line up. We see a few pulses of longer-period SW groundswell around the 23rd and 25th, with periods of 18-19 seconds, but the swell heights are tiny (1ft to 3ft) and the wind is always cross or cross-on. That long-period energy would be fantastic for a point or reef, but at a sheltered spot like Caspar Creek, it just doesn’t have the size to push in.

The very end of the run, on the 26th of August, sees another spike of short-period NW swell, 7ft to 8ft, but the wind is cross-on. Combined energy is moderate to strong (803), but the conditions are poor. It’s big, but it’s messy.

So, what’s the call? There’s no real standout in this entire 16-day run. The only window that’s even worth a look is Wednesday morning, the 19th of August, for that brief glassy moment on a small, weak swell. Keep your expectations low, and remember, forecasts can change. For now, it’s a waiting game.

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.
