The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking for Caspar Creek over the next couple of weeks.

Alright, straight up, I gotta be honest with you – this is a grim stretch of days for Caspar Creek. The first solid option doesn’t show up for a while, and even then, it’s a struggle. The water temp is about average for this time of year, so nothing wild there.

The first chance to get wet comes on Wednesday, August 12th, with some knee-to-waist high swell pushing in at 7 ft from the NW. But the wind is a cross-onshore breeze from the WNW at 6 mph, leaving it a little bumpy. It’s a sheltered spot, so it’s holding some energy, but the combined energy is moderate at 634 and the period is a short 8 seconds. Honestly, it’s a marginal call. Things get worse that afternoon when the wind picks up to 12 mph and the chop sets in.

Thursday the 13th starts with a 7 ft NW swell and an offshore wind from the W at 6 mph. That sounds promising, but the period is still short at 8 seconds, and the combined energy is moderate (720). The wind is clean, but the wave comment says it’s marginal. It’s the best of a bad lot, but I wouldn’t call it a standout.

After that, it’s a straight downhill slide. Friday the 14th drops to 4 ft, and the wind goes onshore, making it poor. From Saturday the 15th through to the 17th, we’re looking at dropping swell – 3 ft, 2 ft, 2 ft – all with light onshore or cross-onshore breezes. The energy drops to weak (100 and lower). You’re basically looking at flat, choppy water.

We hit a real dead zone from the 18th through to the 22nd. Swell bottoms out at 1.0 ft to 3 ft, mostly with cross-onshore winds. The combined energy is weak, sitting between 25 and 435. There’s a weird spike on the 18th afternoon with a 1.0 ft swell and a 15-second period, but that’s just a long-period nothingburger. Not worth a paddle.

A bit of a pulse shows up on the 23rd and 24th, but it’s all cross-onshore wind messing it up. The 24th afternoon sees a jump to 7 ft from the NW, but with a short 7-second period and a moderate breeze from the NW at 9 mph, the combined energy is 552 – moderate, but the wind is ruining it. The wave comment calls it poor.

The best chance in the whole window might be on the 27th, which is Thursday morning. That’s a full 15 days out, so take it with a grain of salt. But it shows a 2 ft swell from the SW with a long 14-second period, and an offshore wind from the WSW at 6 mph. The combined energy is moderate at 460. It’s a long-period groundswell, so at a beach break like this, it’ll likely break a bit straight and fat, but with clean offshore wind, you might find a few fun ones. It’s the only time the wind really lines up right.

Bottom line: Caspar Creek is a write-off for nearly two weeks. The only real glimmer is that distant Thursday the 27th morning, with clean offshore wind and a long-period SW swell. It’s promising but far out. For now, leave the board in the shed.

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.
