The Lowdown

Alright, folks, Rusty here. Let’s have a look at what Caspar Creek has in store for us over the next couple of weeks. I’ll be straight with you – it’s a bit of a frustrating outlook for this sheltered spot, with a whole lot of "almost there" but not quite.

The overall pattern is a long, drawn-out wait for clean conditions. For the first ten days, we’re dealing with a constant onshore or cross-onshore breeze that’s just messing up the surface. The water temp is sitting at 57°F, which is a full 2°F colder than normal for this time of year – you’ll feel that nip for sure.

We kick off on Saturday the 5th with a 4 ft NW swell, but that 9 mph cross-onshore wind has it all chopped out and messy. The wave energy is weak (266). Sunday the 6th is even worse, with the swell dropping to 3 ft and the wind picking up to 16 mph by the afternoon – just a total write-off.

There’s a tiny glimmer on Tuesday the 8th afternoon. The wind goes glassy, dead calm, with a 4 ft NW swell at 8 seconds. The wave energy is moderate (160). It’s surfable, but it’s very ordinary, nothing to write home about. That’s the best we get for the first week, and it’s a 1 out of 10.

Thursday the 10th sees a big jump in energy with a 17-second, 3 ft SW groundswell pushing the combined energy to 685, but that 9 mph cross-onshore wind ruins the party. It stays poor. This pattern of “swell but wind” just keeps going.

Now, look ahead to Saturday the 19th of September. That’s the standout. We finally get a proper pulse of energy. Saturday morning shows an 8 ft NW swell with an offshore wind (WSW at 3 mph) and the combined energy is a massive 2288 – that’s strong, powerful stuff. But it’s still listed as marginal for some reason. Then, Saturday afternoon is the real gem: 10 ft of NW swell, glassy conditions, and very good surf conditions predicted. The wave energy is still very strong (1508). That is the one to circle on your calendar, but it’s big – over 8 ft – so this is strictly for experts only. Beginners, stay on the beach that day. It’s nearly two weeks out, so treat it as a promising long-range call, not a guarantee.

Sunday the 20th drops off quickly, back to a 3 ft SW groundswell with a very long 19-second period, but the energy is moderate (664) and it’s just marginal.

So, the honest truth? There’s a whole lot of nothing for the first 10 days. Lots of days with no recommendation at all. The only true standout is that Saturday the 19th afternoon, with the glassy 10 ft NW swell. Get on it if you’re experienced, but don’t hold your breath for the rest of the window. Caspar Creek is a consistent break, but the winds are fighting us this time.

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.
