The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for Caspar Creek. I gotta be straight with you – the next 16 days are a mixed bag, and we’re gonna have to pick our moments carefully. There’s no real standout, world-class window here, just a few brief windows where the conditions might line up for a session.

The forecast kicks off on Saturday, 5th September, but it’s not looking good. We’ve got 4.3ft of NW swell coming through with a 9-second period, but the wind is cross-on, making it choppy and messy. The combined swell energy is moderate at 294, but the quality is poor. This pattern sticks around through Sunday and Monday, with the wind staying cross-on and the surf mostly small and bumpy. Monday morning is a slight tease with a 4.3ft NW swell and light wind, but it’s still cross-on, so the waves will be lumpy. Not worth paddling out for.

Tuesday, 8th September, is where we get our first real glimmer of hope. The morning is cloudy with a 4.3ft NW swell and a 7-second period, but the wind swings to onshore, and conditions are still poor. However, the afternoon brings a little bit of magic. We get some clouds, a 3.9ft NW swell, and the wind drops to glassy. The combined energy is moderate (156), and the wave comment says “surfable waves but very ordinary conditions” with a score that suggests it’s not too bad. This is the first real chance to get a clean wave, but it’s going to be small and weak. It’s the best of a bad bunch so far.

Then we skip ahead to Wednesday, 9th September. The swell drops right off to 1.6ft in the morning, but the period jumps to 16 seconds – that’s a very long-period groundswell from the SW. The combined energy jumps to 257, but the wave size is tiny. The afternoon sees a similar 2.6ft SW swell with a 19-second period and a big energy reading of 521. This is a classic case of a long-period swell that’s going to break too straight for a beach break like Caspar Creek. It’s better suited to a point or reef, but we don’t have one here. The conditions are marginal at best, with a light cross-on wind. I wouldn’t get too excited.

Thursday, 10th September, continues the same theme. A 3.0ft to 3.3ft SW swell with a 17-second period and strong energy (590-684). The wind is light from the WNW, but it’s cross-on in the afternoon. Again, these are marginal conditions. The long period might make the sets look good, but the wave faces will be fat and hard to ride.

The next real chance comes on Saturday, 12th September. The morning has a 3.0ft SW swell with a 14-second period and strong energy (513), but the wind is cross-on. The afternoon, however, turns glassy again. We get a 3.3ft NW swell with a 9-second period and moderate energy (202). The wave comment is “surfable waves but very ordinary conditions.” This is another small window of clean, glassy surf, but it’s not going to be powerful.

Sunday, 13th September, offers a similar story: a glassy afternoon with a tiny 2.6ft NW swell and a 9-second period. The combined energy is weak (112), but it will be clean. It’s a micro-session for the longboard or a foiler.

The forecast gets messy again after that. From Monday, 14th September, through Wednesday, 16th September, the swell drops to under 2.0ft, and the wind is either onshore or cross-on and often strong. The combined energy is low. This is a flat spell.

Then, things get interesting, but not in a good way. On Thursday, 17th September, a big NW swell arrives. The morning sees 4.3ft at 12 seconds with a massive combined energy of 801, but the wind is a fresh cross-on 30 km/h, making it lumpy. The afternoon is a beast: 9.8ft at 12 seconds from the NW, with a very strong energy reading of 2619. The wind is a strong breeze at 45 km/h, cross-on, and the waves are described as “strong cross-onshore and messy.” This is huge, powerful, and dangerous – only for the bravest experts, and even then, the wind will ruin it. Friday, 18th September, is similar: 9.8ft to 11.5ft NW swell, very strong energy (2482 to 2180), but the wind is moderate to strong cross-on, making it choppy and messy. Saturday, 19th September, the swell drops

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.
