The Lowdown

Alright folks, Rusty here. Let’s look at what’s shaping up for Caspar Creek. I gotta be straight with you – this stretch is looking pretty bleak for a while. The first week and a half is mostly a write-off for decent waves. We’ve got a long gap with no real recommendations, and the surf that does show up is messy or just not worth paddling out for.

The water is sitting at 55°F right now, which is a solid 4°F colder than usual for this time of year. That’s a noticeable chill, so a good 5/4mm wetsuit is your friend if you’re keen.

The first few days are a no-go. Tuesday morning (September 1st) is small, maybe 2ft from the NW, but with a light cross-shore wind and poor conditions. The energy is weak (109). It just looks bumpy and uninviting. That theme carries on through Wednesday and Thursday. We get a bit more size – 6ft on Thursday morning – but the wind is still cross or cross-on, and the forecast says marginal at best. The combined energy does climb a bit (528), but it’s not clean.

Friday morning (September 4th) is the first real teaser. We get a 7ft NW swell with a clean offshore wind – WNW at 6 mph. The energy is strong (1053). The problem is the forecast still calls it marginal, and it’s a bit meaty for most. If you’re an expert, that morning window might have a few, but it’s not the standout we’re waiting for.

After that, we slide back into a long run of poor surf. The wind switches to cross-on or onshore, the swell drops, and the energy fades. Nothing is worth a second look until the second week.

Then, on Thursday, September 10th, we finally get a proper window. The afternoon looks glassy – WSW wind at just 3 mph – with a 4ft NW groundswell running on a 12-second period. The energy is strong (900). The forecast says “good surf conditions.” This is a rare moment where the stars align. The waves will be clean, with some shape from that longer period. It’s not huge, but for a spot that’s been blown out, this is our best bet. The next day, Friday afternoon (September 11th), is another glassy session with 6ft NW swell, though the period drops to 8 seconds. Still, with glassy conditions, it’ll be fun. Just be aware that this spot is consistent, but crowds are often here, so expect company.

The following Monday (September 14th) has some promise, with a long-period 4ft NW swell (13 seconds) and light offshore wind in the morning, but the energy is huge (816) and the forecast is still marginal. Could be a sneaky one if the tide works.

So, the standout days are the afternoon of September 10th and the afternoon of September 11th – glassy, clean, and with some swell. That’s where you want to be. Everything else is a gamble or a straight-up miss. Keep an eye on the long-range for the 14th, but it’s less certain.

Rusty, signing off.

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.
