The Lowdown

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

Right off the bat, I’m not gonna sugarcoat it: the first week is a real struggle. We’re looking at a long, dry spell of poor-quality surf with onshore wind and chop. The wind is mostly cross-onshore from the NW, and the swell is short-period and weak. The first few days are a write-off for anyone wanting a proper wave. There’s a gap of about six days here where you’d be better off cleaning the wax off your board than paddling out.

The first real glimmer of hope comes on Tuesday the 8th in the morning. It’s not a classic, but the wind goes glassy, and the swell is a clean 4 ft from the NW with a period of 8 seconds. The combined energy is moderate (160). It’s surfable, but the conditions are still very ordinary. That’s the best of a bad bunch early on.

Then look at Wednesday the 9th afternoon. The swell direction shifts to the SW, and the period jumps to 19 seconds, giving us a long-period groundswell. The energy is strong (546). The problem is the wind is still light and cross-onshore, so the waves will be a bit bumpy, but this is a sign of better things to come. The wave height is only 3 ft, but that long period will make it look bigger than it is.

The real standout, the one you’ve been waiting for, is Tuesday the 15th in the morning. This is the pick of the whole forecast. The wind goes glassy, dead calm. The swell is a solid 6 ft from the NW, with a period of 7 seconds. The combined energy is moderate (502). The conditions are described as “expect good surf conditions,” and that’s exactly what we’re after. This is a proper session. The water temperature is 59°, which is about average for the time of year, so a decent 3/2 wetsuit is the call.

After that, the swell gets bigger, but the wind turns back to cross-onshore. By Wednesday the 16th afternoon, the swell hits 12 ft from the NW, with very strong energy (1754). That’s big, solid, expert-only territory. The wind is light cross-onshore, so it won’t be completely clean, but for the experienced crew, that’s a big, powerful swell. The period is short at 8 seconds, so it’ll be a bit dumpy and fast, but the power is there.

The following week continues with big, powerful NW swells, but the wind stays cross-onshore. The Thursday the 17th morning has a 8 ft swell with a period of 9 seconds and very strong energy (1926), and the wind is offshore from the WNW at 3 mph. That’s a good window. The swell is big, so it’s for experts only, but the wind is correct, and the power is huge.

The last few days of the outlook see the swell dropping back down, with the SW groundswell returning. The energy is still strong, but the wave heights are small again. Nothing to get too excited about there.

So, in summary: the first week is a bust. The standout is Tuesday the 15th morning for the glassy conditions and solid waves. The other big days from the 16th to the 18th are for the big-wave chargers only, with the Thursday morning looking the best of that bunch thanks to the offshore wind.

Stay patient, and keep your eyes on that Tuesday glass-off.

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.
