Caspar Creek Surf Forecast and Surf Report

Alright folks, Rusty here. Gotta be straight with you – the outlook for Caspar Creek over the next 16 days is a tough one. It’s a sheltered beginner-friendly spot, and it’s going to need a whole lot of things to line up to be any good. The truth is, for the first week and a half, the conditions are just plain ordinary, with onshore winds and messy surf. The real standout, and I mean the only one worth circling on the calendar, is the morning of the 11th of September. Otherwise, we’re looking at a long stretch of frustrating not-much.

Let's run through it. Right now, through the end of August, we’ve got solid swell but it’s blown out. Sunday morning has a 6ft NW swell but with a cross-onshore breeze, making for a rough surface. Afternoon gets even windier. Monday and Tuesday keep the onshore flow but the swell drops off. The combined wave energy is moderate early on, at 424 on Sunday morning, but it’s just not clean.

Then we hit a real lull. From the 1st of September all the way through to the 10th, it’s a mix of tiny swell, wrong wind directions, and barely any energy. The combined swell energy dips well into the double digits on the 1st and 2nd, hovering around 109 to 350 – weak stuff. There’s a tease of a long-period 18-second groundswell on Wednesday the 2nd, with 350 energy, but it’s cross-shore wind and only 2ft. Not for paddling; the conditions are too choppy. A couple of mornings around the 6th and 7th go glassy, with 3ft to 3ft swells, but the periods are short and the wave quality is described as very ordinary. That’s about as good as it gets for that whole block.

Now, the morning of the 11th of September is our one true standout. The forecast shows a 3ft swell from the SW, with a long 16-second period. That’s groundswell, folks – real energy. The combined swell energy hits a strong 854. More importantly, the wind swings to a light cross-offshore from the SSE, which will groom the faces. The report says it’s "clean." For Caspar Creek, which can handle a south-west groundswell, this is the moment. However, don’t expect perfection – the swell’s not huge, so quality over quantity.

After that, we’re right back into the wind. The afternoon of the 11th sees a bigger 8ft NW swell, but it goes cross-on again. That 8ft is big enough for experts only, but with poor wind, it’s a mess. The 12th and 13th of September stay windy and cross-onshore, with the 13th afternoon getting up to 12 mph winds. A 5ft swell on the 13th morning has a nice 11-second period, but the chop will make it a battle.

Caspar Creek is a consistent spot for swell, but the wind and tide issues are going to keep it locked up for almost the whole run. The water temp is about average for this time of year, nothing weird. So, yeah, keep the 11th of September morning in mind. It’s a long wait, but that’s the only window for a clean wave here.

Rusty.
