The Lowdown
Alright folks, Rusty here. We’ve got a 16-day look at what’s on offer for Caspar Creek, and I gotta be straight with you – this stretch looks pretty grim for the most part. We’ll see a few moments where you could get wet, but nothing’s shaping up as a standout.
The water temp is sitting at about 59°, which feels pretty standard for this time of year – nothing weird going on there.
Let’s talk about the first real chance. From the start, we’ve got some swell running, but the wind is a problem. Saturday the 8th has 6ft waves out of the NW with a short 7-second period, but it’s cross-onshore and choppy. The combined energy is weak, sitting at 369, so it’s not really doing anything for you. That pattern hangs around for days. Sunday the 9th bumps up to 8ft and 8ft, still NW, still cross-onshore, and the energy climbs to 1044 by the afternoon, which is getting stronger, but the wind just ruins it. Monday the 10th is more of the same, with 8ft waves and the same cross-onshore breeze.
It’s not until Wednesday afternoon the 12th that the wind finally swings onshore, light from the WNW at 3 mph, and we get a bit of relief. You’re looking at 7ft waves from the NW at 9 seconds, but the energy is moderate at 686, and the conditions are only marginal – questionable tide, but at least the wind isn't trashing it. Then Friday afternoon the 14th gives us the best we’re gonna see: glassy conditions, waves down to 4ft from the NW at 8 seconds, with a weak energy of 239. It’s surfable but very ordinary. I wouldn’t get too excited.
After that, it drops off fast. By Saturday the 15th and into the next week, the swell fades to under 3ft with very weak energy (in the double digits to low hundreds). The wind stays mostly cross-onshore or light, but there’s just no juice.
There’s a little pulse around Tuesday the 18th as a longer-period swell (15 seconds) shows up from the WNW, hitting 3ft to 4ft, but the energy picks up to 526. Problem is, the wind is a moderate cross-onshore at 12 mph, so it’s choppy and messy. That longer period would be a treat at a point break, but here it’s just not coming together.
Looking way ahead to Saturday the 22nd, the swell bumps back up to 6ft then 8ft on the afternoon from the NW, energy around 665 to 681, but again, the wind is cross-onshore and it’s only marginal at best.
Honestly, there’s no true standout session here. If you’re desperate, that Friday afternoon the 14th with glassy conditions and small waves is the cleanest you’ll see. But if the wind cooperates better on Wednesday the 12th, that could be a sneaky window. Otherwise, it’s a long stretch of poor conditions with a few marginal windows. Keep an eye on the forecasts – this area can change quick.
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.
