The Lowdown
Alright, family, Rusty here. Let’s talk about the next couple of weeks. It’s a bit of a mixed bag, with some clean windows trying to push through a whole lot of mush and onshore bump. We’ve got one stretch that’s really got my attention, but we’ve got to dig through some average days to get there.
The first few days are a write-off, to be honest. Friday looks like a classic junkyard – a bit of size at 6ft but with a cross-on breeze it’s just gonna be a mess. Saturday and Sunday are small and poor, with the swell energy dropping right off. We are looking at a couple of days with nothing worth paddling out for.
There’s a decent gap with no real recommendations through the middle of next week. It’s not until Thursday the 10th that things start to clean up, and that’s our first real highlight. Caspar Creek (Mendocino) is the only spot on the map, and it’s a sheltered little nook that doesn’t need a ton of juice. On Thursday morning we’ve got a 3ft SW groundswell with a long 17-second period, and a light cross-offshore breeze. It’s gonna be clean and lined up. The wave energy is moderate, around 593, which is plenty for that spot. It’s an inconsistent wave, so be patient between sets, but when they come, they’ll be worth it.
Friday the 11th the wind swings around to the south and messes it up, but then Saturday the 12th is another good one. Similar SW swell, around 3ft with that 14-second period, and again light cross-offshore conditions. This is another clean, workable day.
Then we have another little gap of average conditions until things turn interesting. The standout of the whole run, though, is shaping up for the morning of Sunday the 13th. The wind drops right out, we’re talking glassy conditions, and there’s a nice 4ft WNW swell with a 10-second period. The energy reading is 411, so it’s not massive, but it’s clean, and that’s what matters. This is the pick of the bunch – a proper Sunday morning glass-off.
After that, the second week gets a bit weaker and more disjointed. There’s another patchy stretch from Monday the 14th through Wednesday the 16th, with some tiny SW pulses and a lot of cross-onshore wind, not worth getting excited about. Thursday the 17th is a bit bigger, 3ft, but still just okay.
Now, the long-range stuff is promising but far from certain. By Friday the 18th we’re looking at a serious jump in size – 7ft early, but the period is short and junky. It builds through the afternoon to a powerful 10ft by the end of the day. The energy numbers are big, over 1500, but with a short 8-second period, it’s going to be a bit of a washing machine. The wind is light cross-onshore, so it might be big, but it’s not going to be clean. This one is for experts only, and even then, it could be a grinder. By Saturday the 19th, it’s still big at 8ft, but the quality is still poor.
All in all, the pick is that Sunday the 13th. It won’t be huge, but it’ll be clean, glassy, and fun. The Thursday the 10th and Saturday the 12th are solid backup days too. That big swell at the end is just too messy to call, and we’ll have to see how it sorts itself out.
Alright, stay stoked.
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.
