The Lowdown

Alright folks, Rusty here. Let's have a look at what's cookin' at Chadbourne Gulch over the next couple of weeks.

Honestly, it's a bit of a mixed bag. We've got some serious size coming through at times, but the wind and conditions are gonna make you work for it. The water's sitting at 59°, which is pretty much spot on for this time of year.

We kick off this Sunday afternoon with a cross-on breeze out of the NW at 12 mph and a 5 ft NW swell. It's gonna be choppy, so don't expect much. Monday morning is similar but lighter wind with a 6 ft swell, still cross-on and only marginal. Monday afternoon though, things get heavy. The swell jumps to a solid 10 ft from the NW, and even though the wind is light, it's cross-on and the energy is pumping. That's expert territory – way too much power for most of us, so unless you're really savvy, give it a miss.

Tuesday morning (15th) sees the swell drop back to 6 ft with a light west wind going offshore. That's the first glimmer of hope. It's still a bit questionable on the tide, but it's better. Tuesday afternoon has similar vibes, 7 ft but with a bit of cloud and a light cross-on breeze. Wednesday continues the trend with 6 ft to 7 ft, but the wind stays cross-on.

Now, Thursday the 17th afternoon is interesting. The swell drops right off to 2 ft, but it swings to the SSW with a very long 16-second period and glassy conditions. The combined energy is still moderate, but that period is beautiful. You'll be waiting for sets, but if you get one, it'll be a clean, long wall.

From Friday the 18th right through to Sunday the 21st, we are in a lull. The swell is tiny, 2 ft to 3 ft, from the SW with those long periods (17-19 seconds). It's not breaking with any power on this beach setup, and the wind is mostly cross-on or offshore light. It's a quiet spell.

Then comes Monday the 21st afternoon – hang on. An 8 ft NW swell rolls in with the wind going glassy and calm. The note says excellent for experienced surfers, and they're right. That's a lot of water moving, but with that glassy surface it'll be clean for those who can handle it.

Tuesday the 22nd keeps the size at 8 ft to 8 ft from the NW, but the wind is back on or cross-on, so it's gonna be bumpy. Wednesday the 23rd afternoon is another standout though. 8 ft from the NW with a 9-second period, and the wind goes completely glassy. That's a proper afternoon session for the experienced crew.

Thursday the 24th afternoon gets huge again – 10 ft from the NW, glassy winds, but it's flagged as too big for this break. That's a hard pass. Friday the 25th sees a drop back to 7 ft from the NW, offshore wind in the morning, but the energy is dropping.

The last few days from the 26th to the 28th are a write-off. The wind picks up strong, 16-22 mph from the NW, making it choppy and lumpy. Even when there's size on the 28th (10 ft), it's just a mess. This setup looks more interesting for kite surfing than paddle surfing those last few days.

So, if I had to pick the best on offer, it's a tie between Monday the 21st afternoon and Wednesday the 23rd afternoon. Both have solid NW swell and glassy conditions – that's the clean, powerful stuff you want. The rest is a waiting game or for the die-hards.

Rusty out.

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 Chadbourne Gulch 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.
