The Lowdown

G’day, Rusty here. Let’s have a look at what’s coming up for Chadbourne Gulch.

Right off the bat, Thursday the 10th kicks things off with a 3ft SW swell, 17-second period – that’s a long-period groundswell, lots of energy – and combined swell energy is moderate at (835). Water temp is 59°, which is pretty normal for this time of year. Wind is light cross-on from the WNW, so it’s clean enough but not perfect. Wind’s light cross-onshore, so a few ripples but it’s rideable. This is a beginner-friendly spot, so that small, cleanish swell could be okay for a learner, but overall it’s pretty marginal.

Friday the 11th is much the same story: Friday morning has a 4ft SW swell, 16 seconds, with light offshore from the WNW – that’s a big positive. Light offshore wind will make for clean faces. Friday afternoon, the swell drops a touch to 3ft, still SW, 15 seconds, but wind swings to a light cross-on again.

Saturday the 12th: morning is 3ft SW, 14 seconds, light cross-on – still small. Afternoon goes downhill: 3ft SW, 14 seconds, but wind picks up to 12 mph from the NW, cross-on, and it gets choppy. Score says poor. That one’s a write-off.

Sunday the 13th: morning has a 4ft NW swell, 10 seconds – not great period – light cross-on, but it’s still choppy for the morning. Then Sunday afternoon gets messy: 7ft NW swell, short 7-second period, strong cross-on wind at 12 mph, combined energy (638). This is poor, choppy, and the swell’s getting big for a beginner spot like this. Not a good session.

Monday the 14th: morning is 7ft NW, 8 seconds, light cross-on. Still marginal. But Monday afternoon is a standout for the first week. Swell jumps to 10ft from the NW, 8-second period – that’s big, and combined energy hits (1288), which is strong. However, for Chadbourne Gulch, a 10ft swell is too big for most, and the note says the break can’t handle it. This is really for experts only, and even then, it’s a short-period NW swell, so it’ll be a bit sloppy. Wind is a gentle cross-on, so it’s not clean. This is more interesting for kite surfing than paddle surfing, honestly.

Tuesday the 15th: morning 6ft NW, 8 seconds, light offshore – that’s better for a paddle, but still short period and only marginal. Afternoon 7ft NW, 8 seconds, light cross-on.

Wednesday the 16th: morning 5ft NW, 8 seconds, light offshore – slight improvement. Afternoon 4ft NW, 8 seconds, light cross-on.

Thursday the 17th: morning sees a new swell – 2ft S, 16 seconds – very small but long period. Light cross-on. Still marginal. But Thursday afternoon is a little gem: 2ft from the SSW, 16 seconds, and it’s glassy. Light wind, no ripples. Expect good surf conditions. That’s clean and fun for a small longboard.

Now into the second week, things settle into a nice rhythm. The best stretch is coming.

Friday the 18th: morning 2ft SW, 19 seconds – very long period – light offshore. Marginal but promising. Friday afternoon: 2ft SW, 19 seconds, glassy. Expect very good surf conditions. This is clean, long-period, small but delicious.

Saturday the 19th: Saturday morning 2ft SW, 18 seconds, glassy again. Expect very good surf. This is a true standout. Small groundswell, long period, clean as a whistle. Amazing for a longboard or a funboard. Crowds are sometimes an issue here, so keep that in mind. Afternoon gets a light cross-on.

Sunday the 20th: morning 3ft SW, 18 seconds, light offshore – clean. Afternoon light cross-on but still small.

Monday the 21st: Monday afternoon is a beauty – 3ft SW, 17 seconds, glassy. Expect very good surf. Another standout window.

Tuesday the 22nd: Tuesday afternoon gets the best – 3ft SW, 16 seconds, completely glassy with zero wind. Expect very good surf. Perfect glass-off.

Wednesday the 23rd: morning jumps to 5ft NW, 10 seconds – bigger but less period. Marginal. Wednesday afternoon is back to 3ft SSW, 15 seconds, glassy – very good again.

Thursday the 24th: afternoon 3ft SSW, 14 seconds, glassy – expect very good.

Friday the 25th: afternoon 3ft SSW, 14 seconds, light cross-on – just marginal.

Overall, the best on offer is the glassy, long-period SW swells from Friday the 18th afternoon through to Tuesday the 22nd afternoon. That’s your pick. The spot is fairly consistent and has a beginner-friendly vibe, so these small clean days are perfect.

Rusty.

A general guide to surfing at Chadbourne Gulch can be found by selecting the local surf guide option on the grey menu.

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.
