Table - best surf conditions forecast for Narrabeen-Alley Rights over the next 16 days.
Right, Rusty here again. Let’s talk Narrabeen-Alley Rights in feet and miles per hour.
First up, it’s a slow start. Saturday the 11th has a weak 3ft ESE swell but a cross-shore breeze and not much energy (349). Sunday and Monday are flat – tiny, clean but no push. Not worth a paddle.
There’s a big dry spell until the second half of the week. Thursday the 16th afternoon sees a bump to 5ft from the SSE, but it’s cross-onshore and choppy. Ugly. Friday is messy too. Saturday the 18th offers 4ft to 5ft from the east, but winds are still crossing it up and energy is moderate (274-369). Still marginal.
Then Sunday the 19th morning – bingo. A clean 7ft E swell with a light offshore from the NW (508 energy) and clean conditions. That’s a proper session for experienced crew. Monday the 20th morning is even better: 7ft E swell, 11-second period, light offshore from the WNW, excellent conditions (1004 energy). That’s the highlight for the strong paddlers.
Tuesday the 21st pushes 8ft to 8ft but the cross-onshore wind starts to mess it up. Wednesday the 22nd morning cleans up with 6ft E swell and light cross-off winds. Thursday the 23rd morning fires: 7ft from the ESE, light cross-off, 11-second period, excellent conditions (1167). Thursday afternoon goes glassy with a 8ft ESE swell and zero wind – that’s magic but only for experts.
Friday the 24th morning is the biggest – 8ft from the SSE, 13-second period (2745 energy), clean, but only for the brave. Afternoon hits 10ft from the SE, which is just too big for this bank. Saturday the 25th drops back to 5ft-6ft with onshore winds.
Best sessions are Sunday the 19th morning, Monday the 20th morning, and Thursday the 23rd morning. The standout is Thursday the 23rd morning with glassy conditions and that solid 8ft groundswell.
Water temp is about 65°F, right on average for mid-July.
Expect company at Narrabeen-Alley Rights – crowds are common, but those clean windows are worth the squeeze.
Rusty.
