Nanarup Beach Surf Forecast and Surf Report

G’day, Rusty here. We’ve got a solid run of swell on the way for Nanarup Beach, but it’s a wild ride with plenty of size and some tricky wind windows. The water’s sitting at 64°, which is a touch warmer than normal for this time of year—nothing crazy, but you’ll notice it’s not as cold as it usually is.

The first real action kicks off on Wednesday afternoon, the 12th of August. A big 12 ft S swell rolls in, but with a 12 mph WSW cross-breeze and a period of 15 seconds, it’s going to be a bit of a mess. The combined energy is massive at 4739, but the cross-chop will make it ugly. This one’s for the experienced crew only, and even then, it’s marginal.

Clean up happens Thursday morning, the 13th. Swell drops to 10 ft from the SSW, but the period stretches to 16 seconds and the wind shifts to a light WNW cross-off, 6 mph. The water turns glassy, and the energy is still pumping at 5392. This is the standout of the whole run—big, clean, groundswell lines. That 16-second period means long waits between sets, but the waves will be powerful and well-shaped. The break is consistent and fairly exposed, so it’ll handle the size. Crowds are possible here, so get in early. For the experts, this is the session to circle.

Friday the 14th keeps it going with 8 ft SSW swell and a 16-second period, morning glass-off with a NNE cross-off at 6 mph. Clean again, energy sitting at 2829. Still good, but not as big as Thursday.

Saturday the 15th sees the swell ease to 5 ft, but the wind goes pure offshore from the NNW at 12 mph in the morning, dropping to a 3 mph N breeze in the afternoon. Energy drops to 967, but those offshore conditions will make the most of it. Clean, fun waves for the intermediate crowd.

Sunday the 16th and Monday the 17th keep the 5 ft swell going with a 16- to 18-second period. Sunday has a NNE cross-off all day, energy around 1300, while Monday brings a 16 mph N offshore in the morning, bumping energy to 1961. Both are clean, but the offshore on Monday will be a treat.

Things get messy from Tuesday the 18th through Friday the 21st. Cross-shore winds and lumpy conditions take over, with swell ranging from 4 ft to 7 ft. The energy fluctuates, but the quality is poor. Save your energy.

Saturday the 22nd brings a new pulse: 10 ft SSW swell, but it’s cross-shore all day with 12-16 mph WSW winds. Energy is 4096, but the chop will be nasty.

Now, the second week’s highlight. Sunday the 23rd and Monday the 24th look promising. Sunday morning has an 8 ft SSW swell, light N breeze at 3 mph, and a cross-off flow. Energy is 2895, and it’s clean. Monday afternoon is the real standout: 8 ft SSW swell, 15-second period, wind goes offshore from the N at 9 mph, and the energy jumps to 5162. That’s a massive pulse of clean, powerful groundswell. Again, this is for experienced surfers—over 8 ft, so it’s too big for beginners. The long period (15 seconds) means it’ll be a bit straighter at a beach break, but with offshore wind, it should still hold up.

After that, the swell fades quickly through the 25th to the 27th, with energy dropping below 1000 and wind staying cross-off. The last few days on the 27th have a 4 ft SSW swell and a 12 mph offshore from the NNW—clean, but small.

Overall, the best on offer is definitely Thursday morning the 13th and Monday afternoon the 24th. Both are clean, powerful, and for the experienced crew. Don’t sleep on them.

Rusty.
