The Lowdown
Alright, let’s get into it. Straight up, this is a tough stretch for Narrabeen-Alley Rights. The first week is looking pretty flat or messy, so don't be in a rush to paddle out just yet. The real action is hiding in the second week.
For the first few days, from the 27th to the 31st, it’s all about tiny, weak waves. We’re talking ankle-snappers. The swell heights are barely a whisper at 0.3 ft to 1 ft, with very low combined energy (14 or less). The wind is mostly cross-off or clean, but there’s just no push in the ocean. It’s a write-off. You’ll be sitting out there staring at flat water.
We get a bit of a pulse on Saturday the 1st of August. The afternoon sees a jump to 4 ft from the SSE (combined energy 300), but it’s coming in with a cross-onshore wind. It’s going to be a little bumpy. You might find a wave, but it won’t be pretty.
Now, Sunday the 2nd of August is the first real chance. The morning session is your best bet. We’ve got a clean 4 ft SSE swell with a nice 10-second period, light offshore breeze from the north, and the combined energy is solid at 252. It’s not huge, but it’ll be clean and fun on the sandbar. The afternoon gets chopped up by a stronger north-easterly, so get out early.
The following week, Monday the 3rd to Friday the 7th, is a bit of a mixed bag. The swell drops back to 2 ft to 3 ft with weak energy (biggest reading is 108). The wind is mostly cross or cross-off, so it’s surfable but very ordinary. Nothing to get excited about.
Then we hit the big stuff. On Saturday the 8th of August, the ocean is going to fire up. The morning shows a massive 12 ft SE swell with a combined energy of 2736. The wind is light and offshore from the WSW – a dream lineup. But, and this is a big but, 12 ft is double overhead. Too big for beginners, and straight into expert territory. This is a beast. The afternoon stays big but gets a bit lumpy with a cross-onshore.
The standout, the one you’ve been waiting for, is Sunday the 9th of August, morning session. The swell drops to a still-serious 7 ft from the SE (combined energy 1018), with a perfect offshore wind from the NW. The period is 11 seconds, so it’s a proper groundswell with plenty of power. Conditions will be excellent for experienced surfers. This is the call. The afternoon gets messy again, so make the most of the morning glass.
Monday the 10th of August morning is still worth a look: 4 ft SE swell, offshore wind, combined energy 218. It’s a solid, clean wave. The rest of Monday and Tuesday the 11th see the wind pick up strong, with the swell dropping off and becoming disorganised, so the window is closing.
To wrap it up, the water is sitting at 64°, which is bang on average for this time of year. Expect crowds at Narrabeen-Alley Rights, it’s a popular spot.
The best on offer is hands down Sunday the 9th of August morning. The 7 ft SE groundswell with offshore winds will be clean, powerful, and a proper session for the experienced crew. The Saturday morning before it is a monster, but only for the big wave specialists.
