The Lowdown
Alright, let’s switch to feet and degrees for you imperial crew.
This forecast is a slow burner, no two ways about it. The next week or so is mostly flat and frustrating, but we do get a couple of moments where the ocean wakes up.
The real action starts to show on Saturday morning, August 1st. Swell swings around from the SSE about 5ft, and by the afternoon it goes glassy with a light ESE breeze. That means Narrabeen-Alley Rights will be smooth, clean, and surprisingly fun as the evening sets in. That’s your first real chance.
Sunday morning, August 2nd, is the standout by far. The SSE swell holds at 5ft, but the period stretches out to 13 seconds, which is proper groundswell with decent power. The combined energy reads 999, which is moderate to strong, and with a light N breeze the waves will be clean and well-shaped. Water temperature is 64°, bang on average for this time of year. The break is exposed, very consistent, and it’s set to be the best session in the whole window. Expect company though—crowds are likely.
Monday the 3rd is still worth a look in the morning—3ft with offshore NNW wind—but after that, from Tuesday the 4th right through until about Friday the 14th, it’s dead. We’re talking days of tiny surf, under 3ft, with barely any energy. A few clean mornings but nothing to write home about.
Now, way out on Saturday, August 15th, the models show a monster. A 16ft SSE swell with a 11-second period and a combined energy of 6002. That is a beast. The wind will be light from the north, so it will look clean and inviting... but that size at a beach/sandbar is strictly for experts. Way too big for beginners, and even experienced surfers need to be wary. Long-period groundswell like that can break super straight on the beach—not an easy paddle.
So here’s the short version: next weekend is your window, Sunday the 2nd morning is the real winner. After that, it’s flat for a long stretch, then the middle of August throws a massive, dangerous swell at us. Keep your head up and your eyes on the water.
Take it easy.
