The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the table for the next couple of weeks.
Overall, it's a pretty quiet run for the most part, with a small window of decent surf early in the week. The standout is definitely Monday morning the 20th of July. After that, the swell drops away and we're looking at a long stretch of tiny, poor conditions right through to the start of August, before a bit of a pulse tries to show up on the 3rd of August, but it's not looking great.
The pick of the forecast is Narrabeen-Alley Rights, a beach/sandbar setup for advanced surfers. The water temperature is sitting at 64°, which is pretty much normal for the time of year.
Let's start with the best of it. Monday morning the 20th of July is your call. The swell is coming from the ENE at 6 ft, with a period of 11 seconds, giving it decent groundswell energy. The combined energy is moderate to strong (1098), and with a light WNW wind blowing cross-offshore, it's going to be clean. The swell direction is right on the optimum for this spot. This is the best surf on offer, no question.
Tuesday morning the 21st of July is still surfable, with a 5 ft ENE swell and a 10-second period. The combined energy is moderate (433), and with a light northerly cross-offshore breeze, it should be clean. It's a step down from Monday, but still a solid session.
From Tuesday afternoon onwards, the swell drops and the quality goes with it. The wind swings around, and for the rest of July and into the first week of August, we're looking at a lot of tiny, weak waves. The combined energy drops to low double digits and even single digits, with heights under 3 ft. There's a long stretch of days with poor surf conditions, with the swell bottoming out towards the end of the month.
There's a hint of a new swell on Monday the 3rd of August, with a SSE swell pushing up to 4 ft and a period of 11 seconds. The combined energy is moderate (442), but the wind is onshore from the South-South-West and moderate, creating a cross-chop and poor conditions. It's not a standout, but it's the only pulse of size in the second week. It's a long way off, so keep an eye on it.
Rusty.
