The Lowdown

G'day, I'm Rusty. Look, I've got to be straight with you – the next 16 days are a real struggle around here. There's no classic groundswell or clean standout session to get excited about. The energy is weak, and the wind is all over the place. We're looking at a long stretch of tiny, messy waves.

Let's start with the only break on the radar: Narrabeen-Alley Rights. It's a beach/sandbar setup, exposed to the swell, but it's not doing us any favours. The water temp is sitting around 64°F, which is about average for this time of year.

From Wednesday the 9th to Saturday the 12th of September, it's a write-off. We're talking wave heights of 0.7 ft to 2 ft, mostly from the SE or ENE, with periods that are either too short (7 seconds) or long (14-15 seconds) for a beachbreak to shape up properly. The combined swell energy is a measly 19 to 58 (weak). The wind is cross or cross-on, with a strong breeze on Wednesday afternoon – total slop.

Sunday the 13th offers a slight glimmer. The morning is clean with a light cross-offshore breeze from the NNE, but the swell is still a pathetic 0.7 ft from the ENE with a 13-second period. That long period on a beach break means it'll break straight and close out. The afternoon brings a bit more size – 4 ft from the NE – but the period drops to a terrible 4 seconds, and the wind goes cross. It's a mess.

The second week is more of the same. Monday the 14th has a 'surfable waves' tag for the morning, with 2 ft from the NE and a 6-second period, but the energy is still weak (50). The wind is light and cross-off, so it's clean, but the waves are tiny and weak. By Tuesday the 15th, the wind swings to the SSE and freshens up, making it lumpy and cross-on.

The only real bump in energy comes right at the end of the forecast. On Wednesday the 23rd of September, the swell pushes to 4 ft from the NE with a 7-second period, and the combined energy jumps to 270 (moderate). The morning is clean with a light cross breeze from the NE. But it's still a short-period, wind-affected swell, and the rating is just 'marginal'. The following day, the 24th, brings a similar amount of swell (5 ft) but with a strong cross-onshore wind from the SSW and rain showers – nasty.

To be honest, for this entire 16-day window, there's nothing I'd call a standout. The best you'll get is a small, clean window on Monday the 14th morning, or maybe that slightly bigger but messy swell on the 23rd. Don't expect much. If you're desperate for a paddle, the 14th morning is your best bet, but keep expectations on the floor.

Rusty.

A general guide to surfing at Narrabeen-Alley Rights can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Narrabeen-Alley Rights may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
