The Lowdown

G’day, Rusty here, and I’ve got a look at what’s coming up for Narrabeen-Alley Rights. This is one of those stretches where the surf is going to be pretty quiet for a while, so don’t get your hopes up too early. The water temp is sitting at 64°, which is about average for this time of year, nothing unusual there.

The first bit of action we see is Tuesday afternoon, the 8th of September. There’s a 7 ft swell out of the SSE, but it’s coming in with a short period of 8 seconds and a light SE breeze that’s onshore. The combined energy is moderate at 546, but the conditions are described as marginal, and the score reflects that. Honestly, it’s not worth paddling out for.

From Wednesday the 9th right through to Monday the 21st of September, it’s a long, flat run of poor surf. The swell heights stay tiny, often under 3 ft, with periods that are either too short or too long to do much good. The wind is mostly onshore or cross-shore, and the combined energy stays in the low double digits or barely reaches triple digits – we’re talking numbers like 58, 29, 27, 12, 38, 20, 19, 29, 11, 60, 45, 44, 131, 30, 135, 18, 2, 35, 26, 26, 21, 18, 123, 135, 32, 39, 90, 24, 23. It’s just not happening. There are a few moments with glassy conditions – like Saturday morning the 12th and Wednesday morning the 16th – but the swell is so small (0.7 ft and 4 ft respectively) that it’s barely a ripple. The 16th has a 4 ft SSE swell with a 7-second period and glassy wind, but it’s still “very ordinary” at best.

The standout window, if you can call it that, is on Wednesday the 16th of September in the morning. That 4 ft SSE swell with glassy conditions is the cleanest we’ll see, but the size is tiny and the period is short. It’s not a day to get excited about, but it’s the only time the wind lines up with any wave at all.

Later on, Wednesday the 18th of September in the afternoon has a 1 ft SSE swell with a very long period of 18 seconds and glassy conditions. The combined energy is 135, which is moderate, but the swell is so small it’s barely surfable. That long period suggests it’ll be a groundswell, but at this size, it’s more of a wobbly line than a wave.

Overall, this is a tough stretch for Narrabeen-Alley Rights. The beach/sandbar setup is exposed, but the swell just isn’t delivering. With the wind often messy and the sizes tiny, this might be more interesting for kite surfers on the days when the wind picks up, but for paddle surfing, it’s a blank run. The crowds are often around here, but they won’t be a problem because nobody’s out. Don’t write it off completely – forecasts can change, and it tends not to stay this quiet for long.

Information about the Narrabeen-Alley Rights Surf forecast

The above surf forecast table for Narrabeen-Alley Rights provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Narrabeen-Alley Rights can be found by selecting the local surf guide option on the grey menu. Our Narrabeen-Alley Rights surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Narrabeen-Alley Rights) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
