Table - best surf conditions forecast for Narrabeen-Alley Rights over the next 16 days.
Alright, grab a coffee, 'cause we've got a bit of a mixed bag coming our way. The action starts Thursday the 9th of July, but honestly, it's not much to write home about. We're looking at a 6ft swell from the SE with a 10-second period, but the wind is a problem. Morning has a light cross-shore, but the afternoon turns into a full onshore mess. The wave energy is moderate (783), but the whole thing is a bit of a write-off with that onshore wind.
Friday the 10th is where it starts to get interesting. That same 6ft SE swell is still rolling in, but the wind is much better. Morning sees a light cross-offshore breeze from the WSW, and by the afternoon it goes glassy with a SSW wind. That's going to be clean. The wave energy is still moderate (580), and for the advanced crew at Narrabeen-Alley Rights, this is your window. It's a beach/sandbar setup that's very consistent, and with the wind going glassy, you're in for a treat. The water temp is about 65°, which is pretty average for this time of year.
Saturday the 11th is a step down in size, dropping to 3ft from the ESE, but it's still got a decent 12-second period. The morning has a light offshore from the NW, making for clean conditions. It's not a standout, but it'll be a fun, smaller session.
Then we hit a long dry spell. From Sunday the 12th all the way through to Wednesday the 15th, the swell dies off completely. We're talking tiny waves, flat spells, and the occasional strong wind. It's a proper lull.
Now, here's where it gets a bit wild. Thursday the 16th of July, the models are showing a big spike in swell, hitting 13ft from the SSE. But don't get too excited. The period is only 10 seconds, and the wind is a strong onshore breeze from the SSE. That's a recipe for a closeout, dangerous mess. The wave energy is strong (2895), but with those conditions, it's a no-go for a paddle. Honestly, this setup looks more interesting for kite surfing than paddle surfing.
Friday the 17th and Saturday the 18th keep the size up, but the wind stays onshore. We're talking 11ft to 10ft of SE swell, but with onshore winds, it's going to be raw and ugly. The wave energy remains very strong (2554-1830). This is expert-only territory, and even then, it's going to be a battle.
Things start to settle down by Sunday the 19th, with the swell dropping to 6ft, but the wind is still cross or cross-onshore, keeping the quality marginal. The energy drops back to moderate (766).
Into the second week, from Monday the 20th onward, the swell fades out again. We get a few small pulses of 5ft or 3ft, but the wind is all over the place. The last real chance for a wave is the morning of Tuesday the 21st, with a tiny 3ft ESE swell and glassy conditions, but it's just a small, surfable wave. After that, it's back to flatness.
So, the best bet by far is Friday the 10th of July at Narrabeen-Alley Rights. The 6ft SE swell, combined with that glassy afternoon wind, is going to give you the cleanest, most fun waves of the whole forecast. Don't sleep on it.
