The Lowdown
Alright, let me break this down for you.
We’ve got a mixed bag coming up at Akabane Long Beach. The week starts off pretty average, with a few sessions that might tempt you if you’re desperate, but nothing to write home about. The water’s sitting at 78°, which is a bit colder than normal for this time of year – you might want a thin spring suit.
Tuesday the 15th starts with a risk of t-storms and a cross breeze from the East at 12 mph. Swell is 4 ft from the SE with a short period, and the energy is weak (263). That’s a no-go for now. But hold up – Tuesday afternoon brings a total switch: the wind goes glassy from the NNE at just 3 mph, and the swell picks up slightly to 4 ft from the SE. It’s not huge, but glassy conditions on a beach break? That’s a rare treat for a clean afternoon session. The combined energy is moderate (367), so you’ll get some fun little waves.
Wednesday morning is clean with light offshore flow, but the swell drops to 3 ft (180 energy). Surfable but ordinary. Wednesday afternoon gets choppy – cross-onshore around 16 mph and the period drops to a shocking 5 seconds. Not worth the paddle.
Thursday and Friday stay mediocre – light winds but messy, onshore tendencies. The swell hangs around 4 ft to 5 ft but with short period and poor quality. The energy stays weak to moderate (141 to 463). Leave the board at home.
Now, Saturday the 19th – that’s the first real standout. The morning brings a solid 8 ft SE groundswell with a long 14-second period. The wind is light and cross-offshore from the NNE at 3 mph. That’s clean, powerful, and the energy is pumping (2705). This is excellent for experienced surfers – it’s too big for beginners. The afternoon gets even bigger at 10 ft (2565 energy), but the wind stays light. If you’ve got the skills, Saturday morning is the call.
Sunday the 20th keeps the quality going: another 8 ft SE swell in the morning with cross-offshore winds, and the afternoon pushes 10 ft from the SSE with clean conditions. Energy is very strong (2365-2919). Crowds are often here, so expect company for these sessions.
Monday the 21st pumps hard with 10 ft to 12 ft S swell, long 14-second period, but the wind gets fresh from the East (12-19 mph), cross-shore and lumpy. Energy is massive (4237-5496). This is expert territory only – and the chop will make it a battle. Might be better for kitesurfing than paddling.
Tuesday the 22nd – this one is insane. 28 ft of SSE swell with a very long 16-second period, but the wind is a near gale from the East at 34 mph in the morning, and a severe gale at 47 mph in the afternoon. The energy numbers are off the charts (35564 and 22915). This is purely for kamikaze experts, or better yet, don’t go near the water. Kite surfers might have a field day if they’re crazy enough.
We then hit a dry spell from Wednesday the 23rd through Saturday the 27th morning. The swell drops back to 3 ft to 6 ft, mostly onshore and choppy, with weak energy. Nothing to get excited about.
But then Sunday the 27th afternoon shows promise – a 3 ft S swell with a long 14-second period, cross-offshore winds, clean and glassy. Energy is moderate (729). Not a standout but a solid sneaky session.
Monday the 28th – another highlight. Morning has 6 ft S swell, 14-second period, light offshore breeze, and the afternoon goes glassy with 6 ft. Energy is strong (1420 and 1280). Clean, rippable conditions for experienced surfers. This looks like the best of the second week.
Tuesday the 29th gets bigger at 8 ft to 8 ft with strong offshore winds, but the energy is high (2313-2648). It’s a expert-level, clean, powerful day.
Wednesday the 30th closes the window with 8 ft to 8 ft S swell, 15-second period, clean offshore winds, and very high energy (2681-2893). For experienced surfers, this is another banger.
Best on offer: Saturday the 19th morning for the combination of solid size, clean wind, and excellent energy. If that’s too big, Monday the 28th is your next best bet with glassy conditions and a more manageable size.
Signing off, Rusty.
