The Lowdown
Alright, this is Rusty, and I’m looking at the next couple of weeks on the West Coast. We’ve got a solid run of groundswell coming in, but it’s not all going to be clean. Let’s get into it.
The first week kicks off with a bit of a messy start. The swell is there, but that NE wind is killing the vibe. The best bet early on is Sunday afternoon: a 6.2ft NW swell, 10-second period, with light ENE cross-off winds. The wave energy is still getting into its stride (1178), but it’s clean. Monday is a washout with that 2.6ft WSW swell, 16-second period, but the wind is wrong, and it’s just not happening.
Things start to look up on Tuesday morning. The swell drops to 3.3ft, but the period is a solid 14 seconds from the WSW, and we get light ENE cross-off winds. The combined energy is moderate (478), and it’s clean. That’s the pick of the early week. The long period means the sets will be spaced out, but the shape at Manu Bay should be good.
The real standout, though, is the weekend of the 16th and 17th. Sunday morning the 16th is firing. We’re looking at a 6.9ft WSW swell, 16-second period, light SSE offshore winds. The energy is strong (2635), and the description says it’s excellent for experienced surfers. That’s the one. It’s a bit too big for beginners, but for anyone who knows what they’re doing, that’s the session to aim for. Monday morning the 17th holds similar size (6.9ft) and period (16 seconds), with light SSW cross-off winds, and the energy is still strong (2115).
We get another window on the 19th. Wednesday morning shows a 7.9ft WSW swell, 11-second period, with light S cross-off winds. The energy is strong (1407), and it’s clean. The 19th afternoon is also a cracker: 7.2ft, 15-second period, light S cross-off, with strong energy (2066). Both of these are excellent for experienced surfers.
After that, the swell starts to back off. The 20th through the 22nd have smaller, cleaner waves, with the 21st Friday morning being a nice 4.3ft, 16-second groundswell with light E cross-off winds. The 22nd Saturday morning has offshore winds from the ESE, pushing a 3.3ft, 14-second swell. The energy is weak (378), but it’ll be clean and fun.
The last few days of the forecast, from the 23rd, look poor. The wind swings onshore and the swell drops right off. The 24th Monday is a total write-off.
So, if you’ve got a session to pick, the 16th Sunday morning is your absolute winner. The 19th Wednesday morning is a close second. Both are solid, clean groundswell for the experienced crew.
Stay stoked.
