The Lowdown
Alright folks, Rusty here. Let’s break it down.
The pattern for Te Oka Bay on Banks Peninsula is a real rollercoaster. We’ve got a solid, clean opener, then a stretch of junk, followed by some serious firepower in the second week. The first standout is tomorrow, Tuesday the 21st of July. We’re looking at a 5ft swell from the south with a 12-second period, pushing a moderate 642 units of energy. The wind is glassy out of the NNE at only 3 mph, so the surface is going to be like a mirror. Water temp is 50°, right where it should be for this time of year. This is your go-to day for a fun, clean session.
Don’t get too comfortable, though. Wednesday and Thursday drop off to under 3ft, and while the wind stays light, the energy just isn’t there. By Saturday the 25th, it’s a total mess. A strong SSW wind hits 19 mph, and we’re stuck with 10ft of short-period, lumpy cross-onshore junk. That’s unrideable. This nasty stretch drags through Sunday and Monday – the wind stays bad, and the swell is either too weak or too chopped up.
Now, here’s where it gets good. The first real standout is Tuesday morning the 28th of July. The swell jumps to 8ft from the ESE with a 14-second period, pumping a massive 2708 units of energy. The wind is light and cross-off from the NW at 6 mph, keeping the surface clean. That’s groundswell, and at that size, it’s expert territory. Beginners, stay on the beach. The longer period means proper lines, but it might be a bit shifty on the beach.
The next big window is the end of the month. Friday the 31st of July has a clean 6ft SE swell with a 13-second period, and the wind is light and cross-off. Saturday the 1st of August is even better: 5ft from the SE, and the wind goes offshore from the NNW at only 3 mph in the afternoon. Glassy. Clean. The energy is solid at 1357 units. That’s a long, quality session.
Things get rowdy again on Sunday, and by Monday the 3rd of August, the swell hits 15ft to 16ft from the SSW. That’s way too big for this break, even if the wind is perfect. That’s tow-in or kite-surf territory. The good news is that by Tuesday afternoon the 4th, the swell drops to 10ft, and by Wednesday the 5th, we’re back in the sweet spot with 6ft from the SE, glassy conditions, and a 12-second period. Another excellent window for the experienced crew.
So, bottom line: tomorrow (Tuesday the 21st) is your early pick for clean fun. The real standout is Tuesday the 28th of July, and the weekend of the 31st of July through the 1st of August is a solid, reliable run of quality surf. The second week has promise, but as always, check the wind closer to the day.
Rusty.
