The Lowdown
Alright, let’s break this down for Tawharanui. Straight up, it’s a rough patch. There’s a big, empty gap at the start before we see anything worth talking about.
Starting Tuesday, July 14th, forget it. Rain showers, a cross-shore breeze, and a weak 1.0m north swell with no push. The combined energy is a measly 63. Wednesday and Thursday are even smaller, barely 0.3m. It looks clean in the mornings, but there’s no power.
Finally, on Friday, July 17th, a tiny pulse shows up. We get a 0.4m east swell, but the period stretches out to a super long 17 seconds, giving it some real weight. The combined energy hits 100 (moderate). Friday afternoon is the pick, with a clean offshore breeze from the southwest. Still small, but rideable.
Saturday the 18th is more of the same. Tiny 0.3m east swell with that long period. The morning is clean with a light cross-offshore breeze, and the afternoon swings offshore from the southwest again. For a beginner on a longboard, this is your window.
After that, it’s grim. From Sunday the 19th through the end of the month, it’s a steady stream of poor surf. Small, short-period windswell from the southeast and east, with cross-shore or cross-onshore winds making a mess of things. The combined energy jumps to 126 on the 24th and a moderate 233 on the 27th, but the wind is always on it or wrong, leaving it choppy and unrideable.
The highlight, if you can call it that, is Friday afternoon, July 17th at Tawharanui. That 0.4m east swell with the very long period will wrap nicely onto the reef. With that 12 mph southwest offshore wind, it’ll be glassy. The combined energy is moderate (87), so it’s got a bit of life. It’s beginner-friendly, and you might score it uncrowded, though it can get busy.
Bottom line: after that Friday session, you’re looking at over a week of nothing. A waiting game for sure.
