The Lowdown
Alright, let’s get into it. We’re looking at Wainui Bay Chalet, the only spot in the forecast for the next 16 days. Straight up, Friday morning the 17th of July is the pick. There’s a 5ft groundswell from the ESE, period hanging at 16 seconds – that’s proper long-period juice. The combined energy is 1060 (moderate to strong), and with a light offshore from the WNW, it’s going to be clean. This is an exposed spot, so it’ll handle that swell, but groundswell this long can make the peak a bit racey at a beach break. For experienced surfers, this is the best of the bunch.
Water temp is about normal for the season.
Saturday morning the 18th is still good. 4ft, same ESE direction, 14 seconds, and another clean offshore. Energy is a bit lower at 956, but still a fun wave. Sunday morning the 19th sees the swell switch to the SSE with a 19-second period and energy jumping to 1795 (strong). That’s a big, powerful swell. The wind is a light cross-off, so it’s workable, but these long-period swells can stand up fast and close out. If you’re experienced, it’s a blast.
Monday the 20th morning is clean again – 4ft, SSE, 15 seconds, offshore. A nice cruisy day. Then Tuesday the 21st is a story of two halves: the morning is a mess with onshore rain and bumpy conditions, but Tuesday afternoon turns glassy. The swell is 5ft, 16 seconds from the SSE, energy at 1110. That afternoon session is a gem for anyone who can get out.
After that, the size drops. Wednesday the 22nd and Thursday the 23rd have smaller but clean windows, down to 3ft and 4ft, but the period tanks, especially Thursday with a short 6-second windswell. Just ordinary. Then we hit a real dry spell. From Friday the 24th through the end of the month, it’s mostly small, weak, and messy. A few clean mornings pop up, like the 26th and 28th, with 2ft to 4ft, but energy is under 300 and the direction is all over the place. Nothing to get your hopes up for.
The start of August looks thin. The 1st of August morning has a tiny 3ft ESE swell, 14 seconds, a clean window, but it’s a shadow of that first weekend. The long-range stuff is promising but you’d be betting on a change.
Bottom line: Friday morning the 17th and Tuesday afternoon the 21st are your standout sessions. After that, it’s a lot of waiting for a small clean window.
