The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the Gisborne region over the next couple of weeks.
We’re kicking off with a bit of a slow start. The first real standout is Saturday morning, 18 July at Wainui Beach - Stockroute. The swell is coming in from the ESE at 4ft, with a long period of 14 seconds pushing that groundswell energy into the beach and reef setup. The wind is light offshore from the WNW, and the water temp is sitting at 57°, which is about normal for this time of year. That combined energy reading is a solid 1015, which is moderate, but with the glassy conditions, this is the cleanest session on offer early on. It’s a spot that handles the SSE optimum swell direction well, and the crowds are only sometimes an issue, so you should get a few waves to yourself.
Sunday morning, 19 July is a ripper. Swell jumps to 5ft from the SSE, with a very long period of 18 seconds. That’s proper groundswell energy, and the combined energy is a strong 1734. The WNW offshore wind is light again, making it clean. This is the best of the bunch for experienced surfers. That long period at a beach-and-reef setup can make it a bit straight, but the quality is there.
Tuesday, 21 July is another gem. The morning session is glassy, with zero wind, and a solid 6ft SSE swell at 16 seconds. The combined energy is 1535, so strong. That afternoon is also glassy, with the swell holding at 5ft. This is the kind of day you wait for.
Monday morning, 27 July sees a new pulse of swell from the SE at 3ft, period 12 seconds, with a gentle offshore wind. The combined energy is 417, moderate, but it’s clean.
Tuesday morning, 28 July is a standout for the second week. Swell is 6ft from the SE, but the period is only 8 seconds – a short period windswell. The combined energy is 664, moderate, and the wind is moderate offshore from the NW. The water is clean, and it’s worth a look for a bit of punchy, fun surf.
There’s a gap from the 22nd through the 26th where the swell drops and the wind goes messy, with only tiny, weak waves. The 3ft on the 27th is the first real return.
Overall, the best on offer is Sunday morning, 19 July for the size and quality, and Tuesday, 21 July for the glassy, clean conditions. The water is about average for the season, and the long period swells favour the reef sections at Wainui.
Rusty.
