The Lowdown

G'day, I'm Rusty. Let's have a look at the surf ahead for Wainui Beach - Stockroute. Over the next couple of weeks, there's a lot of size on offer, but the wind and conditions are going to be a real mixed bag, so we've got to pick our moments.

Right now, the water's sitting at 55°F, which is a bit colder than normal for this time of year. That's notable, so bring an extra layer if you're heading out. This is a beach and reef setup, exposed to swell, so it can handle the size, but it's advanced territory in the bigger stuff.

First up, Monday the 27th of July. The morning session is the pick of the two, with a clean 4.3ft swell from ESE at a long 13 seconds, and a cross-off wind from the WSW at 12 mph. The combined energy is strong at 1129, and with that clean face, you'll find some decent lines, but the report says it's marginal, so don't expect perfection. The afternoon jumps to 8.2ft from the S, period drops to 9 seconds, and the wind picks up to a fresh 19 mph cross-off. That's a bit more power, but the shorter period makes it messier.

Tuesday the 28th starts with a clean 6.9ft SE groundswell at 13 seconds, and a gentle 9 mph cross-off from the SW. The energy is still strong at 2057. It's marginal though, and the afternoon turns to a 6.6ft ESE swell at 13 seconds, but with a cross wind at 12 mph from the SSW, bringing a cross-chop. Not the best.

Now, Wednesday the 29th of July early morning is the first real standout of the forecast. We've got a 5.6ft ESE groundswell at 13 seconds, and the wind is pure offshore from the WNW, only 6 mph. Light breeze, clean, and the energy is a solid 920. The report says to expect very good surf conditions, and with that offshore wind cleaning it right up, this is the session to circle on your calendar. Crowds are possible here, so get in early. The afternoon gets messy with a cross-onshore.

Thursday the 30th morning stays clean with a 4.3ft ESE swell at 12 seconds and a cross-off from the NW at 9 mph. Energy is moderate at 507. Afternoon sees the swell drop to 3.9ft and the wind picks up a little.

Friday the 31st of July is a write-off, with a small 3.0ft ESE swell and a cross wind making it choppy. The morning has light rain too. Not worth paddling out.

Saturday the 1st of August morning is tiny, only 1.6ft from the SE with a long 16-second period, but the energy is weak at 197. The afternoon though, watch out. It jumps to 9.8ft SSE swell at 11 seconds, but a fresh 19 mph SSW cross wind is going to make it a lumpy, choppy mess. Not for paddle surfing, but the kite crew might have a look.

Sunday the 2nd of August morning has a 7.2ft SSE groundswell at 12 seconds, clean with a fresh 19 mph cross-off from the SW. Energy is strong at 1507. The afternoon picks up to 9.8ft from the SSE, same period, but the wind hits 25 mph. Too big and too windy for a good surf.

Monday the 3rd of August is a solid no-go. Swell hits 14.8ft from the S, with a near gale cross wind. Combined energy is a massive 10872. That's dangerous and messy. Stay on the beach.

Tuesday the 4th of August morning is another standout for the experienced surfers. The swell drops to 7.2ft from the SE at 13 seconds, and the wind is a light 6 mph cross-off from the W. The energy is still strong at 1709, and the conditions are clean. This is excellent for those who can handle the size. The afternoon drops slightly to 5.9ft but the cross wind comes in.

Wednesday the 5th of August morning is clean with a 4.3ft SE groundswell at 13 seconds and a gentle 9 mph cross-off. Energy is moderate at 594. Not a standout but a solid option.

Thursday the 6th of August morning is big again, 11.5ft from the SSW at 11 seconds, clean with a gentle 9 mph cross-off. The energy is very strong at 3939. The report says it might be too big for this break, so only the experts need apply.
