The Lowdown
Right then, let’s have a look at what’s on offer for the next couple of weeks. The only spot firing up is Dumps (Brandon Bay), so we’ll be sticking with it.
We’re starting off with a bit of a flat spell, no real surf to speak of. Sunday the 23rd is a write-off with tiny 1 ft NW swell and poor conditions. Monday the 24th is where things finally turn. The morning brings a clean 4 ft NW groundswell, period of 11 seconds, and glassy offshore ESE wind at 6 mph. The combined energy is moderate (337), and the water temp is about average for the time of year. This is the standout session of the whole run – that’s the one to get out for. The break is fairly consistent, so you can expect a few sets. Crowds are possible, but on a Monday morning they might be manageable.
The rest of the week is a mixed bag. Tuesday the 25th has clean but ordinary 3 ft W swell, with offshore winds again, but it lacks the punch of Monday. Wednesday the 26th is tiny and glassy in the morning, but only 2 ft. Thursday the 27th has a clean 3 ft WNW swell but gets blown out by the afternoon.
Friday the 28th sees a jump in size with 8 ft NW swell, but it’s cross-onshore and choppy, so that’s a no-go for clean waves. That holds through the weekend – Saturday the 29th is a big, messy 8 ft onshore mess, with strong wind. Only for the hardcore, and even then, it’s more of a kite session with the wind and beach setup.
The following week, from Monday the 31st into early September, has some surfable but very ordinary conditions. Nothing stands out until Wednesday the 2nd of September, where we get a 5 ft WNW swell, but it’s cross-shore with light wind. The 3rd of September has a huge 8 ft W swell with strong energy (1037) and clean offshore wind in the morning, but that’s over 8 ft, so only for experts. The 4th is similar, but the 5th and 6th are back to poor conditions with storms and strong winds.
So, the one true standout is Monday morning, 24th August – clean, 4 ft NW groundswell, offshore wind, and moderate energy. Get it while it’s good.
