The Lowdown

Alright, let’s get stuck into the outlook for Nera Rivermouth.

Overall, the next couple of weeks are a bit of a mixed bag, with some solid pulses of energy coming through, especially after a slow start. This is a sheltered river and beach break, so it takes a specific window of swell and wind to really fire, and we’ve got a couple of those windows in sight.

For the first few days, it’s pretty quiet. Saturday (25 July) through Sunday (26 July) are a write-off with cross-shore wind and tiny, weak swell – the wave energy is barely registering. Honestly, not even worth paddling out for. Monday (27 July) is where things start to get interesting. The morning shows a jump to 6ft swell from the SSW with a clean 12-second period, and the wind gets a bit cross-offshore. The combined energy hits a solid moderate level, so it’s got some push. That Monday morning session is going to be the first one to circle.

The standout window, though, comes in on Tuesday (28 July). Seriously, this is your best bet in the whole run. Tuesday morning sees clean conditions again – it’s cross-offshore, light breeze (5 km/h) – and a nice 5ft SSW swell, 12-second period. Tuesday afternoon follows the same vibe with a 5ft swell, and the wind stays cross-off. It’s not huge, but for Nera Rivermouth, this is perfect shape and size. The water temp sits right around average for the time of year, so no worries there.

Wednesday (29 July) drops back to tiny slop, so patient again.

Now, looking into the second week, there’s a bigger pulse coming but it’s got a cross-shore wind problem. On Monday (3 August) the afternoon sees 6ft SSW swell with very long-period energy (18 seconds), but the cross wind makes it messy. Then Tuesday (4 August) and Wednesday (5 August) up the ante with swell heights around 6ft to 7ft, and the energy is through the roof. That’s some serious power. Short-period stuff mid-week (11 seconds) means it’ll be a bit jumbled though. This is expert territory at that size for Nera, and the wind is cross all the way. It might actually be more interesting for kite surfing than paddle surfing, to be honest. The morning of Thursday (6 August) looks glassy but tiny.

A long-range mention: going into the second weekend (9 August) the wind switches offshore, but the swell is tiny (0.7ft). Clean as a whistle, but not much to ride.

So, if you’re looking to score: Tuesday, 28 July from morning through the afternoon is the pick of the whole 16 days. Clean, 5-5ft, and solid shape. After that, the bigger stuff (3-5 August) has the size but the cross wind is a letdown. Keep an eye on the morning of Tuesday 4 August – that’s when the energy peaks, but you’ll need to gamble on the wind.
