The Lowdown
Right, look, I’ve been staring at the charts for Nera Rivermouth, and I’ve got to be straight with you – it’s a rough stretch ahead. The next 16 days are looking like a write-off for any decent waves. The swell is small and weak, the wind is mostly cross or cross-shore, and the setup just isn’t there for a proper session.
The first week is a total bust. From Monday, July 27th, right through to the end of the month, we’ve got a mix of cross-shore winds and tiny, messy energy. On Thursday, July 30th, there’s a brief moment of glassy conditions, but the swell is only 1 ft from the SSW with a long period of 16 seconds. The combined energy is weak (102), so it’s just not enough to get excited about. The water is sitting at 73°, which is about average for this time of year.
Friday, July 31st, is the closest we come to anything. The morning goes glassy with a 3 ft SSW swell (period 14 seconds, energy 236), but the wave comment says “surfable waves but very ordinary conditions.” It’s not a stand-out, just the least bad option. The rest of the weekend is a washout with fresh cross-shore winds and lumpy chop.
The second week is more of the same. There’s a gap of several days with no real recommendations. We see some clean conditions on the 3rd, 4th, and 5th of August, but the swell is tiny – 0.7 ft to 2 ft – and the energy is low, with values like 51 and 71. It’s just not worth paddling out for. On Saturday, August 8th, the morning goes glassy with a 4 ft SSW swell, but the energy is still moderate (327) and the period is short (11 seconds), so the waves will be weak and mushy.
Honestly, this is a tough one. Nera Rivermouth is an inconsistent, sheltered river-and-beach break that needs a SW swell and some offshore wind to work. We’re getting the swell direction, but the size and wind are all wrong. If you’re desperate for a paddle, the morning of Friday, July 31st, or Saturday, August 8th, are your best bets, but don’t expect much. For the rest of the time, the setup looks more interesting for kite surfing than paddle surfing with that cross-shore wind.
