The Lowdown
Hey folks, Rusty here, with a look at what's coming up at Nera Rivermouth. It's a bit of a mixed bag, so let's get into it.
First up, we've got a bit of a slow start, but there's a couple of windows that look promising. The standout is a late call, so keep an eye on it.
The first real action we see is on Sunday, 19 July. The morning is looking pretty good with a 3 ft SSW swell, a very long period of 21 seconds, and glassy conditions. This is a proper groundswell, and with that kind of period, it'll be a bit more lined up at the river mouth than a beach break. The combined wave energy is moderate (839). For a beginner spot, this is about as good as it gets – clean, small, and easy.
Monday, 20 July, is also a good one. The morning has a 4 ft SSW swell, still a long period of 18 seconds, and glassy conditions with no wind. The energy is moderate (851). Then the afternoon drops to 3 ft but remains glassy. Two solid, clean sessions.
After that, things get quiet. From Tuesday, 21 July right through to the end of the month, the wind turns onshore and cross-shore, and the swell drops away. There are a few days with no surf at all, and the rest have poor conditions. It's a long stretch of flatness.
Now, the real standout of the whole 16-day window is on Monday, 27 July. The morning session has a 7 ft SSW swell, with a 15-second period and a light cross-offshore breeze. The combined wave energy is strong (1714). This is a bigger, more powerful swell, and with clean conditions, it will be a proper session. The afternoon is a touch smaller at 6 ft, but still very clean. This is the one to circle on the calendar. Keep in mind that at 7 ft, it's getting a bit sizeable for beginners, but for anyone with a bit of experience, it's the pick of the bunch.
The first few days of August bring a new swell, but it's a bit rough. On Saturday, 1 August, we have a 7 ft SSW swell with a 16-second period, but the wind is a gentle cross-onshore, making it choppy. The energy is very strong (over 2200), but the conditions are marginal. It's worth a look if you're keen, but it won't be clean.
So, to sum it up: get out there this Sunday and Monday for some clean, small waves. The big one to aim for is the Monday, 27 July, when the swell and wind line up. After that, it's a bit of a gamble.
Rusty.
