Updates in hr min s Forecast update imminent
Alright, this is Rusty checkin' in from Riyue Bay. Let's break down what we've got over the next couple of weeks.
Right off the bat, we have to be straight with you: the first few days are a write-off. Monday the 6th through Wednesday the 8th are a total mess with storm risks and messy cross-shore winds, kicking up chop and making for poor conditions. The swell is weak and short-period, and honestly, it’s not worth paddling out for.
Things start to get interesting on Thursday the 9th of July. A super long-period groundswell (19 seconds) starts to show up, with the combined energy already at 304 (moderate) in the morning and jumping to 562 (strong) by the afternoon. The waves are small, only 2 ft to 2 ft, so it’s marginal, but the clean conditions in the afternoon are a big plus. This long-period energy is building for something special.
Now, the standout – and I mean the absolute highlight – is Friday the 10th through Saturday the 11th of July. This is the one. Friday morning you’ve got glassy conditions with a 3 ft ESE swell, 17-second period, and a combined energy reading of 785 (strong). Friday afternoon just gets better: 4 ft waves, still clean, and the energy jumps to 1347 (very strong). Saturday keeps the dream alive with 5 ft ESE swell, 16 seconds, and energy readings over 1390. This is excellent, powerful groundswell. For a beginner-friendly point break like Riyue Bay (Riyuewan), the long period means the waves will stand up nicely and offer some long, peeling rides. The optimum direction is NE, and this ESE swell is a close match and should wrap in nicely. The water temperature is about average for this time of year, so a spring suit should do you fine. Keep an eye on the crowds though – with quality like this, it’ll be busy, “sometimes” being the word.
After that killer weekend, the energy drops off. Sunday the 12th through Monday the 13th sees the swell shifting to a shorter-period S swell with moderate energy (between 263 and 429). The wind stays cross-offshore making it clean, but the waves are just average. Tuesday the 14th brings a slight bump in size to 5 ft with combined energy hitting 388 (moderate), and it stays clean – a solid “good surf conditions” day, but nothing like the weekend.
From Wednesday the 15th onward into the third week, things get ordinary again. We see a mix of surfable but unremarkable waves, often with cross-shore winds or very light conditions. There’s a brief uptick on Thursday the 16th afternoon with 5 ft SSW swell and clean conditions (energy 347), but it’s short-lived. The rest of the run through Sunday the 21st is mostly small, weak, and lacking any real drive.
To sum it up: suffer through the first few days, then get amped for Friday 10th and Saturday 11th of July – that’s the real deal. After that, it’s a slow fade into average, half-hearted waves. Forecasts can change, and it won’t stay flat forever, but for now, that weekend is your golden window.
Rusty.
