The Lowdown
Alright folks, Rusty here. Let’s have a look what’s on the table for Buffalo Bay Wildside.
We’ve got a bit of a slow start, but things are shaping up. The first real chance for a paddle comes Tuesday morning, September 15th, with a 5ft easterly swell and a period of 11 seconds. The water temperature is 60°, which is about 4° colder than we’d normally expect this time of year – feels a bit nippy out there, so don’t forget the rubber. The combined energy is moderate (854), but it’s the afternoon that really wakes up. Tuesday afternoon turns glassy with a light easterly offshore breeze at 3 mph, and the swell drops to a clean 4ft from the east. That’s the kind of session where it feels like you’ve got the ocean to yourself – smooth faces, nice lines. That’s the standout for the early part of the week.
Wednesday the 16th gets messy in the morning with a solid 8ft southwest swell, but strong southerly cross-on winds at 16 mph blow it out. Not worth your time. By Wednesday afternoon, things clean up nicely: the wind switches to a light cross-offshore from the ESE, and the swell settles to 5ft from the southwest with a 14-second period. That’s proper groundswell with real heft to it – combined energy of 1673. The guidance says this is excellent for experienced surfers, and I’d agree. That’s your other standout.
Thursday the 17th keeps the southwest swell running at 7ft in the morning and 7ft in the afternoon, both with clean cross-off winds, but the tide and conditions are a bit marginal. Still rideable if you pick your moments. Friday the 18th sees the swell drop to 6ft, but the wind cranks up to 19 mph – clean but bumpy, and the energy is moderate (1438).
Now, the weekend. Friday afternoon through Sunday the 20th, the swell jumps up – 10ft on Friday, 12ft on Saturday morning, and stays solid. That’s big stuff. Combined energy for Saturday morning hits 2817 – strong. These waves are only for expert surfers. Also, the period drops to 8-9 seconds on Friday and Saturday, which is short period, so expect choppy, crumbly faces at this beach. The wind is cross-offshore and clean, but this setup looks more interesting for kite surfing than paddle surfing given the size and short period. It’s a beast.
We hit a bit of a lull from Sunday the 20th afternoon through to Tuesday the 22nd. Swells drop to 5-6ft, but winds are cross or cross-on, and the energy dips. Not great. Wednesday the 23rd is small and messy.
Then, a late highlight: Monday the 28th September morning brings back a 8ft southwest swell with clean cross-off winds at 9 mph and energy at 1258. This one’s for experienced surfers again – solid, clean, and lined up. Tuesday the 29th morning also delivers a 8ft south swell, clean offshore breeze, and strong energy (2553). That’s another expert session with punch.
So overall? The best windows are Tuesday 15th afternoon – glassy and user-friendly, and Wednesday 16th afternoon – powerful groundswell for the crew who know what they’re doing. The big weekend is for experts only, and the long-range looks promising but less certain. Keep an eye on that Monday the 28th and Tuesday the 29th.
Stay salty,
Rusty
