The Lowdown
Alright, let me tell you how it’s lookin’. The next week and a half is pretty grim for Indian River (Southside). There’s a real dry spell here – nothing worth paddlin’ out for from now through the 25th of September. That’s a solid 12-day stretch with no real surf to get excited about. Just poor conditions, small mush, and messy winds.
Things finally start to show a pulse on Saturday the 26th of September. The morning kicks off with a clean little 1.0 ft swell from the ESE. The combined energy is moderate at 185, so there’s some push but nothing crazy. Winds are cross-off from the WNW at 9 mph, so the surface should be tidy. It’s not gonna blow your mind, but after that long flat spell, it’ll feel like a gift.
The real standout comes on Sunday the 27th of September. Indian River (Southside) finally gets a taste of somethin’ special. The morning has a clean 3 ft swell from the east with combined energy jumpin’ to 187 – still moderate but feelin’ stronger. What makes this the pick of the whole outlook is the afternoon session. The wind goes totally glassy – flat calm at 0 mph – with the same 3 ft east swell and the energy climbs to 214. Expect good surf conditions. The water temp is much warmer than normal for this time of year at 76°, so you’ll be comfortable out there in boardshorts. Too small for a crowd to worry about, but it’ll be clean and fun.
After that, Monday the 28th sees the swell fade and the wind cranks back onshore from the northeast at 19 mph, messin’ things up again. So if you’re lookin’ for the window to slide, that Sunday arvo is your golden moment.
