The Lowdown
Alright, Rusty here, and I'm calling it like it is: Indian River (Southside) is in a flat spell right now. No real surf to speak of for the next couple of weeks. The water is running about 78°, which is a touch warmer than normal for this time of year, so at least the water's comfortable.
We've got a long gap of several days with nothing happening. Monday the 10th through Friday the 14th, the swell is tiny—barely 1ft to 2ft. The combined energy is weak, mostly in the low double digits (12 to 25), so there's no push. Even when the wind is glassy or offshore, the waves are too small to ride. It's a beach/jetty setup, so it's exposed, but without swell, it's a washout.
Saturday the 15th and Sunday the 16th stay small—still around 1ft, with cross-shore or onshore winds. The energy bumps up a bit to 38 on Saturday morning, but it's still weak. Sunday afternoon sees a gust of 22 mph cross-shore, making it lumpy and messy. Not worth getting wet.
Monday the 17th shows a little bump to 2ft–3ft from the south, with offshore winds in the morning (NNW at 12 mph), and the combined energy hits 42 to 89. That's still weak, and the period is short (6 seconds), so the waves will be weak and crumbly. It's clean, but not really surfable.
Then Tuesday the 18th through Friday the 21st, the swell picks up a bit. The combined energy gets into the low triple digits—100 to 151—which is moderate. But the winds are cross-on or onshore, and the swell is from the southeast or east-southeast, with periods from 10 to 15 seconds. That 15-second period on Tuesday the 18th is a groundswell, but at a beach break, it'll break too straight, and with onshore winds, it's choppy. For the experienced crew, there might be a wave or two, but quality is poor. Water temp is still a touch warmer than normal.
From Saturday the 22nd through Tuesday the 25th, the swell drops back to 1.0ft–2ft, with combined energy below 100. Winds are mostly cross-off or cross, so it's clean, but there's no power. Periods are short (4 to 8 seconds), so it's just weak windswell.
Honestly, there's no standout here. The best you might see is Monday the 17th morning—2ft from the south with offshore winds—if you're really desperate for a paddle. But it's a flat run, typical for this area when there's no consistency. Forecasts can change, but for now, it's a no-go.
Rusty.
