The Lowdown
Alright, Rusty here. Let's talk about what's cookin' down at Indian River (Southside). Lookin' at the full 16-day window, I gotta be straight with you—it's a tough stretch. We've got a long, quiet run ahead, and honestly, there's not a single day that screams "drop everything and go." The pattern is mostly small, weak, and wind-affected, with a few brief moments where it's just barely surfable.
The water's sitting at 77°F with a 3°F anomaly, so it's a touch warmer than normal for this time of year—nice for a long wait between sets.
We kick off Monday, July 20th, with tiny 1ft SE swell, but a cross-onshore wind has it all chopped up—poor surf conditions. Tuesday the 21st shows a slight bump to 4ft SSE swell in the morning, and with a cross-offshore wind, it cleans up nicely. The energy is weak at 67, period is a short 5 seconds, so it's weak and crumbly. The afternoon brings a risk of storms and bumpy 5ft southerly swell, but wind shifts and it gets messy.
Wednesday the 22nd is the closest we get to a highlight. We've got a 5ft S swell with an 8-second period, and cross-offshore wind keeping things clean. Wave energy is moderate at 277. Still, it's labelled as marginal due to questionable tide conditions. For an advanced spot like this, if you're keen, the morning window on Wednesday the 22nd is your best bet. But don't expect much.
After that, from Thursday the 23rd right through to early August, it's a grim run of tiny 1ft to 3ft swells with mostly onshore or cross-onshore winds. There's a brief moment on Tuesday, July 28th, with a 2ft SSE swell and light offshore wind from the W, conditions are clean but the energy is tiny at 55. Same again on Sunday, August 2nd, with a cleaner 4ft S swell in the morning, but it's weak.
Bottom line: there's no real standout session here. The best you'll get is a few average, knee-to-waist high waves on Wednesday the 22nd morning. For the rest, expect small, weak, wind-affected surf. It tends to turn around quickly around here, but this run is looking pretty barren.
Rusty.
