Table - best surf conditions forecast for Sebastian Inlet-Third Peak over the next 16 days.
Alright, let’s break it down for Sebastian Inlet-Third Peak (beach/jetty). This spot likes swell from the NE, but we’re lookin’ at a real flat spell over the next 16 days. Wave energy numbers are all low – between 5 and 72 – so it’s weak stuff. Water temp is 84°, right around average for summer here.
Saturday the 11th: partly cloudy, cross-shore SE wind at 12 mph. Swell’s a measly 1ft from the east, 8 second period, energy 16 – nothin’ doin’.
Sunday the 12th morning is the first little chance: light offshore SW wind at 9 mph, clean, but only 1ft east swell, period 8 seconds, energy 13. Tiny. Afternoon picks up a bit – 2ft from the SE, 8 seconds, energy 36, cross-off SE wind at 9 mph – still poor.
Monday the 13th: morning glassy offshore from the SSW at 6 mph, 1ft east swell, energy 19.
Tuesday the 14th morning is dead glass – SE wind at 3 mph, 1ft east swell, period 8 seconds, energy 17. That’s your cleanest knee-high moment. Afternoon turns choppy with ESE cross-on at 12 mph.
Wednesday the 15th: another glassy start, SE at 3 mph, 1ft NE swell, period 7 seconds, energy 22 – still weak.
Thursday the 16th: light offshore SW at 6 mph, 1ft NE swell, period 7 seconds, energy 16.
The whole middle stretch is tiny – 0.7ft to 1ft – short period, mostly clean winds, but no power.
Finally, Wednesday the 22nd afternoon we get a “surfable but ordinary” rating, score 1. That’s 2ft from the east, period 7 seconds, energy 40, cross-off WNW wind at 6 mph – clean but weak. Thursday the 23rd afternoon similar: 2ft from the ESE, 8 seconds, energy 72, S cross-off at 9 mph – same story.
Last few days into the 26th: 1–2ft swell, short period (4–8 seconds), mixed winds. Combined energy never gets out of the weak range.
Bottom line: no real standouts. The glassy mornings might give you a clean 1ft wave if you’re desperate. Beginners could mess around in the 1–2ft stuff. Otherwise, those SE cross-shore afternoons with 15–18 mph winds and tiny waves look better for kite surfing than paddlin’.
