Conditions at Sebastian Inlet in July
July: Trade Wind Chop
July keeps the summer lid on. Swell averages around 1.5-2ft (0.5m), period is 8.0s, and ideal wind remains at 13%. The wave rose is now dominated by ESE (44.7%) and E (36.6%) windswell, with almost all observations in the 2-3ft (0.5-1m) range and smaller. The wind rose is dominated by SE/SSE/S/SSW/SW flow - ESE (13.7%), SE (12.6%), SSE (10.2%), SSW (10.1%) - all onshore or mostly cross-shore and rarely helpful for a clean face. The result is usually a lumpy, texture-filled lineup with knee- to waist-high waves. Unless a tropical system angles in from the Atlantic, July is not the month to book a surf trip.
Air temps peak around 27.4°C, water is a warm 28.5°C, and rainfall remains high at 5.82 mm/day. It is humid, sticky and mostly flat; low expectations are the key to enjoying it.
