Conditions at Belmar in July
July: Midsummer Lull
July is the absolute low point in Belmar's annual swell calendar. Average height sinks to 2.5ft (0.8m) and the average period is 7.0s. The swell spectrum is overwhelmingly dominated by SSE (33%) and S (27%), with the favorable SE quadrant taking a smaller 20% slice - and most of that occurs at knee-to-waist height in the 2-3ft (0.5-1m) range. Rather than onshore winds being the main issue, there is simply a lack of generating storm energy in the Atlantic. Ideal wind jumps to 50% over the summer, which is nice for clean small waves, but it does not fix the size problem. Water temps peak around 21.1°C and air temps average 23.3°C, so summer is best saved for swimming and the occasional soft-top summer session.
