Conditions at Stockton in July
July: Midsummer Onshore Grind
July is the absolute low point. The average swell height stays at 1.3ft (0.4m) with a period of 6.9s. The swell distribution is lopsided: SSE (32.8%), S (21.3%) and SE (19.2%) dominate, but the majority of that directional energy is under 1.6ft (0.5m), making it micro and messy. Wind is overwhelmingly from the onshore quadrant, with SSW (14.0%), S (11.2%), SW (11.1%) and SSE (9.3%) combining for close to 46% of observations. Just 2% of the time are the winds ideal for surfing. Water temperature hits 25.1°C and the air averages a warm 24.4°C, so it feels like summer, but a south-facing beach under a persistent southwest flow is basically a washing machine. Grab a longboard and enjoy a knee-to-waist high summer session if you can.
