Conditions at Ditch Plains in July
July: Peak Summer Smallness and South Swells
July is the classic Ditch Plains summer month: warm water, small waves and lots of onshore wind. The average swell height stays at 2.6ft (0.8m) and the period at 6.5s. The wave rose is even more south-heavy than June, with S (36.7%), SSE (22.4%) and SSW (17.5%) leading; this is perfect for the SSE-facing beach, but over 70% of all wave energy falls below 3.3ft (1m). Wind remains the biggest obstacle. SW (20.7%) and SSW (17.1%) dominate, putting the beach under continuous sideshore-onshore breezes, and although the ideal offshore percentage rises to 15%, those windows are mostly in the early morning. Water temperature peaks at 21.1°C, air averages 21.7°C and precipitation is 2.75mm/day. When the summer high pressure sets up and a distant Atlantic tropical wave sends 3.5-5ft (1-1.5m) SSE swell into Montauk, Ditch Plains can be surprisingly fun, but the default summer menu is small and soft.
