Conditions at Shonan in June
June: Tsuyu Rain, Small South Groundswell and Onshore Textures
June is the heart of the Japanese rainy season, and it shows. Average precipitation jumps to 6.01mm/day, air temperatures reach 20.7C and water warms to 21.4C. The swell mix is overwhelmingly southern -- S (33.6%), SSW (24.3%), SSE (20.5%) and SE (10.8%) -- but the average height is still only 2.3ft (0.7m) at 7.8s. Most waves fall into the 2-3ft (0.5-1m) fun-sized class, with some 3-5ft (1-1.5m) SSW lines when a low pressure system lingers offshore. Onshore wind is the main story: SSW (16.6%), S (14.3%) and SW (10.6%) dominate, and the ideal-wind reading is stuck at 16%. June can be fun between rainbands when a brief N-NNE offshore lines up, but consistency and surface quality are poor.
