August: Hurricane Season Heats Up
August is still low season on average, but the tropics start to raise the ceiling. The average height ticks up to 0.5m (1.6ft) and the period to 8.2s, while the wave rose shows ESE at 42.6% and E at 28.7%, with ENE at 12.3% and NE at 4.5%. Most of that remains small, but the distribution gets slightly better than July, especially when a named storm spins up in the Atlantic. Wind conditions are less favorable, with SW (10.2%), SSW (9.5%), WSW (8.4%), and E (9.5%) sharing the pie; ideal wind days are only 8%. The real wildcard is hurricane season: a storm moving up the eastern seaboard can send 10-14s ENE swell into Flagler even with local winds from the west. Water temp peaks at 28.1°C (83°F), and average precipitation is 6.05mm/day. Keep your eyes on the tropics - August is when the season can go from flat to firing overnight.
