August: Waiting on the Tropics
August remains flat in the statistics, with the average swell height still 0.4m (1.3ft), but the average period ticks up slightly to 6.8s-a small hint that tropical pulses can lift the swell window. The distribution is still dominated by ESE (40.2%) and E (23.3%), with ENE (13.3%) starting to contribute a few more 0.5-1m (1.5-3ft) lines. Ideal wind is only 3% of the time, and the wind rose continues to favor SSW/SW/onshore flow. Water temperature peaks at 28.3°C (83°F), air temperatures average 27.7°C (82°F), and precipitation is high at 5.24mm/day. This is the month when the forecast models become your best friend: the climatological averages are small, but a well-timed hurricane in the Bahamas or Gulf Stream can switch Jacksonville Beach from flat to firing in 48 hours.
