Conditions at Maria's in September
September: The Hurricane Window Opens
September is a wild card. Average wave height is 3.6ft (1.1m), and the average period jumps back to 9.1 seconds, signaling a return of longer-period energy. NE (34.2%) and ENE (33.6%) still dominate, but tropical storms and hurricanes in the Atlantic-Caribbean basin can throw true SW, WSW, and W swell at Maria's -- the directions this spot is built for. Because of that, September has some of the biggest upside of the year despite the modest average stats. Wind is ideal 81% of the time, led by ENE (25.0%) and E (20.8%). Air temperature is 28.5°C, water temperature is the warmest of the year at 29.3°C, and precipitation jumps to 4.91mm/day. If a hurricane passes through the right corridor, Maria's can turn on.
