Temperatures across nearby coastal zones range from an average high of 65(°)F to an overnight low of 52(°)F, while inland areas reach up to 78(°)F. Northwest winds are currently blowing at 10 to 20 knots, creating choppy local wind waves alongside moderate overall marine energy.

Nearby offshore buoys indicate a primary northwest swell running at 8 feet with a 10-second period, complemented by a lighter southern swell at 2 feet with a 12-second period. Total significant wave heights range between 6 and 9 feet across the outer waters, requiring caution for small craft operators near the harbor entrances.
