Spring brings mid-60s to mid-70s°F highs, calm bay conditions, and peak coastal bird migration. Ideal for kayaking and quiet beach walks. Fall offers similar comfort with lower humidity and fewer insects. Summer turns hot and buggy; mosquitos and no-see-ums thrive in the warm months, so pack repellent. Hurricane season runs June through November. The park has suffered storm damage in the past (including from Hurricane Michael), and closures or limited facilities can follow major weather events. Check current park status before booking during those months.
Peak season with warm weather, perfect for water activities. Book early.
