Seasonal Notes
Winter (December–February)
Cooler temperatures and lighter crowds make winter ideal for exploring more remote keys such as Egmont. Water levels may be slightly higher, and cold fronts can temporarily affect conditions.
Spring (March–May)
One of the most popular boating seasons. Low tides expose sandbars more consistently, and weather conditions are generally stable. Expect increased boat traffic, especially on weekends.
Summer (June–August)
Warm water and calm seas are common, making summer ideal for swimming and sandbar visits. Afternoon thunderstorms are frequent, so early departures and weather monitoring are recommended.
Fall (September–November)
Boat traffic decreases, but hurricane season can affect water clarity, channel depth, and sandbar formation. Always check local conditions and navigational updates before heading out.
Navigation & Safety Tips
- Check tide charts before departing, especially when visiting sandbars
- Use updated charts or GPS systems with depth data
- Navigate slowly in shallow areas to avoid grounding
- Anchor responsibly and avoid seagrass beds
- Observe posted rules at preserves and wildlife areas
