About Key West

The forecast point for Key West represents conditions near Stock Island, while exposed water, beaches, wetlands, courses, or remote access within the coverage area may differ. The day’s key decisions involve Keys marine wind, reef or bay visibility, tides, heat, and Overseas Highway access.

Planning an Outing at Key West

Check Keys marine wind, reef or bay visibility, tides, heat, and Overseas Highway access for the exact access point and activity—not just the nearest city forecast. Confirm current park, refuge, marina, ramp, ferry, road, bridge, course, or operator notices that apply to Key West, and preserve enough daylight and shelter margin to change plans.

Weather Tips for Key West

• Check wind, tides, marine forecasts, beach flags or inlet current, and water-quality notices for the exact access area.
• Leave beaches, boats, piers, jetties, and exposed shorelines immediately when thunder is heard.
• During tropical threats, follow local evacuation, bridge, marina, ferry, campground, and coastal-closure instructions; storm surge may affect access before landfall.
• Check conditions near Stock Island shortly before the activity starts.
