Key West Scuba Diving in July
Key West scuba diving in July is great. Constant water surface temps of 85°F or more mean no chill even on multiple deep dives and visibility is usually very good. Town is jumping with many special events, and lobster mini-season is the last consecutive Wednesday and Thursday in the month.
July Weather Outlook
July is hot in Key West, around 89°F degrees most of the time, and nearly windless with the lowest average wind speeds of the year at about 9.4mph. There is a chance of thunder showers almost every day, and high humidity means on and in the water is the place to be.
July Marine Life
Big schools of Mangrove Snapper gather on the reef to spawn in July and the wrecks hold a lot of big fish down in the deep, cool waters.
