Regardless of the time of year, you'll definitely need comfortable shoes for exploring Metairie. It's also recommended to carry a small backpack for water, a raincoat, and other essentials. Although windy weather is not a dominant characteristic of the climate, a light windbreaker can be useful on cool or rainy days, especially in the winter months and transitional seasons.
