March in Marathon, Florida

Spring into family fun this March with great options for family spring break escapes or Easter vacations. Due to our minimum guest booking age of 25, Tranquility Bay is not a popular destination for college spring breaks, so families can rest easy knowing that Marathon is a great destination for family spring break vacations with the little ones. Families can discover our spacious two and three-bedroom Florida Keys beach houses, while couples love a romantic retreat in our more intimate Tropical Garden Guestrooms.

Marathon, Florida Weather in March

Although the average high temperature in March is 79° F in Marathon, the island can sometimes be surprised with a late seasonal cold front. But with an average low temperature of 69° F in March, chances are you will be sitting on a warm, sunny beach soaking up the glorious Florida Keys sunshine. Rain during this period is scarce, with the lowest rainfall averages of the year. March is largely a gorgeous month to visit Marathon but also hugely desirable among visitors.

Marathon - What to Wear in March

Our clothing style throughout the year is "Keys Casual" and most restaurants do not require a dress code. Pack your summer gear, including flip flops, a swim suit, shorts and a light shirt, but keep in mind that a late seasonal cold front could sweep through at any time so it's always wise to bring light layers that you can add to your wardrobe when needed. Don't forget a light jacket or blazer and jeans for a night out, in case you experience a chilly evening. Nights can be cooler in March but be prepared for glorious sun shining days! Don't forget the sun screen and a hat for sunny beach days.
