With an an overall average high temperature of 78° and an average low of 61°, you'll find St. Augustine's summer temperatures a bit more comfortable and winter temperatures a bit chiller than what you might experience in Orlando at the same time of year.

Of course, Florida's weather is unpredictable, so you'll sometimes experience extremes. As an example, the highest recorded temperature in St. Augustine was a hot 103° in 1986 and the lowest recorded temperature was a very cold 10° in 1985.

On average St. Augustine's warmest month is July and January is the average coolest month. The maximum average rainfall usually falls in September. It is during these months that you'll want to pay careful attention to packing for your St. Augustine vacation. Leave the shorts behind in the winter in favor of longer pants and bring a jacket. Even packing a sweater is a good idea in the summer if you plan on a moonlight cruise or carriage ride.

Hurricane Matthew brushed the East Coast of Florida in early October, 2016. The late-in-the-season storm caused major flooding in St. Augustine, proving the importance of knowing how to prepare if you're traveling during hurricane season, which runs from June 1 through November 30. Those that had booked with hotels offering hurricane guarantees or took out travel insurance fared better than those who did not.
