Fredericksburg is part of Gillespie County, which spans about a thousand square miles. The county is very geographically diverse; as part of Texas Hill Country, some areas reach an elevation of 2000 feet, meaning weather patterns are slightly varied. On the whole, you can expect Fredericksburg to have very warm, sunny summers and colder winters averaging around 50 degrees in the flat areas.

Rain is common in Fredericksburg, and most of the region’s 25 or so annual inches of rain fall in the months of April through June. (Think of it as April showers extended for two months.) Bring a large umbrella and some rain boots. It is almost always warm enough for short sleeves or at most, a light jacket.

In terms of deciding when to visit, Fredericksburg stays lighter longer during the summer, which allows you to pack more activities into your days. Most of Fredericksburg’s attractions and museums are open later in the summer, making this the ideal season to visit. However, there are some events and festivals that occur during the fall, winter and spring, so it really depends on what you’re interested in seeing.
