How to read the month check
The numbers are climate normals: 30-year averages from 1991 to 2020 that NOAA’s National Centers for Environmental Information publish for the weather station at Dallas-Fort Worth International Airport. A single year can be much hotter, colder or wetter.
Each month gets a kind. A hot month averages at least 10 days at 90°F or more, which in Dallas means June, July, August and September. A cool month has an average high under 65°F: December, January and February. The rest are mild. The kind only decides which guides the check suggests first.
May and October are the wettest months at DFW, with more than 4 inches of rain each on average, so it is worth keeping an indoor plan ready. Dallas on a Rainy Day: Museums and Indoor Places Worth the Trip has one.
For heat, the hours matter as much as the month: in summer, plan trails and the Farmers Market for the morning and museums for the afternoon. Trails and shade are in Dallas Parks and Trails: The Best Walks, Rides and Nature Paths in the City.
