Dallas, Texas Weather in March

March weather

March feels like spring in Dallas, but the weather can change from mild afternoons to cool evenings. Highs average 21°C and lows 8°C, so walking around Klyde Warren Park or exploring the Arts District can be comfortable. Rain falls on about eight days, and showers can interrupt outdoor plans.

The Dallas Arboretum's Dallas Blooms display is a good fit for spring, but wet paths can slow a visit. Keep indoor stops such as the Perot Museum of Nature and Science in mind for rainy spells. April is warmer and a little wetter, so March is a pleasant choice if you'd rather avoid stronger heat.

Events and crowds

The St. Patrick's Day Parade on Greenville Avenue brings crowds to the area, with road closures and busy restaurants. Dallas Blooms also draws visitors to the Arboretum through spring. Dates and details can vary each year, so check the event schedule before choosing a day.

March is a popular time to visit, especially around spring break and parade weekend. It's generally less busy than peak summer, but don't expect quiet streets near major events. Hotel rates can rise when demand is high, while other March dates may feel easier on your budget than summer.

A local tip

Families who want flowers and outdoor time may enjoy the Dallas Arboretum, but weekday visits are often calmer than event weekends. Greenville Avenue is a lively place to watch the parade, though you'll need to allow extra time for road closures and crowds.

For a practical Dallas stop, take the DART light rail to Cityplace/Uptown, then use the free McKinney Avenue Trolley to reach Uptown and the Arts District. It saves you from hunting for parking near busy spots. After a rainy walk, warm up with a bowl of chili at a local diner.
