Weather Hazards to Watch For
March in Virginia can turn on a dime, so you get a mix of winter’s last bite and spring’s early warmth. Sudden storms, late frosts, and sharp temperature swings can mess with outdoor plans or travel.
Likelihood of Hail and Severe Storms
Thunderstorms pick up in mid to late March, and some bring hail. Big hail is rare this early, but pea-sized hail happens in stronger storms. These storms can dump heavy rain that quickly cuts visibility for drivers.

Frost and Freeze Risks
Cold nights still happen in Virginia around March 17. Morning lows can drop into the upper 20s or low 30s, especially in rural spots and valleys. That means frost or even a light freeze is possible.

Wind and Sudden Temperature Changes

Planning Outdoor Activities and Events

Events like Shamrock the Block in Richmond or the Church Hill Irish Festival fill the streets with crowds. In mid-March, highs usually hit the upper 50s to mid-60s °F, but mornings can feel chilly in the 40s.
Rain showers are pretty common, and some years bring breezy days that make it feel colder. A light jacket or umbrella really helps. If you’re at a parade, expect uneven ground and maybe wet sidewalks, so sturdy shoes are a good call.
Wind gusts can mess with parade floats, tents, and vendor setups. Organizers keep a close eye on the weather forecast to decide if they need to change plans. As an attendee, check the forecast the night before and again in the morning.

- Comfortable walking shoes for long routes
- Sunscreen if it’s sunny
Crowds usually show up early, so you might be outside for hours. A small backpack with snacks and water helps a lot, especially at family-friendly events. If you’re bringing kids, toss in an extra layer or blanket since they get cold fast.
Best Practices for Event Organizers
If you’re organizing a St. Patrick’s Day event, weather preparation needs to be on your list. Set up a contingency plan for rain—tents, covered vendor areas, or backup indoor spaces.
Work with local officials to watch wind speeds, especially if you’ve got inflatables, stages, or big tents. Keep attendees in the loop through social media or your event website if the forecast looks iffy.
Give visitors practical tips before the event. A quick list of what to wear, parking info, and weather updates can cut down on confusion. Planning for Virginia’s unpredictable March weather helps everyone have a safer, better time.
