Spring starts in March, so it’s often the month when Atlantans start planting a garden — or at least thinking about it ― and hosting and attending more outdoor events. Weather has a significant impact on these activities since you don’t want your newly planted garden to suffer frost damage or your outdoor party or favorite festival to be rained out.
Forecasts for Atlanta temperatures, rain and other conditions are available a month in advance, and they can be a helpful tool when you’re planning your activities. Keep in mind, though, that the further out a forecast is, the less accurate it’s likely to be due to the Earth’s ever-changing atmosphere.
Here’s what you need to know about the March weather forecast for Atlanta.
Significant dates
Last spring frost: March 29, as predicted by The Old Farmer’s Almanac.
Frost dates are important if you’re planting a garden since it reflects the average date of the last light freeze in spring. A light freeze is defined as 29-32 F, and these temperatures can kill tender plants. That’s why gardeners often wait until after the last spring frost to plant. Keep in mind, though, that this date is an estimate with a 30% probability of the last spring frost occurring after this date.
