Green Mountain State Receives 20 Inches This Summer - It's the most since 1948

The weather service tracks data using the “meteorological summer,” which runs from June to August. 
  • Lahiff said the weather service would not officially declare a record until about a week after the end of August.
  • He said the state has been stuck in the same weather pattern that has caused record-breaking heat waves in many regions to the west.

Central Vermont has received more than 20 inches of rain this summer. It’s the most in 75 years.

The Barre-Montpelier area received 22.7 inches of rain from June to August, the highest it’s reported since at least 1948.

Central Vermont is on track to hit a new record for summer rainfall.

Rainfall totals by year from June-August at the Barre/Montpelier Airport:

Central Vermont has received upward of 20 inches of rain from June to August, putting it on track to have the rainiest summer since the National Weather Service began collecting data in the region.
The Edward F. Knapp Airport in Berlin reported 22.7 inches of rain from June 1 to Aug. 30, according to the weather service. 
Barre/Montpelier reported far more rainfall this year than the 30-year average, partly due to the July storm that dumped 5 to 6 inches of rain on the area.

Culmulative rainfall by day at the Barre-Montpelier Airport:

“June was a fairly typical summer as far as precipitation goes, but July was what kicked us well over normal in most places,” said Conor Lahiff, a meteorologist for the weather service. “And then that pattern has continued into August as well.”
  • Other regions of the state have received even more rain than the Barre-Montpelier area: Worcester, Plainfield, Woodstock and Peru each reported at least 26 inches of rain so far this summer. 
  • It’s difficult to say whether the towns also broke records due to inconsistent or missing data for certain years.
Vermont summer rainfall totals ranged from about 15 inches in Burlington to over 26 inches in certain locations.

Looking ahead, Lahiff said the weather service was reporting signs that the pattern might finally break and bring drier, warmer weather to Vermont. 
  • Little rain is on the forecast over the weekend, and temperatures are expected to reach the upper 80s on Labor Day.
The forecast will also bookend a “nonstop” summer for meteorologists like Lahiff. “Even when we have had a break, it’s been like one or two days, but then we’re already forecasting the next storm in our seven-day forecast,” he said.
