What changed
Looking at the broader picture, the April–June 2026 period in Vermont recorded an average temperature of 11.65°C, an anomaly of +1°C, ranking 18th warmest for this three-month span. Precipitation for the same period was 124.46 mm, an anomaly of +29.4 mm, ranking 13th wettest. This aligns with a national trend, as global land temperatures for April–June 2026 ranked as the 2nd warmest on record, with an anomaly of +1°C. Vermont's 1-month anomaly for June was 0.24°C cooler than the average for the NOAA Northeast US climate region.
What’s driving change?
The current climate pattern is significantly influenced by a weak El Niño, with the NOAA ONI 3-month anomaly for April–June 2026 at +0.98°C. This El Niño is forecast to persist and strengthen through the end of the year. El Niño typically brings warmer, milder winters to the Northeast USA, though its summer impacts on Vermont are often more muted and can lead to variable rainfall. Vermont experienced an unusual concentration of extreme weather events in the past month, with four wildfires and one flood event, representing 100% of the annual total for both categories. Notably, flash flooding occurred in mid-June in areas like Hardwick and Wolcott, washing out roads, and a flood warning was issued for the Missisquoi River near North Troy later in the month. You can track these and other events at Extreme Weather tracker.
Looking ahead
The ongoing El Niño is expected to continue, with NOAA's Climate Prediction Center forecasting a 40% to 50% chance of above-normal temperatures for Vermont this summer.

Shifting Seasons
Warm / cold seasonsKöppen Dfb · ContinentalHow spring and autumn have shifted in Vermont. Spring is defined as the date monthly temperatures first rise above the long-term annual mean (5.3°C, from 1950–1979); autumn is the date they fall back below it. Temperature swings 28.1°C peak-to-peak across the year - a classic four-seasons rhythm.
