Vaisala Xweather Report Highlights Weather's Impact on EV Range Across US and Europe
Event summary
- Vaisala Xweather released its 2026 EV Range Report, analyzing weather and road conditions affecting EV range in the US and Europe from March 2025 to February 2026.
- Sun Belt states like Arizona, Florida, Texas, and Louisiana offered the most EV-friendly weather, with median weather-adjusted ranges above 270 miles.
- Northern New England and far north states like Maine, Vermont, and North Dakota recorded the lowest annual median ranges, with Maine at just 220 miles.
- The report identified extreme days where weather significantly impacted EV range, such as a 297-mile range day in New Mexico and a 98-mile range day in Rhode Island during a snowstorm.
- In Europe, Mediterranean countries like Cyprus, Malta, Spain, Portugal, and Greece led with the highest weather-adjusted ranges, while colder northern countries saw shorter effective ranges.
The big picture
The Vaisala Xweather 2026 EV Range Report underscores the critical role of weather and road conditions in shaping EV range, highlighting significant regional disparities. This data is crucial for automotive OEMs, Tier 1 suppliers, and navigation providers as they refine range prediction models and design charging strategies. The findings also emphasize the need for real-time, high-resolution weather data to optimize EV performance and infrastructure planning, particularly in regions prone to extreme weather conditions.
What we're watching
- Regional Trends
- Whether the Sun Belt states can maintain their lead in EV-friendly weather conditions and how the Mountain West states will adapt to the observed declines in annual median range.
- Weather Factors
- The pace at which EV makers and infrastructure planners integrate rolling resistance, air drag, and thermal control data into their strategies to optimize range prediction and charging infrastructure.
- Market Impact
- How the insights from the report will influence EV adoption rates and charging infrastructure development in regions with historically lower EV range.
