Weather & vehicles
The data behind safer vehicles
Weather shapes how vehicles and people perceive the road, how far an EV will travel, and how safely an autonomous system can operate. The cost of getting those decisions wrong is measured in accidents, degraded performance, and barriers to scaling next-generation vehicle platforms.
Xweather delivers road conditions and atmospheric data through a flexible API built for automotive use cases. From forecasts that sharpen ADAS and autonomous driving models to range-accurate weather inputs for EVs, Xweather gives carmakers and AV developers the data layer their vehicles need to adapt to changing conditions in real time.
Backed by Vaisala's nearly 90 years of weather innovation, 40 years of road weather sensor design, and over 30 years of developing accurate road weather forecasts with safety professionals, Xweather provides the world's most sophisticated road weather data. Many of the world's largest automotive brands already rely on Xweather to improve safety, efficiency, and comfort for drivers and passengers.
ADAS and autonomous driving
Real-time and predictive road conditions data extends the operational design domain beyond the vehicle's onboard sensor range.
EV range and efficiency
Atmospheric and road conditions parameters for aerodynamic and rolling resistance, and thermal management modeling to improve range prediction accuracy.
Connected car and infotainment
Weather-aware navigation, local hazard warnings, and real-time road conditions data for in-vehicle safety and comfort experiences.

The Xweather EV range report
Discover how weather and road conditions affected EV range across the contiguous US and Europe over a full year, from March 2025 to February 2026. The 2026 report quantifies the contributions of air density, rolling resistance, road surface state, and cabin climate demand separately, providing manufacturers with the parameters they need to build accurate, weather-aware range models.

Impact
From forecast to vehicle system
Xweather road weather data connects weather conditions to in-vehicle decisions. Real-time road conditions intelligence flows from sensor networks and forecasting models into production-grade APIs that automotive systems consume every 15 minutes. Historical data supports validation and scenario generation, real-time feeds enable performance testing, and the same APIs scale to deployment: one integration from R&D to production.
Improve safety performance
)
Preemptive hazard data for friction, ice, water film, and visibility acts as a virtual sensor beyond line of sight, reducing reaction time and unexpected disengagements.
Build driver trust
)
Predictive intelligence reduces sudden braking, system disengagements, and uncomfortable driving behavior caused by undetected surface changes.

Weather-aware driver warnings for Euro NCAP
Driver warnings help automotive innovators achieve a higher Euro NCAP rating by detecting weather-dependent speed limits and displaying warnings for bad weather and slippery roads.
Warn drivers about up ahead weather hazards
Since vehicle sensors cannot detect all upcoming local hazards, using external weather data can help warn drivers. The driver may need to take over the driving task if the vehicle is not permitted to operate in adverse weather conditions.
Display correct speed limit during a weather event
In some countries, there are conditional speed limits related to weather, among other conditions. Xweather data can detect all weather events relevant to conditional speed limits.
Achieve a higher Euro NCAP rating
With Xweather data, carmakers can gain additional points in the Euro NCAP Safe Driving and Assisted Driving protocols.
Use cases
