We help drivers and autonomous vehicles make better decisions for every journey. The Xweather Road Weather API provides comprehensive road condition classifications (dry, wet, slush, snow, and ice), road surface temperature, and water, snow, and ice thickness. With robust documentation and SDKs, integrating road weather data and visuals into your applications has never been easier.
Wet conditions account for nearly three-quarters of all weather-related road accidents. Even a small amount of water on the road reduces grip, and the risk of aquaplaning increases rapidly with heavy rainfall.

Water film thickness
Snow is a common winter road hazard causing 17% of weather-related accidents in northern parts of Europe and North America. Unlike water, snow can be present on the road for long periods.
Identify snow and slush road conditions
Ice typically forms on roads when low temperatures turn morning dew into frost or freeze standing water on the pavement. Although ice is less common on roads than water and snow, it is far more dangerous for drivers.

Road weather forecasts for the most demanding use cases.
Infotainment and driver support
Road weather is the key to driver safety with timely hazard warnings and enhances other vehicle systems such as navigation and EV range calculation.
ADAS and AD
Road weather is invaluable in advanced driver assistance (ADAS) and autonomous driving (AD) systems. It provides crucial data on the current and upcoming road surface state to keep drivers informed and in control.
Reliable real-time weather data is vital in optimizing systems performance to manage the impact of changing environmental conditions on vehicles.
Timely, relevant road weather data helps fleet operators keep drivers and vehicles safe and informed while maintaining operational efficiency.
Delivery and logistics
Take your route planning and timing to the next level with weather-aware navigation and protect drivers with predictive warnings of upcoming road weather hazards.
Research and simulation
Our comprehensive, real-world data supports the development of advanced driving technology and customer-facing road weather products.
Automotive + Transportation
The Road Weather API is powered by advanced modeling through a proprietary network of road weather sensors, high-quality data sources, and algorithms that predict how environmental conditions and other factors will impact the pavement. Precipitation, solar radiation, traffic, maintenance activities, and the physical attributes of the road all play a significant role.
Our Road Weather API combines these inputs with machine learning to produce an accurate nowcast for the road ahead.

// Data you can trust
Accurate, reliable road weather information makes journeys safer and more comfortable for drivers and passengers. We continuously improve our forecasts by validating our data against ground truth measurements from road weather stations and mobile sensors.
Our solutions are the product of 85+ years of sensor development experience and more than 20 years of road weather forecasting. We work with top-tier vehicle manufacturers and automotive tech companies worldwide to improve driver safety, comfort, and convenience.
The Road Weather API covers millions of kilometers of road in North America, Europe, and Japan. We model primary and secondary roads separately to reflect the effects of different road surfaces, traffic levels, and maintenance priorities. Bridges are also modeled separately to account for the free flow of air beneath the road surface.
