Statistics & Percentiles
Automated Weather Tools for Analysis and Operational Insights
The Statistics & Percentiles service is designed to enhance your data analysis capabilities by providing on-demand statistical insights for any weather station within our network. This service offers:
Daily and Monthly Statistics
Retrieve maximum, minimum, and mean values for a wide array of variables, allowing for efficient assessment of weather trends over custom time periods.
Percentile Distributions
Access percentile distributions for air temperature, wind speed, and wind gust variables. This feature enables you to determine whether current conditions are typical or extreme compared to historical data.
How Users are Implementing the Statistics & Percentiles Service
Utility customers use wind gust percentiles to provide valuable context in support of fire weather monitoring. Station historical wind gust percentile distributions provide critical, site-specific thresholds against which real time gust conditions are compared (see image). Conditions approaching and exceeding these thresholds signify extreme fire risk, and trigger actions to safeguard infrastructure and communities.
Example of wind gust values for select networks in Utah on July 21, 2025 and the gust severity relative to each station’s percentile distribution. Marker values are reported wind gusts in miles per hour. Percentile values of the wind gust reports are reflected in the marker color. All gust values fall below the stations’ 90th percentile, with the exception of a single station reporting 26 mph.

Users can leverage Synoptic’s Statistics service to provide important context to current conditions, or quickly summarize conditions over long periods of a station archive. Compare current conditions against yesterday’s extremes for quick assessment of weather trends, or understand how conditions compare to past extreme events with known impacts to assist in risk planning (see image).
