2025 Weather in Review

Observations Supporting Action

Synoptic’s 2025 Weather in Review annual report brings together notable weather and environmental observations from across our platform, highlighting how real-time data and historical context help users understand extreme and fast-changing conditions. Built using the Synoptic Weather API and observations provided by hundreds of participating networks, the report illustrates what’s possible when diverse data sources are unified into a single, reliable view.

This report is not an official climatological summary, but a collection of notable observations and patterns observed during 2025 using the Synoptic platform.
