Weather Fusion user guide

Weather Fusion helps you monitor your personal weather station data on iPhone, iPad, and Mac. Use it to check current conditions, explore historical trends, and inspect detailed observations when you need exact values.

The first time you open Weather Fusion, the app offers to guide you through setting up a provider so you can connect your station data right away.

Weather Fusion reads station data from your provider account. Your station must upload to the provider over the internet. Supported providers include WeatherLink, WiFiLogger, Weather Underground, and Windy.
