BigWeather / User Guide

Welcome to the BigWeather user guide

Thank you for using BigWeather.

Please note that I don't get paid to develop this software, I wrote it for myself but decided to share with the Garmin community free of charge.

I'm a dedicated runner, passionate about my health/fitness and been an owner of many Garmin devices over the years (305, 310, 910, vivofit to name a few).


Please ensure that you are using the following :

  • 6.10 firmware AND latest GPS on the 920XT!
  • 3.30 firmware AND 2.80 GPS on the vivoactive!
  • Garmin Express version or later.

Operation Guide


BigWeather needs the following in order to work :

  • GPS fix
  • Bluetooth connection to the phone
  • Phone has internet connection

How Does BigWeather work?

BigWeather first attempts to get a GPS fix. Once it has a GPS fix, it tries to communicate with the phone, it does this via bluetooth. Once that connection is established a call is made via 3G, 4G, Wifi etc to the interet to get the weather data using the latitude and longitude co-ordinates. Two requests are made, one for the current weather and a second for the forecast weather.

Weather Data

BigWeather uses a free source to get it's weather data -- Open Weather Map

Please do not leave bad ratings if the weather is not correct, please contact Open Weather Map!
