When activities are uploaded into Garmin Connect, the weather information during the activity will appear on the activity's Details page. The weather data is captured at the time when the activity is started.

This information is collected from the closest official weather station to your starting point. For the most part, local airports will be the official weather stations.

In the event that the weather station does not provide all weather data, it is possible for your activity to display a limited amount of weather information. This can include missing information such as sky conditions, wind speed, direction, or temperature.

Why Does the Temperature Graph in My Activity Have a Different Temperature Than the Weather Data For My Activity?

If your Garmin device has a barometric altimeter sensor in it, you will see a temperature graph included in your activity summary data. Your body temperature affects the temperature reading for this sensor. To get the most accurate temperature reading, you should remove the watch from your wrist and wait 20 to 30 minutes. You can also use an optional tempe™ external temperature sensor to view accurate ambient temperature readings while wearing the watch. See the screenshots below for one example of how your body temperature will affect the temperature displayed in this graph.
