 - Tailwind with riding speed (graphical, 1x1 field): Shows an arrow indicating the current headwind direction next to a label reading your current speed and the speed of the tailwind. If you ride against a headwind of 5 mph, it will show "-5". If you ride in the same direction of a 5 mph wind, it will read "+5". Text and arrow are colored based on the tailwind speed, with red indicating a strong headwind and green indicating a strong tailwind.
 - Wind direction and speed (graphical, 1x1 field): Similar to the tailwind data field, but shows the absolute wind speed and gust speed instead. The "circular" variant uses the same circular graphics as the headwind indicator instead.
 - Wind forecast / Temperature Forecast / Precipitation forecast (graphical, 2x1 field): Line graphs showing the forecasted wind speeds, temperature or precipitation for the next 12 hours if no route is loaded. If a route is loaded, forecasts along the route will be used instead of the current location.
+- Headwind forecast (graphical, 2x1 field): Shows the forecasted headwind speed if a route is loaded.
 - Weather forecast (graphical, 2x1 field): Shows three columns indicating the current weather conditions (sunny, cloudy, ...), wind direction, precipitation and temperature forecasted for the next three hours. Tap on this widget to cycle through the 12 hour forecast. If you have a route loaded, the forecast widget will show the forecasted weather along points of the route, with an estimated traveled distance per hour of 20 km / 12 miles by default. If placed in a 1x1 datafield, only the current weather conditions are shown.
 - Relative grade (numerical): Shows the relative grade. The relative grade is calculated by estimating the force of the headwind, and then calculating the gradient you would need to ride at to experience this resistance if there was no wind. Example: If you are riding on an actual gradient of 2 %, face a headwind of 18 km/h while riding at 29 km/h, the relative grade will be shown as 5.2 % (with 3.2 % added to the actual grade due to the headwind).
 - Relative elevation gain (numerical): Shows the relative elegation gain. The relative elevation gain is calculated using the relative grade and is an estimation of how much climbing would have been equivalent to the headwind you faced during the ride.
