The numeric label and circle colour indicate the current temperature. The direction arrow indicates the wind direction.
A longer barb on the direction arrow indicates a wind speed of 10km/h and a shorter barb indicates 5km/h. So, the example above would indicate about 15 km/h.
A flag indicates 50km/h.
