Temperatures can be extremely variated in very short distances depending on where the cold air gets stuck and where it moves away. Just now when I did my evening ride I had to stop after 5 km and put on goggles after the temp went down 10 degrees compared to the start location. I badly regretted not putting on the extra cotton layer. On the other hand some people use an IR thermometer to measure temperature outside which gives the completely wrong temperature. Can be 10-20 degrees lower than air temperature.
