This calculator is accurate within a few tenths of a degree, at speeds above 5mph. Use your own local temp, punch in the speed you'll be riding, and see what it'll actually feel like. This is a great way to decide if you need to bundle up for that ride today! You can also select one of the locations nearest you below, get the temp and info from an area Ham Radio Weather Station, then click 'BACK' to come here and run the calculation.
