Secondary research

The convenience of Apple Weather is that you can see the air quality reminder when you open it. It is an important index for outdoor sports people, and the integration of detailed information is very conducive to observation. Among them, the time of sunrise and sunset is particularly important for riding in the mountains. There are no street lights. If you don’t bring lighting equipment, you have to hurry down the mountain before sunset.

Accu Weather is the most commonly used weather software for cyclists. It has Realfeel body temperature, which can better reflect the human body’s feelings of temperature compared to ordinary temperature indicators.

However, this index is only accurate on the day, and the forecast is only rough. Clicking on the details also has specific wind direction information and wind speed, as well as hourly and daily weather forecasts, which are very detailed.
