The terrain within the city is relatively flat, enabling the bike commuter. And one of Boise's crown jewels, the Greenbelt, is a favorite haunt of recreational cyclists. There is a place in Boise for cyclists of every interest and ability. The temperature rarely gets over 100, even in the dead of summer, and it's rare for the mercury to drop below zero, even on the coldest days. Typically, in winter the temperature rises to above freezing during the day, so snow doesn't stick to the ground very long.
Wind is typically a non-factor for cyclists.
What wind there is comes in predominantly from the west or northwest. It's not unusual to have wind from the southeast in the morning, switching to west in the afternoon. Makes for a nice ride to Star or Middleton, with the wind pushing you over, and then pushing you back in the afternoon. Precipitation is minimal in Boise. We get a few snowstorms in the winter, and some rain showers in the spring and autumn.
