San Jose Bike Party usually rides regardless of weather . The ride of November 16 , 2018 was the first and so far only time a ride was cancelled . The reason for the cancellation was unhealthy air quality . The entire Bay Area was affected by wind-blown smoke from the Camp Fire far to the north in Butte County . For 2 days including the day of the monthly ride , the Air quality index in the Bay Area exceeded 200 , a level indicating " very unhealthy " air
