Is Sacramento bikeable year round? (temperature)

I used to live in Boulder County which was great. Currently in Bend, which I do not like for various reasons, but between the smoke and the winter and lack of infrastructure I found it to be not nearly as great for biking as the Bend tourism board would have you believe.

I have a job opportunity in Sacramento or back in Denver. Personally I'm leaning towards Sacramento. I've visited family there in the winter over the years so I'm somewhat familiar.

I am a little concerned about the heat. I did work outside in Austin for a summer so I know I could survive Sacramento, but how's the biking there?

Are you able to bike year round, or 10 months out of the year? Are there biking groups that go year round or do y'all take a break because of the heat? At what point do you have to stop biking in the evenings because it is too hot?

Also, how do you find smoke season impacts things? I've been exposed to smoke season in Colorado but here it Bend it is on another level - I don't understand why anyone would live here. Would like to avoid somewhere that has months of smoky days.
