How bad is morning traffic?

Hey all! I’m super excited to be visiting for the first time this summer. I’ll be flying in to SFO and spending some time in the city before meeting my brother in Monterey. I’m planning on flying out of SFO, and I’d really like to take CA-1 back up. I’ve heard lots of good things about the views - we don’t have much in the way of coastal scenery in the Midwest - I’m looking forwards to it. I guess my question is - my phone is saying that the drive will take about 2hr 15min right now (9:30pm on a Wednesday). If I want to get to SFO around 10am, how bad will traffic be? I’m from Chicago so I’m not scared or anything - just want to make sure I plan accordingly. TIA!
