Mid/late June temperatures near Tuolumne

I think I am going to shoot for a backpacking trip to Young Lakes June 18-22. What would the night time temperatures be for that time? I have a 20 degree bag. Will that be sufficient? Thanks.

hard to say, I have been in that area and froze my butt off with 15 degree temps, and the following year we were in the 50's at night. I always go in on that weekend and have been for the last 25 years and can say the only thing that is consistent with the temps, is they are not consistent. I would guess a 20 degree bag would be OK with a good tent to help keep the wind out.
