Unusual for us in the No. Sacramento Valley in CA but for the last two mornings
it has been 58° and 59° going up to low 90's by mid-afternoon.  We are loving it.  Being inland, we get very hot summers.  We had a heat wave two weeks ago, up to 112° for a few days.  Very warm nights, then down to low triple digits, 101 - 104. We usually don't cool down until Halloween week.  But, we have a long growing season and I usually have fresh tomatoes from June until Oct. Not bad!
