Early in May, you can expect morning low temperatures to be in the low to mid-50s F (10-12 C) with afternoon highs warming into the low to mid-70s F (22-23 C).
A few of the cooler mornings this time of the month can still dip down to 45 F (about 7 C) or lower.
By the end of this month, however, the morning low temperatures will have warmed to the low to mid-60s F (16-17 C) while the afternoons will sport highs in the low 80s F (about 27 C) with a few days reaching the upper 80s F (31 C) or higher.
