The reason I asked is because as you get toward the end of May, there is much less variance in the weather. At the beginning of the month, it is still possible to see some days stuck in the 70s and mornings in the 50s. But by the time you are going it should be well into the 80s during the day (and possibly higher) most of the time, with morning lows in the 60s to near 70.
Enjoy!
