Hi EthansMom (and Molly's too),
I'm not sure if you mean the beginning or end of April. The average highs in early April are around 80 with lows in the upper 50s, but by the end of the month it averages mid-80s during the day and low 60s in the morning.
Last year the first week of April was cool, with highs one day stuck in the 60s and then only getting into the mid 70s for a few days afer that.
Normal rain for April in Orlando is less than 2.5 inches, so it's a relatively dry month.
