April is a smart time to fly from Hartsfield–Jackson Atlanta International Airport (ATL) to Cyril E. King Airport (STT): it falls after the high winter season yet before the summer hurricane window, offering pleasant weather and moderate prices.

For lower crowds, consider traveling in early April or midweek — these windows often provide the best mix of value and weather.
