As with so much else in hang gliding, “that depends.” Pilots who expect to gain altitude need to know how the temperature of the air changes with elevation (typically a drop of 4°F for each 1000′ gained, but that can vary). It’s not unusual to see pilots at a thermal site in the summer dressing for winter temperatures, even though it’s brutally hot on launch.
