What Mesa's weather means for nonprofits
About 176 days a year reach 90°F in Mesa, so the comfortable window for a walk or run is the stretch around December; book the main event then and plan the summer around indoor drives. With December averaging a high of 66°F, a donor gift works better as an embroidered cap or a light quarter-zip than as heavy fleece. Winter nights still drop to an average low of 40°F in December, a long way from the summer heat, so stock volunteer tees and a matching layer in the same color for events in both seasons. With about 112 days a year at 100°F or more, summer outdoor events work best at sunrise, with short volunteer shifts, shade and the lightest shirt the budget allows. About 11 inches of rain a year means an outdoor event here rarely needs a backup date, so put the budget into a bright volunteer shirt that photographs well in strong sun.

Which participant shirt suits a charity walk or run in Mesa?
A winter date and a light-colored, moisture-wicking shirt: 90°F heat fills much of the year, so December, with the lowest average high, is the easiest month for a race, and a long sleeve suits its cool start.
