What Stockton's weather means for nonprofits
Roughly 90 days a year reach 90°F here, and August is the hottest month at an average high of 95°F, so an early start and a moisture-wicking shirt carry any summer volunteer day. Average highs fall below 65°F only from December to January, close to the year-end giving season, so a light hoodie sent with a donor thank-you gets worn while the weather is still cool. Mornings in December start at an average low of 39°F, cool enough that volunteers setting up before dawn will want a long sleeve they can shed once the afternoon calls for a tee.

Ordering from Stockton
Which participant shirt suits a charity walk or run in Stockton?
Short sleeves for most of the year, but choose the date with care: summer heat runs long here, so a race from December to January, when highs average under 65°F, is the comfortable pick, with a long sleeve for the start.
