What San Diego's weather means for coffee shops
Roughly 16 days a year reach 90°F, and August averages a high of 82°F, so a summer tee release has a real season while hot drinks never leave the menu. Lows bottom out near 45°F in December, so a zip hoodie in the shop color is worth keeping by the bar for early shifts, even in a climate this mild. With highs of 70°F or more from April to November, eight months in all, a spring tee release and a late-summer one fit the calendar better than a single drop. At about 11 inches a year, rain is rare enough that a cart or farmers market stall can count on dry days most of the year, so dress that crew for sun rather than rain, in light colors with a light layer for early setups.
