What Irvine's weather means for companies
August brings an average high of 87°F to Irvine and roughly 35 days a year reach 90°F, so field crews need breathable polos and caps in summer while office staff stay in cotton. December lows average 43°F, so year-end gifts fit best as lighter layers: a quarter-zip, crewneck or cap gets more wear than a heavy parka. Highs of 70°F or more last 10 months, March to December, so short-sleeve polos and performance tees should make up most of a staff order, with one light layer per person. Rain is scarce, roughly 14 inches a year, so it seldom moves an outdoor offsite or company picnic, and caps and sun-friendly event tees deserve a place in the order.
