What San Diego's weather means for companies
About 16 days a year hit 90°F or more, enough heat that summer events need lightweight tees and outdoor staff need a cap, though one uniform set covers the rest of the year. Year-end gifts fit the climate best as lighter layers: with December lows around 45°F, a quarter-zip, crewneck or cap gets more wear than a heavy parka. With eight months of highs at 70°F or more, April to November, short sleeves are the default uniform, and a quarter-zip handles the remaining months. At roughly 11 inches a year, rain rarely interrupts outdoor work, so field uniforms should put sun protection, such as a cap and a light long sleeve, ahead of rain gear.
