Temecula City Events

Climate

 

Temecula valley weather is comparable to the Napa Valley. Although Temecula is separated from the pacific by the Santa Rose range, Rainbow Gap funnels the mild beach climate into the valley. Average summer highs are 85 degrees and winter lows 39 degrees. Yearly average rainfall is approximately 14 inches.

 

 

Air Quality

 

Throughout much of Southern California, air quality does

not meet federal standards. Poor air quality results in

potential health hazards and often produces a hazy,

unattractive ceiling of smog above the basin. Unlike most

of Southern California, Temeculas air quality is very good. Air quality monitoring in Temecula in the early 1990s indicated that days with air quality standard violations were rare. This is due to the Lake Elsinore Convergence Zone, where coastal winds block air pollutants from the rest of the South Coast Air Basin. These conditions provide an environment where residents can breathe clean, fresh air, improving the quality of life.
