Editing Santa Barbara, California (section)

==Climate==

Santa Barbara experiences a [[warm-summer Mediterranean climate]] ([[Köppen climate classification|Köppen]]: ''Csb'') characteristic of coastal California. Santa Barbara's weather was ranked number 1 in the United States in 2023–2024 by ''U.S. News & World Report''.<ref>{{cite web|url=https://realestate.usnews.com/real-estate/slideshows/best-places-to-live-in-the-us-for-the-weather#1|title=The 25 Best Places to Live for the Weather in 2023-2024|publisher=[[U.S. News & World Report]]|access-date=January 16, 2024}}</ref> Because the city lies along the ocean and parallel to the predominant westerly winds, sideshore and light onshore breezes moderate temperatures resulting in warmer winters and cooler summers compared with places farther inland.

In the winter, storms reach California, some of which bring heavy rainfall but the [[rain shadow]] effect of the coastal mountains can at times moderate or enhance the rainfall depending on local storm wind flows. Local rainfall totals can be enhanced by [[orographic lift]] when storms are accompanied by southerly flow pushing moist air over the Santa Ynez mountains, producing greater rainfall than in other coastal areas. [[Diurnal temperature variation]] reaches a maximum in winter due to lower humidity and the absence of summer fog. On average, only 1.7 nights have freezing lows.<ref>{{cite web|url=https://www.bestplaces.net/climate/zip-code/california/santa_barbara/93111|title=Zip 93111 (Santa Barbara, CA) Climate|website=www.bestplaces.net|access-date=August 4, 2019|archive-date=August 4, 2019|archive-url=https://web.archive.org/web/20190804190845/https://www.bestplaces.net/climate/zip-code/california/santa_barbara/93111|url-status=live}}</ref>

In general, summers are warm with very few hot days exceeding {{Convert|90|F}}, and winters are comfortable and sometimes warm with occasional cooler days topping out around {{Convert|54-58|F}}. Most days from December to February have highs of {{Convert|63-69|F}},
and most days from June to August have highs of {{Convert|72-84|F}}.

Summers in Santa Barbara are mostly rainless due to the presence of a high-pressure area over the eastern Pacific, but summer showers can happen due to tropical hurricane/Monsoonal flows that rarely reach the region; thunderstorms can also occur during the [[North American Monsoon]]. In the fall, afternoon or evening downslope winds, locally called "[[Sundowner winds|Sundowners]]", can raise temperatures into the high 90s °F (high 30s °C) and drop humidities into the single digits, increasing the chance of wildfires, along with their severity, due to downed power lines, etc., in the foothills north of the city.

Annual rainfall totals are highly variable and in exceptional years (like 1940–1941 and 1997–1998) over {{convert|40|in|mm}} of rain have fallen in a year,<ref>{{cite web |url=http://www.wrcc.dri.edu/cgi-bin/cliMAIN.pl?ca7902 |title=Santa Barbara (COOP) |publisher=Wrcc.dri.edu |access-date=May 20, 2012 |archive-date=July 16, 2018 |archive-url=https://web.archive.org/web/20180716223941/https://wrcc.dri.edu/cgi-bin/cliMAIN.pl?ca7902 |url-status=live }}</ref> but in dry seasons less than {{convert|6|in|mm|-1}} is not unheard of. Snow sometimes covers higher elevations of the Santa Ynez Mountains but is extremely rare in the city itself. The most recent accumulating snow to fall near sea level was in January 1949, when approximately {{convert|2|in|cm}} fell in the city.<ref>{{cite web |url=https://www.edhat.com/site/tidbit.cfm?nid=11115 |title=Snow in Santa Barbara |publisher=Edhat |access-date=December 20, 2015}}</ref>
