when does the weather warm up in los angeles
Climate of Los Angeles Summers are warm to hot, and nearly completely dry. The summer temperature pattern usually begins in late June or early July, and lasts through September or October, although it may start as early as late May. In August, the average high/low at the University of Southern California downtown campus are 84.8 °F (29.3 °C) and 65.6 °F (18.7 °C). The same figures at the LAX airport, approximately 12 miles (19 km) to the southwest and near the ocean, are 76.6 °F (24.8 °C) and 64.2 °F (17.9 °C). However, temperatures across the region sometimes exceed 90 °F (32 °C) during the summer. This happens when an atmospheric high-pressure area becomes dominant over the Great Basin of Nevada and Utah (a frequent occurrence), and the resulting offshore flow of the atmospheric air mass shuts off the normal coastal sea breeze in Los Angeles. July, August and September are the hottest months, with September holding the all-time record of 113 °F (45 °C). Skies are nearly constantly sunny, unless interrupted in late spring and early summer by the June Gloom pattern, which is unpredictable year-to-year. The North American Monsoon can bring occasional thunderstorms and high humidity to Los Angeles in the summer and early fall.
Climate of Salt Lake City The city has four distinct seasons: a cold, snowy winter; a hot, dry summer; and two relatively wet transition periods. The climate of the Salt Lake City area is generally subhumid, not semi-arid as often claimed. Under the Köppen climate classification, Salt Lake City has a hot-summer humid continental climate (Dfa), with relatively drier summers than the rest of the year.[citation needed] The Pacific Ocean is the primary influence on the weather, contributing storms from about October to May, with spring being the wettest season. Snow falls frequently during the winter, contributed largely by the lake-effect from the Great Salt Lake. The only source of precipitation in the summer is monsoon moisture moving north from the Gulf of California. Summers are hot, frequently reaching above 100 °F (38 °C), while winters are cold and snowy. However, winters are warmer than one would expect at this elevation and latitude, due to the Rocky Mountains to the east and north that usually block powerful polar highs from affecting the state during the winter. Temperatures rarely fall below 0 °F (-18 °C), but frequently stay below freezing. Temperature inversions during winter can lead to thick overnight fog and daytime haze in the valley as cool air, moisture, and pollutants are trapped in the valley by surrounding mountains.
