Selma, California's Climate Profile: A Deep Dive into its Characteristics

Selma’s climate, categorized as a hot-summer Mediterranean climate (Csa) under the Köppen climate classification, is defined by its distinct wet and dry seasons. This classification highlights the area's warm to hot and dry summers, coupled with mild and somewhat rainy winters. Understanding these fundamental characteristics is key to grasping the overall weather in Selma, California, and its impacts.

Geographical Influences: Central Valley and Sierra Nevada

The geographical location of Selma within the vast San Joaquin Valley, flanked by the Sierra Nevada mountains to the east and the Coast Ranges to the west, profoundly shapes its weather. The mountains create a rain shadow effect, limiting precipitation and contributing to the arid conditions. Furthermore, they can trap air masses, leading to significant temperature inversions, especially during winter months. This geographical setup is a primary driver for the intense heat experienced in summer and the infamous Tule fog in winter.

Diurnal Temperature Range and Unique Microclimates

One notable feature of the weather in Selma, California, is its significant diurnal temperature range—the difference between daytime high and nighttime low temperatures. Due to clear skies and dry air, especially in summer, heat radiates quickly after sunset, leading to cooler evenings even after scorching days. This allows for some relief from the heat.
