what is the average temperature of san diego california
Climate of San Diego Average monthly temperatures range from 57.3 °F (14.1 °C) in January to 72 °F (22 °C) in August, although late summer and early autumn are typically the hottest times of the year with temperatures occasionally reaching 90 °F (32 °C) or higher.[3] Snow and ice are rare in the wintertime, typically occurring only inland from the coast when present. "May gray and June gloom", a local saying, refers to the way in which San Diego sometimes has trouble shaking off the fog that comes in during those months. Temperatures soar to very high readings only on rare occasions, chiefly when easterly winds bring hot, dry air from the inland deserts (these winds are called "Santa Ana winds").
San Francisco San Francisco has a warm-summer Mediterranean climate (Köppen Csb) characteristic of California's coast, with moist mild winters and dry summers.[91] San Francisco's weather is strongly influenced by the cool currents of the Pacific Ocean on the west side of the city, and the water of San Francisco Bay to the north and east. This moderates temperature swings and produces a remarkably mild year-round climate with little seasonal temperature variation.
Palm Springs, California Palm Springs has a hot desert climate, with over 300 days of sunshine and around 4.83 inches (122.7 mm) of rain annually.[95] The winter months are warm, with a majority of days reaching 70 °F (21 °C) and in January and February days often see temperatures of 80 °F (27 °C) and on occasion reach over 90 °F (32 °C), while, on average, there are 17 nights annually dipping to or below 40 °F (4 °C);[95] freezing temperatures occur in less than half of years.

Corona Spectroscopy measurements indicate strong ionization and plasma temperature in excess of 1,000,000 kelvins,[1] much hotter than the surface of the Sun.
