🌡 The weather here, in general

Riverside has four clear seasons. August highs average 96°F and January lows average 44°F.

Expect around 97 days a year at 90°F or above, concentrated in August. Heat illness climbs sharply on consecutive hot days, so the third day of a streak is more dangerous than the first.

This is dry country — roughly 15 inches a year. When rain does come it tends to arrive all at once, which is why flash flooding is a desert problem as much as a tropical one.
