🌡 The weather here, in general

Chula Vista barely has a winter. The warmest month (August) averages 78°F and the coldest nights still sit around 49°F, a span of only 29 degrees. The year here is measured in humidity and storms rather than temperature.

It essentially never gets hot here: fewer than five days a year reach 90°F. Cold, not heat, is the season worth preparing for.

This is dry country — roughly 14 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.
