San Diego weather facts every pet owner should know
- San Diego's warmest month, August, averages just a 77.3F high, meaning most of the year sits at or below the 77F caution line: arguably the best dog-walking climate of any big US city.
- January averages a 66.4F high and a 50.3F low, so even midwinter walks rarely call for a dog coat.
- Extremes still happen: San Diego hit 111F on September 26, 1963, so watch for fall Santa Ana heat spikes before afternoon beach runs.
- With no measurable snow in its normals and only about 9.8 inches of rain a year, mostly December through March, true indoor days are rare for San Diego pets.
