San Diego weather: Dense morning fog, warming trend this week
Dec 15, 2025
It’s going to be another warm, dry week for San Diego.
Low clouds and fog will move in again overnight and linger again Tuesday morning before clearing out for a sunny afternoon. Be careful if you’re on the roads early in the morning. We’ll likely be dealing with fog each morning this week.
Temperatures will stay above normal all week again as high pressure dominates the region. Thursday looks like the warmest day with highs back into the low 80s inland.
Once again, there is no rain in the forecast for this week. Some longer-range models are starting to show chances for the week of Christmas, but there’s still a lot of uncertainty this far out.
