San Diego homes aren’t cooling down at night the way they normally do—and there’s a reason for it.
Water temperatures off Scripps Pier recently reached 76.6 degrees, nearly 10 degrees above normal. At the same time, the cold-water upwelling that typically helps create our marine layer has stalled. The result is warmer, more humid nights and homes that hold onto the day’s heat much longer.
A few things that can help:
🪟 Close blinds on west and south windows by 9am
🔥 Keep the stove off, grill outside, or eat cold
💨 Run your bath and kitchen fans to pull humid air out
🚪 Shut doors to rooms you don't use
🧰 Seal gaps under doors and around windows
🌙 Wait until the outdoor temperature drops before opening up the house
But the bigger homeowner conversation is what may be coming next. NOAA is forecasting the possibility of a very strong El Niño this fall and winter, which could bring heavier rain and temporarily elevated sea levels.
Now is the time to look at your roof, gutters, drainage, and grading—not once the first major storm is already in the forecast and contractors are booked.
A little preparation now could prevent a much bigger problem later.
