The National Weather Service predicts a dry night for Halloween 2021, with temperatures in the low to mid 60s for the most populated areas of San Diego County.
You’ll have to bundle up in the mountains, however, with temperatures dipping into the 40s. Halloween night temperatures in the deserts will be in the 50s to low 60s.
Sunset will be at 5:57 p.m. at the coast. Skies will be partly cloudy and winds will be light, so delicate costumes won’t be in danger of being blown apart.
Highs on Sunday before the trick-or-treating begins are forecast to be 64 to 69 near the coast, 68 to 73 inland, 72 to 77 in the valleys, 67 to 74 in the mountains, and 85 to 90 in the deserts.
After the spooky night, the San Diego area can expert seasonal temperatures and a morning marine layer.
“Southern California will be in a quiet weather pattern through the duration of next week as the jet stream remains off to the north,” the weather service said.
