Baja California’s state civil protection agency (CEPC) expects a wet Halloween. Citing Mexico’s national weather service (SMN), it forecast showers with locally heavy rain across the state on Saturday, Oct. 31, in the afternoon and at night, with lightning and hail, lasting into the early hours of Sunday, Nov. 1, Uniradio Informa reported Wednesday night. A cold front is due to reach the northwest of the state on Saturday.
Before that, the agency sees isolated, on-and-off rain on Thursday afternoon and Friday morning in Tijuana, Tecate, Playas de Rosarito, Ensenada and San QuintÃn. Its outlook also calls for wind gusts of 50 to 60 km/h, waves of 1 to 2 meters on the Pacific coast and patches of fog, with lows of 16 to 19 °C in Tijuana.
Other outlooks published Wednesday point the same way. El Imparcial, citing forecasts it didn’t name, put the chance of rain at 55% on Friday, mostly overnight and early, 65% on Saturday and 95% on Sunday, especially in the morning, with highs of about 21 to 22 °C. San Diego Red, working from the Windy and Meteored forecasts, expected light but steady rain from about 4 p.m. on Saturday, getting heavier early Sunday and lasting into the afternoon.
What it means for the weekend
- Halloween night: the crowds on Avenida Revolución and the free SinfonÃa de terror y ritmo concert at the arch (9 p.m.) are outdoors. Bring a rain layer, or pick one of the indoor shows in our weekend picks.
- Sunday, Nov. 1: the downtown DÃa de Muertos parade and the first day of cemetery visits (hours and rules) fall on the day with the highest rain chances. Check the organizers’ channels before you head out. Clocks also fall back an hour at 2 a.m.
- Stay safe: the CEPC asks people not to cross arroyos, running water or flooded streets; to drive slowly with headlights on; to stay away from the beach while the surf is high; and to keep clear of trees, branches and signs that could fall. For emergencies, call 911.
Forecasts shift, so check the latest before you go out. Everything happening this weekend is on the calendar.
