A song once said “It Never Rains in California,” but songs in particular and the 1970s in general are not to be trusted, because it has already rained today — Tuesday, Oct. 31 — in Los Angeles.

But will it rain tonight? The Dodgers — down 3 games to 2 — are slated to begin Game 6 of the World Series against the Houston Astros at 5:20 tonight in Dodger Stadium.

And trick-or-treating traditionally begins just as the sun is going down for the younger set — and into the evening for older children and the not-so-young.

According to the National Weather Service, it will be about 65 degrees in the downtown Los Angeles area at 5 p.m. with a 9 percent chance of rain. The relative humidity will be about 60 percent.

By 7 p.m., the temperature should drop to 61 degrees, but the chance of rain will hold at 9 percent, and relative humidity should rise to 72 percent.

It should get increasingly cloudy around 11 p.m., with temperatures around 59 degrees and the chance of rain dropping to 7 percent and holding at that level through the morning hours.

So bring a sweater for sure, and maybe an umbrella just in case.
