Fourth of July forecast: Hot and dry

Fireworks fans will be thrilled with the clear skies forecasted for the Bay Area this Independence Day, but firefighters are less than enthused about the hot, dry conditions.

While the heat isn’t expected to break any records, temperatures will climb in all parts of the Bay Area this Fourth of July, National Weather Service Forecaster Diana Hendersonsaid.

“It’ll be hot in some areas, very warm in others. On the good side, the sky will be clear and visibility for fireworks should be very good,” Henderson said.

According to the National Weather Service, downtown San Francisco and the San Francisco International Airport are expected to reach 74 degrees. Temperatures in Mountain View and Redwood City will likely climb to 86 degrees. Napa will reach 97 degrees and Santa Cruz will climb to 83 degrees, Henderson said.

The soaring heat is expected to be short-lived.

“It’s not a very long duration of super-warm temperatures,” Henderson said. “By the weekend, it should have gradually cooled. In most places we’re looking at upper temperatures in the upper-50s to low-60s. Along the coast, it’s going to go down to the lower 50s.”

Meanwhile, fire departments across the Bay Area will be on high alert. Capt. Joe Penko of North County Fire Authority’s Station 71 in Pacifica said his department will be doubling its staffing on the Fourth of July to ward against “the perfect storm” of high temperatures, low humidity and fireworks.

“Everyone who is available to work is working that day,” Penko said.

Pacifica and San Bruno are the only two cities in San Mateo County in which “safe and sane” fireworks are legal to purchase and use. The fireworks emit sparks and noise but don’t explode or soar through the air. However, Penko warned that the fireworks still present a danger and can reignite after they’re thrown away. He cautioned revelers to soak the fireworks in water after use and dispose of them in a metal garbage can.
