Sunny, warmer days should prevail in San Francisco and on the Peninsula through the Fourth of July weekend, but evening fog could threaten fireworks displays in some coastal areas.
Barbecuers and game-goers can rest easy: Daytime highs are expected to range from the mid-60s to lower 70s in San Francisco, while in San Mateo County temperatures will rise into the 70s and even the lower 80s in some of the warmest areas, according to Charles Bell, meteorologist with the National Weather Service.
However, as night falls, the fog should begin to creep in, and might reach some inland areas as early as 10 p.m., according to Bell. That typical July marine layer is expected to stick around overnight and then burn off again by midmorning throughout the weekend.
When it comes to fog and fireworks, “It could be a close call,” Bell said. “Though, in some respects, there could be some neat effects, watching the fireworks with the clouds coming in.”
However, when it comes to fireworks and fog in San Francisco, Pyro Spectaculars — the company responsible for all the pyrotechnics — has a few tricks up its sleeve, according to Pier 39 spokeswoman Cathy Paver.
“If it’s foggy, they’ll change out the shells for something that flies a little lower and looks better under a bit of cover,” Paver said.
To get the best views, visitors may want to turn up early and stake out a good spot. Pier 39 is expecting a larger crowd than usual since July 4 falls on a Friday — meaning most people don’t have to go back to work the next day, according to Paver.
