08Editor's notes
What the numbers don't tell you
July is peak tourist season and peak fog, with afternoons often below 18 °C at Fisherman's Wharf while Berkeley and the Napa Valley bake. The Fourth of July fireworks over the waterfront frequently vanish into the mist. Bring a jacket, and head to the Mission or Dolores Park for sunshine. Hotel rates are at their summer high. Rain does not fall.
The Stern Grove Festival brings free Sunday concerts, and the Fillmore Jazz Festival fills the first weekend. Alcatraz needs booking a month ahead. The cable car queues at Powell and Market are longest between eleven and three; the California Street line is the quiet alternative. Daylight lasts until after eight thirty. August is similar; see August, with Outside Lands the main event.
