08Editor's notes

What the numbers don't tell you

March sees rain tapering off, with about eight wet days, and the first warm afternoons around 17 °C, with spring break visitors arriving mid-month and the Game Developers Conference filling Moscone for a week. Wildflowers appear in the Marin Headlands and on Mount Tamalpais. It is a good-value month before spring prices begin. The clocks go forward on the second Sunday.

St Patrick's Day brings a parade on Market Street. The baseball season opens at Oracle Park at the end of the month or in early April. Fog is still infrequent, so the Golden Gate views are reliable. Alcatraz needs booking about a week ahead. For the Cherry Blossom Festival in Japantown and Easter, see April.
