Q - What do San Francisco, Calgary, Halifax and Santiago have in common?
A - Microclimates.
In this city, temperatures can vary as much as 9 degrees Fahrenheit from block to block, especially in the summer, and 30 degrees throughout the broader Bay Area.
Thus, the common advice to visitors here has always been to “dress in layers.”
Now there’s an iPhone app that can help you navigate the city’s terrain as well. SF Climates, from Baker Beach Software is the brainchild of Michelle Sintov, who after moving from the sunny Mission District to the foggy Outer Richmond, discovered the need for such a tool first-hand.
