To give you an idea, a haiku:
can't escape the fog
not too hot never too cold
who knows how to dress
And now, time for a very scientific + psychedelic breakdown of microclimates:
(click the map for a massive color freakout version!)
SUNNY + WARM:
Mission
Castro
Potrero Hill
Nob Hill
Bayview
North Beach
Chinatown
WARMISH / PRONE TO FOG or WIND:
Haight
Lower Haight
Hayes Valley
SOMA
SOMA
Downtown/FiDi/Tenderloin
CHILLY:
Inner Richmond
Inner Sunset
Outer (South) Mission
Excelsior
STRAIGHT UP COLD:
Outer SunsetTwin Peaks

You can use the peaks as your weather guide. The fog will come rushing in like water overflowing a full tub. Time to grab the hoodie and head for shelter!
(A 10 degree weather change seems like a big deal in SF since weather tends to vary btwn 50 -75 degrees throughout the year)
Overheard:
'I never know how to dress in this town.'Which is why I tend to lug around extra clothes/layers with me all day long..
but at least at the end of the night my bag is super light!
