SF Isotherm

Quick and dirty SF isotherm map.

Base map via the always wonderful SF Climate app.

Am completely guessing on how to draw isotherms, assume you do it the same way as a topographic contour line. But hey, color! (But someone please automate this so we can animate it, thanks.)

I’m a little suspicious of some of the values though — doubt those home weather stations are well calibrated. Still, 7×7 microclimates.

We need to cross-reference this with a IPA / PBR consumption map.
