Please add Bernal Heights


Love the utility of the app! I do wish Bernal Heights was added though. Due to elevation, the weather on the hill is quite different than the surrounded areas on the map.



Totally inaccurate, full of bugs. For example today it says it is 60 degrees in SOMA and 50 degrees in the Mission. Seriously? Other times it shows North Beach as 20 degrees warmer than the rest of the city. It almost seems completely random how temps are assigned.

Recently updated and better than ever

I have really liked this app because of the ability to not only see San Francisco microclimates but also to watch how they are projected to change over the day. The app was in need of updating for a while and I reduce my rating accordingly, but it has recently been updated, all of the temperatures are accurate from present to past, it’s responsive, and they’ve added a new pane in which you can switch between San Francisco microclimates and Bay Area climates in general with the same ability to see temperatures change over the next 24 hours as predicted. My rating is back up to five stars! You get ads with the free version, and can pay a couple of dollars to get the ad-free version; very much worth it in my opinion.
