It's really hot in San Francisco right now. Like, really, really hot.

Temperatures in the Bay Area reached 106 degrees Farenheit on Friday. That's 106 degrees in foggy, chilly northern California, where late-summer temperatures are usually in the high 60s. The 106-degree day broke a record for all-time hottest temperature in San Francisco in recorded history, or at least 143 years.

A second consecutive day of extreme heat forecast for Saturday across the #BayArea and Central Coast. Take action to stay cool. #CAwx pic.twitter.com/n2X491El8c — NWS Bay Area (@NWSBayArea) September 2, 2017

Astonishingly hot along immediate coast in #SanFrancisco today. The current temperature exceeds the previous all-time maximum by 3F!!! #CAwx https://t.co/jkjjY5jjmQ — Daniel Swain (@Weather_West) September 1, 2017

The city isn't exactly prepared for record-breaking heat. Most places—homes and public spaces alike—don't have air conditioning. Residents were warned of a heat advisory and are doing their best to stay cool.

It's almost midnight. It's 85 degrees in our house. No one has AC in SF, so every window is open. This sucks. — Sharky Laguana (@Sharkyl) September 2, 2017

Hanging out in the only place in SF with AC... the car. #sfheatwave — Bethany (@b_sap04) September 2, 2017

Currently dying because it supposedly hit 106 degrees today in SF and there is no such thing as AC here :-) — 🍒Priscilla🍒 (@Literateaa) September 2, 2017

The weather in sf feels like a personal attack, no one has ac we're not prepared for this — AnaNicoleMurray (@AnaNicoleMurray) September 2, 2017

SF is great until it's 99 degrees and no one has AC — 🐇 (@TheKombuchaKid) September 1, 2017

San Francisco friends without air conditioning don't read this

When I lived in SF people thought I was nuts to have an AC. — Noah McCormack (@noahmccormack) September 1, 2017

First time I blast AC in my car at 5am in foggy San Francisco #heatwave — Charlie Blue (@charlie_thegirl) September 2, 2017

Stay safe out there, everyone. San Francisco, maybe it's time for backup air conditioning.
