35 Celsius = 95 Fahrenheit for my fellow yanks. That seems like a pretty extreme line to draw for "when do I need AC". I don't know about you, but the indoor temperature above which I start wanting AC is around 72-75F, or ~23C. Lots of the PNW gets over that for much of the summer. It didn't used to be this way, but I've wanted AC in Seattle for at least a few weeks a year, sometimes as much as 6 - 8 weeks, since 2013 or 2014. Particularly because the insulation in a lot of apartment buildings meant to make them more efficient in winter causes them to heat up like a furnace in a hot summer.
