Tomorrow’s temperature tops out around 22 C, drops to about 13 C overnight, wind 10 km/h, humidity 60 %, sunshine 70 %. My graphs show a mild uptick in perceived tempo fluidity when the air is warmer, but that’s a side effect – the dynamics of the piece itself drive performance, not the weather. So set the metronome, hit the dynamics, and if you want the “nice feel” you can try warming up the room a few degrees. I told you so.
