Dry is best; 3°C (37°F) wet feels worse than -25°C (-13°F) dry because it just seeps into the bones and sucks hardcore. I'm glad to live inland... (Also, 122°F is 50°C which sounds like someone left the sauna warming to the last minute, so how the hell is one supposed to wear clothes in that?)

Putting up thick curtains on the front windows should help! Figuring out how to get the heat to circulate is trickier – selective door-openings and door-closings, or setting up internal curtains to chop up the air mass of open-plan floors? If your house is at all usefully constructed, running the fireplace will warm up the structures, keeping the house warm for much longer than it's actually on.
