Yeah, the layout of the house and lots of huge, openable windows could get you pretty far in terms of keeping it comfortable (most modern houses cannot do that, and are horrible even in moderate temps without AC) but if the breeze was weak and temps got past 90F nothing would help much. You could run a window AC non-stop all night and keep it close to 80, maybe, but that was still too uncomfortable to make it worth the insane electric bill that would follow (no insulation, original single-pane windows, no modern mostly-airtight envelope in the walls—I do mean the AC unit would run all night). Without that option we’d probably have had more like 5-6 patio-sleeping weeks per year, instead of 1-2.
