As someone who is currently dating someone who is half egyptian and have visited egypt before, I think I can say I know a little bit about the country, and from I understand, the HIGH of 40 doesn't happen there often if at all, maybe overnight lows, when people are inside and sleeping but not highs. No house or building has heat there for a reason. Just remember 40 is the high, so he will be experiencing 20 degree weather on his visit as well. Obvouisly I don't know how much it will impact his decision, but just looking at it from the outside, probably impacts him more than most, esp since he has an offer from florida where can stay in warm climate and remain in the state he currently resides. I am not sure his family situation, but egyptian culture is usually very family orientated, they usually don't move out until marriage and any income is shared amongst the whole family until you move out, etc. why I think it would be difficult get him to leave, unless his whole family moves with him here, which I can see happening if does pick us from what I know about the culture.
