A different view of "hot"

Growing up in North Texas, "hot" was 38C+ (upper 90sF), when you just wanted to stay in the air conditioning all day. Well, I've discovered a new definition of "hot". It's a lot further down the thermometer - "only" 30C (85F), but, because we have no a/c and everything here is built to retain heat (and our apartment has no repeat no cross-ventilation) it's also 30C inside. Nor does it cool down much at night. Don't mean to whine, it was just a surprise last summer, and this is an early heat wave this year. Hope it cools down soon!
