Beg to differ, Ray. Acclimatization is a factor, but building design plays as significant role as well. My house in Miami is designed to be sewn up tight as a drum... it is not designed for natural air circulation, and opening those windows that can be opened at all does not materially change airflow. We also don't have fans everywhere, since they'd only ever be used in exceptional circumstances like these. So when the A/C goes, you sit in hot, humid, still air with no circulation, getting hotter and hotter and hotter.
In Guatemala, my house is being designed with walls of glass where over half the lateral surface can be opened up, and it's all intended to happen with organic airflow. No A/C will be installed at all. But my house in Miami looks and acts very differently.
