A hot weather hat is disclosed having a solar-powered Peltier-effect thermoelectric device mounted to a headpiece such that the cold surface of the thermoelectric device is in communication with the forehead of the wearer and the hot surface of the thermoelectric device is in communication with ambient atmospheric air. A thermally conductive strip provides conductive heat transport between the forehead and the cold surface. A finned radiator provides radiative and convective heat transport between the hot surface and ambient air.
