...but probably not as hot as it has been in the United States this past week. Heat wave records from Maine to Texas were broken in mid-July when temperatures of 100 degrees Fahrenheit and higher, coupled with very high humidity, affected millions of people and strained power grids everywhere. According to the Washington Post, the "proximate cause of this heat wave was a huge ridge of high pressure at the upper levels of the atmosphere, which led to sinking air that inhibits rainfall and boosts air temperatures. The clockwise circulation around the High helped pump humid air northward from the Gulf of Mexico. The abnormally strong high pressure cell peaked in the central states on July 17 and 18, and then stretched eastward, moving the bubble of heat with it as the week wore on."

Drink plenty of water. If needed, or if you need to be active in the heat, add electrolytes to prevent dehydration. Limit or eliminate alcoholic beverages, which are diuretics; they add to dehydration. So fill your wine glass with water, plenty of ice, and a splash of lemon or freshly squeezed lime rather than chardonnay.
