The four victims all succumbed to hyperthermia, which occurs when a body absorbs more heat than it can release. Two women, 81 and 83, died of the condition on Saturday, a day after two men, aged 78 and 88, succumbed in similar circumstances.
The deaths came towards the end of a seven-day heat wave in which temperatures soared as high as 109 degrees Fahrenheit (42.7 Celsius).
The heat wave started to ease on Sunday and the peak temperature on Monday was a much more comfortable 80 Fahrenheit (27C).
