      Two Sizzlers All Summer: 1971

      Weâ??ve mentioned and showed you many times before how the 1960s, in general, were cool summers. Many record lows were set during the summers of the 60s and the chill spilled into the early years of the 1970s.

      The summer of 1971 started with promise for warm weather enthusiasts. On June 27, 1971, Ironwood sizzled with a record high temperature of 97 degrees, while Marquette topped out at 96. However, this would be the hottest day in an otherwise cool summer. June 1971 came in just over a degree above average, while July and August were both over 2 degrees below. The thermometer in Marquette reached 90 degrees one more time in the summer of '71, on August 9.

      Last summer there were three days with highs of 90 degrees or above. That is right at the long-term average for a summer at the National Weather Service (NWS) near Negaunee. The greatest number of 90-degree days in the recent past was 10 in 2005. The summer with the most 90s since records have been kept at the NWS occurred in 1988. That torrid summer produced 13 days with highs of 90 degrees or above.
