These 11 year record highs should be investigated further, looks like we started having these 11 year peak heat summers beginning in 1933 (so it's 1933, 1944, 1955, 1966, 1977, 1988, 1999, 2010).... I thought 2021 broke the cycle but it looks like 2021 was very similar to 1988 in that the peak heat was inland. The next one will be 2032. It doesn't mean other summers won't be very hot, it just means that the 11 year peak should be hotter than the summers around it.
