Kirk again. I just posted about the heat. It’s supposed to get up to about 29 Celsius (about 84 Fahrenheit) today. I thought I’d check to see how that compares with historical temperatures and this is what I found. The blue is average daily highs for the month of May and red is for June. You can see that 29 is hot, even for June, much less May. You can also see that the trend is up – presumably the result of global warming.
I took the data from this webpage: https://www.data.jma.go.jp/obd/stats/etrn/view/monthly_s3.php?prec_no=86&block_no=47819&year=&month=&day=&view=a2
