I just updated the Web page that describes the climate in my neighborhood, to reflect temperatures in September and October. For the years 2006-2016, the daily average low in October was 59F; but this year (2017) it was 64F. For 2006-2016, the daily average high in October was
81F; but this year it was 85F.Previously, I noted a new extreme high since 2006. In August this year, the daytime high reached 112F! Almost every time I add a month's daily high and low temperatures to my spreadsheet, I find a warming trend for that month.
