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.
