Weather definitely is on a trend of becoming hotter, swings are also unusual when we have some rain the temperature may fall down as low as 23 deg C, the very next day back up at 32 deg C.

Moving and living sub-tropical I kept hygrometer readings daily along with rainfall for about 20 years, I am sorry I stopped in 2000. Upkeep of graphs were interesting reading, for some reason, I cannot remember why I abandoned my daily readings.
