High Heaton Weather and Air Quality – September 2026

Weather

September was a generally warm with no cool spells, partly because the wind was from a westerly direction throughout the whole month. The average temperature was 14.6°C which is 1.2°C above the average for September. We have now had eight successive months with an average temperature not only above the mean, but substantially so. The month’s maximum temperature was 23.9°C at 2.45pm on Tuesday 22nd, and the minimum was 5.4°C at 4.45am on Tuesday 29th.  Rainfall returned to much of the country this month but most of it passed us by. Only 22mm of rain was recorded which is 39% of our average for September. A heavy shower during the late morning of Sunday 6th made that the wettest day with 7mm of rain falling in less than an hour.

Air Quality

The average PM2.5 particle concentration was 3.4 µg/m3, which is the lowest value for over 2 years, and well within the WHO target of 10 µg. The Air Quality Index was at level two on the last two days of the month and at level one on the other 28 days, so it was in the ‘good’ category throughout September.
