September 2006 was an exceptionally hot month with a CET of 16.8C (the hottest on record in fact). The month was dominated by southerly air streams which brought very frequent high temperatures for the time of year.

The first third of the month saw a very warm and anticyclonic regime. This period was especially dry for most parts. Margate recorded 28C on the 6th.

During the middle third, the month then became more unsettled, with some very violent thunderstorms breaking out between the 11th and 14th. 30.2C was recorded at Heathrow on the 11th and there were also reports of some tornadoes forming in thunderstorms that hit Northern England around this time.

There was further heat and thunderstorms later on in the month. For instance 29C was recorded in the East Midlands on the 21st. The reminants of Hurricane Gordon then affect parts of Cornwall and Devon on the 27th, bringing storm-force winds, as well as dragging up more very warm and humid air.

Remember it well, an endless summer, August hadn't been great but July was fantastic and even August was better than many recent ones then September put the icing on the cake.

Summer 2006 was the last time I had to water my lawn, since then it just never stops raining long enough.

Also remember it well. The scary thing isn't the 37C recorded in July but the fact it was 10 years ago.

Very similar pressure patterns to this month. I think you need that for a very warm September: tropical maritime air and a reasonably strong airflow to avoid any low night minima.

It's notable by contrast that the warmest Mays have tended to have an Easterly component me intense sunshine. Different ingredients for different seasons. Like a record warm Dec needs constant warm frontal conveyor whereas a record warm Feb needs some sunshine thrown in.

Don’t rate it at all. Didn’t see any high temperatures and it wasn’t particularly settled. A lot of cloudy, humid weather which I hate and it barely went below 10C all month which is just horrible when it is supposed to be autumn. September 2004 was vastly superior and is the best September we’ve had this century.

September 2003 was my favourite because it came at the end of a good August, so it wasn't just a consolation prize. It was also very sunny down here.

Even in mid October 2003 the grass was yellow.
