Wales has recorded its warmest September night on record, according to the Met Office.
The record was set in Aberporth, where a minimum temperature of 20.5°C was recorded for a 24-hour period leading up to Wednesday, September 8.
This means that the temperature did not drop below this point overnight on Tuesday, September 7.

The Met Office also described this as a "tropical night" as temperatures remained over 20°C.
It has beat a record first set in 1949, where the previous record was held at 18.9°C in Rhyl.
A high of 30.7°C was also recorded in Gogerddan on Tuesday, making it the seventh time in the last 50 years that temperatures have reached in excess of 30°C in the month of September in the UK.
The warmer than usual conditions for September are expected to remain for the rest of the week, despite a weather warning for thunderstorms having been issued for Wednesday and Thursday.
Some parts of the UK are expected to reach over 30°C. According to the weather forecaster, only six Septembers in the last 50 years have experienced temperatures above 30°C, with three of those occurring in the last decade (1973, 1999, 2006, 2013, 2016, 2020).
That warmth is no longer confined to the south as it was earlier in the week, with Scotland having a chance of hitting 28°C on Wednesday.

Met Office deputy chief meteorologist Dan Harris said: “The hot and clear weather currently being experienced across large parts of the UK is forecast to break down through the middle of the week as showers and thunderstorms arrive. These will initially affect the southwest of the UK on Wednesday, before moving steadily north and developing across most areas through Thursday and Friday.
“Thunderstorm warnings have been issued across a number of areas to highlight the potential for isolated impacts, including surface water flooding of homes and businesses, disruption to transport, and very isolated damage to infrastructure from lightning or hail. The semi-random nature of showers and thunderstorms means that many places will not see any thunderstorms at all, so it's not possible at this range to be more precise about the locations at risk, or indeed be more confident about the potential for impacts.”
Although there’s a degree of uncertainty looking into the weekend’s forecast, a gradual improvement is most likely, with the showers gradually being replaced by increasing amounts of dry weather with sunny spells, whilst temperatures fall back to nearer average for the time of year, the Met Office reports.
