The region sweltered through its warmest May day on record at multiple weather stations, before temperatures crashed back to more normal winter temperatures within weeks.

The previous record of 27°C had stood since 2005.
The heat extended into the night, with the overnight low of 16.6°C recorded on May 3 also setting a new mark for the town's warmest May night, eclipsing the 16°C recorded in 1995.
