Darwin locals have had to layer up like never before during the wet season. Records tumbled in the Northern Territory's capital city on Tuesday as persistent rain kept a lid on the temperature throughout the day. Tuesday's maximum temperature of 21.9 degrees was Darwin's lowest on record for the wet season and the third lowest for any time of the year. It was also the coldest day in 49 years. As if this wasn't enough for a city whose average maximum temperature at this time of year is 33 degrees, it then got even colder in the evening. The mercury reached a low of 18.0 degrees shortly after 8pm amid the day's final drops of rain. This was Darwin's lowest temperature recorded during April for 69 years. Drier conditions this morning allowed the temperature to reach close to 25 degrees before midday and warmer weather will return later in the week. More typical maximums in the low thirties are expected on Thursday and Friday.
