Parts of southeast Queensland have had their coldest night so far this month, after what has been a particularly warm and wet July.
Tuesday was Brisbane's first dry day in a week and the clearer skies combined with light winds to cause the mercury to plummet. It fell to eight degrees early on Wednesday morning, the coldest night so far this month.
It was also the coldest night of the month for Coolangatta and the Sunshine Coast Airport where it dropped to seven degrees, and Maleny where it cooled to four. For locals this was a rare opportunity to use their fire places, after becoming used to mild nights, with most places having seen warmer than average nights throughout the past three weeks.
The warm evenings have been due to persistent cloud and showers, causing locals to lament the absence of their usual fine winter weather, as July is usually one of the driest months of the year.
Rain has been recorded in Brisbane on 15 of the 24 days so far this month, well above the normal six days during July. The city hasn't seen this many rain days in July since at least 2004, with more than 150% of the usual monthly total recorded so far (37 millimetres).
It has been a similar story on the Gold Coast, with Coolangatta seeing a whopping 18 rain days so far. This is the most rain days it's had during July in 14 years and is closer to what normally occurs during the wettest months of February and March.
At the Seaway more than 60% of the days have seen rain, with a running total of 123mm making it the wettest July in five years already. Meanwhile, Maleny hasn't had as many rain days in July since at least 1994, with a running total of 20.
The cold weather experienced over night won't last long. A high pressure ridge will bring the return of moist onshore winds and the chance of a shower for the next week, leading to mild nights once again.
Brisbane can expect night-time temperatures to remain in the low teens each night until the end of July. This would make it the warmest July in at least 18 years in terms of minima.
