South Brisbane is in for a sunny Friday, followed by a cloudy but warm weekend in the high 20s with slight chance of showers and high humidity on Sunday.

Daytime temperatures aren't the only thing getting warmer during spring.

Residents are also in for a warmer night's sleep, with almost six more nights of the season reaching at least 20 degrees when compared to the mid-1980s

Warmer nighttime temperatures are increasing across the board, particularly along the coast, where Cape Moreton also recorded 15 more spring nights of 20 degrees or above.

Susan Gribble cares for sick, injured or orphaned koalas with Koala Rescue Qld.

She has noticed how the changing weather patterns have affected the springtime breeding cycle of koalas, considered a 'vulnerable' species in southeast Queensland.

"(Years) back, koalas had a distinct breeding cycle around September to November, coinciding with spring arriving," Ms Gribble said.

However, in recent years Ms Gribble has noticed that koalas are breeding earlier, and puts this down to warming seasons.

"The winters are a lot warmer, and koalas are breeding throughout autumn and winter.

"Joeys are emerging from pouches out of season, which isn't ideal as the cool nights are still a bit much for the little ones... they haven't always furred completely."

Research from Harvard University found that warmer nighttime temperatures can reduce the amount of sleep people get.

In a study of 765,000 people, they found that when nighttime temperatures were hotter than average, people reported more nights of insufficient sleep.
