SURF'S UP: Monster 7.5m 'freak' wave slams Coast

WET weather that had been expected to clear overnight has instead lingered with the formation of another coastal trough to make for a cloudy day of intermittent showers.

Forecaster Livio Regano said the Bureau of Meteorology had predicted Thursday afternoon to see the last of the system.

However another coastal trough had formed to replace the previous one that crossed the coastline overnight Wednesday and was now off the Capricorn Coast.

"We will see light rain through the day," Mr Regano said.

It follows falls in excess of 70mm at Bribie Island yesterday and up to 50mm around Noosa and Tewantin.

"We will have an unsettled couple of days where the showers will wax and wane," he said.

When it cleared what we won't see is a return to dry, cold south-westerlies with an easterly flow off the water expected to push in over the coast through the weekend.

Temperatures as a consequence would be warmer than average through next week, reaching a mid-week high of 25 degrees on the coast and up to 30 inland at places like Birdsville.

Night time lows would also be well above average in the mid teens. The highs and lows sit against June averages of 12 and 22 degrees.

Surfers could expect a punchy swell to reach the coast despite its predominantly southerly fetch, with a freak wave recorded at 7.5 metres by the Mooloolaba wave buoy.

Maximum wave heights at the buoy in 30 metres of water of Yaroomba were still touching 3.5 metres this morning.

The swell was being driven by strong winds blowing in the Southern Ocean for much of this week and the interaction of a Tasman high and a low south of the Great Australian Bight.

Expect a partly cloudy Friday to hit a daytime temperature peak of 23 degrees with light winds early becoming easterly at 15-20km/h before fading late in the day.

Saturday would be similar with the chance of light showers and light winds throughout before the chance of rain increasing Sunday.

It will hit 24 degrees on another light wind day with most rain coming in the afternoon and evening following a mostly-sunny start.

Monday would see zero chance of rain other than on the coastal fringe before the weather gives way to sunny skies and light winds through to at least Friday of next week.
