Raggamuffin spokeswoman Sandra Roberts said ticket sales had picked up over the past couple of weeks and it looked as though they would sell about 20,000 tickets for the event.
"It's buzzing along now, people have just started to get that buzz and the weather's looking good," she said.
"People are just getting excited."
She said the artists were all excited about coming too.
Following the festival, Sunday through next Wednesday will see mainly fine weather with temperatures of up to 24C but showers are expected next Thursday and Friday.
Climate scientist for National Institute of Water and Atmospheric Research James Renwick said next week's rain was inevitable.
The country was experiencing La Nina weather conditions which meant mostly northeasterly winds, bringing moist conditions to the northeast of the North Island and reduced rainfall to the south. This was unlikely to change, Mr Renwick said.
So far this month 112mm of rain have fallen in Rotorua, 25 per cent above average.
There was a similar increase for Taupo with 101mm so far this month. Whakatane has had 82mm of rain so far this month, a drop of 3 per cent.
Mr Renwick said Niwa was revising its climate outlook for February through to March but at this stage he was unsure what the outlook would be for that period.
"I suppose at this stage there would be a similar kind of pattern going into March-April."
