The Bureau of Meteorology predicts a combination of rain, wind and clouds across the three-day event.

Thursday’s forecast is a high of 21 degrees and a partly cloudy day with a very high chance of rain in the afternoon and evening and light winds.

The temperature is lower on Friday with a forecast of 15 degrees, along with a very high chance of showers throughout the day and winds during the evening.

Saturday’s temperature is forecast to be back up to 17, with a medium chance of showers and light winds.

Mr Woolley said the forecast was “manageable” and did not think it would deter Agfest patrons.

“Before I finished work to come up here [to Carrick] last Friday, I looked at the long-range forecast and it was looking pretty good.”

“And then I looked at it yesterday morning and it’s forecast three to 10 millimetres of rain and it’s meant to blow on Thursday.

“When they say rain between three and 10 millimetres, it’s like we’re going to get a little bit, but we don’t know how much,” he said.

The first-time chairman is philosophical about the Tasmanian autumn weather, saying it was to be expected in May as winter approached.

“It is Agfest weather, so you have to prepare for the four seasons in one day,” Mr Woolley said.

“From what I’ve looked at, except for the wind, it looks pretty mild. We’re not expecting 25 millimetres of rain; it’s meant to be reasonably warm.

“Bring a raincoat; we’ve got plenty of marquees to hide in,” he said.
