The falls effectively ended a roller coaster ride which started this year with good summer rain, followed by a dry March, a wet April and a dry May.

June was also heading for another dip in falls before an upward lift when the heavens opened up, firstly in the northern Wheatbelt as farmers tucked into their lunches last Thursday.

The rain pushed through most of the central, eastern, Great Southern and south coastal parts of the Wheatbelt on Thursday night and Friday, before a few scattered showers over the weekend.

According to the Bureau of Meteorology, falls ranged mainly in the mid-teens to tops of 40mm at Northampton, 38mm at Newdeate, 35mm at Morawa, 28mm at Narembeen and 12mm at Condingup.

Areas that witnessed a break in the weather included Wyalkatchem (0.3mm over three days), Borden (0.8mm), Three Springs (1mm) and Coorow (2mm).

Mullewa farmer Ian Broad said 38mm of "marvellous" rain fell on his property mainly on Thursday and Friday.

"Some of my neighbours got 45mm so we're all very happy," he said.

"We're a good six weeks in front of where we were last year and we've also got sub-soil moisture.

"It's the best start to a season I can remember and we're now looking forward to hopefully more moisture in July and August to kick the crops along."

East Pindar father and son farmers Sam and Zac Grima recorded 16mm on their home property with a leased property at Tardun receiving 30mm.

"This is great rain for our crops and stock," Zac said. "It hasn't been flash for a few years and we've had to sell some stock for cash flow but crops are looking good and heading into boot so if we get a wet July we'll be very happy."

Further north, Balla farmers Richard and Leon Allen established 4200ha of crop this year and recorded 20.5mm for the three days last week.

"It's shaping up as our best year since 1997 but it's a long way to go," Richard Allen said.

"We were getting a bit worried because May was one of our driest months and the crops were set to go off a bit this month.

"We took a punt with the wet summer and everything had to go in to get some cover after the last two poor years."

Richard's neighbour Chris Johnson established 4200ha and recorded 20.5mm for the three days.

"It's a great feeling especially this year when we know we've got good subsoil moisture," he said.

"We've had a few tough years but everybody is hoping this year will be kind to us and we get further rain to set the crop on its way.

"Right now we have to concentrate on spraying for leaf diseases while other guys in the district are spraying for bugs. But we should be able to get on top of things without too many dramas."

For Westonia farmer Ross Della Bosca the 20mm rain event on his property was a lifesaver and one of the best rain recordings for two years.

"We put in about 5000ha which was about 1800ha short of what we wanted to put in but we're happy with the rain," he said.

"Some guys have started seeding on this rain but mostly people bit the bullet earlier to get crop in.

"It was looking a little shaky and in some parts of the district crops are a little patchy but if we get more soaking rain things should change for the better."

Most farmers facing a difficult year east of Esperance had little joy from the system that lapped coastal areas.

According to Beaumont farmer Bill Tiller, the only event he recorded was wind.

"It blew a gale and probably stripped 800ha of our 8000ha programme," he said.
