Shepparton's total June rainfall was 39.6 mm, slightly higher than the June average of 37.7 mm.

Rainfall levels last month were below average in large parts of Victoria; 26 per cent below the long-term June mean of 59.4 mm.
Despite the lower levels of rain in June, the year-to-date rainfall total is about 350 mm — 22 per cent above average.
Hunters Hill in north-east Victoria recorded the highest daily rainfall total for the month — 62.2 mm on June 21.
June was characterised by warmer than average days and cooler than average nights.
Many parts of Victoria experienced large areas of frost on June 9, when night-time temperatures plummeted due to clear skies and light winds under a strong high-pressure system.
Bureau of Meteorology long-range forecasting manager Andrew Watkins said there was a 50 per cent chance of La Niña forming in 2020 — double the normal likelihood.
“Tropical Pacific Ocean surface temperatures have cooled in recent weeks, and models suggest this cooling will continue through winter and into spring,” Mr Watkins said.
A La Niña event typically brings above average winter-to-spring rainfall for Australia.
The 2010 to 2012 La Niña event saw Australia's wettest two-year period, with widespread flooding in many parts.
July is expected to be drier than average but August is forecast to be a wetter month.
