Water, weather and rainfall
Last year (2015/16) we had a failed Spring and adrier than usual Summer. Winter was roughly normal and so our dams filled as usual by the end of May. Last Spring was then very wet and we had enough warm days for the pasture to really come along.

Autumn this year has been dry-ish though and May this year is looking to be fairly dry after a s few days of rain this week. After the nice spot of weather coming through today, the rest of the month is looking like a wash if you'll pardon the pun.
