The Bureau of Meteorology says it has been a dry start to spring with lower than average rainfall in the Hunter during September.
Most of the region recorded average temperatures, but parts of the Upper Hunter experienced maximum temperatures a few degrees higher than average.
The warmest day for month was last Friday, with parts of the region reaching 34 degrees.
Williamtown forecaster Paige Butcher says rainfall was down more than 50 per cent in many parts of the region.
"Here at Williamtown the average is around 60 millimetres and we've only received 18.8," she said.
"A similar scenario for up the valley as well only really receiving under 10 millimetres where in general for September they normally receive more than 30 to 40 millimetres."
Ms Butcher says maximum temperature have also been higher in the Upper Hunter.
"Temperatures have remained relatively on average for the minimum temperatures," she said.
"Some maximums a little higher in the higher Upper Valley by a couple of degrees which probably has aided in some evaporation as well.
"So a little bit warmer and pretty dry is the over all scenario for September."
