"First, daytime temperatures were earth shatteringly boring, ie, they were exactly average. Second, for the first time ever [since 2006 when continuous monitoring began] we had no exceedances of the PM10 standard in June in Hastings," she said.
The Awatoto and Napier airshed also did not exceed the National Environmental Standard (NES) for particulate matter (PM10) of 50 micrograms per cubic metre (24 hour average).
"Rainfall was below normal across the region, particularly in Central Hawke's Bay and the south coast but because weekends were often manky, it felt like it rained all month.
"Groundwater and soil moisture lay comatose at May levels, while some river flows shuffled into the below normal category."
