That proximity to water probably makes a difference for overnight lows especially. I'm 2km from the nearest coastline.Cyclone Tracy wrote: ↑Thu 01/11/2018 10:09 There might be a couple factors involved this year, including our own little microclimates
1.You have had much higher rainfall.
2. Not sure how close to the water you are, I'm only 200 metres from the water and the sea surface temperatures were significantly higher in the first half of the year with that marine heat. This assisted milder overnight lows for the first 7 months for my station.
