One of the better quintessential 'subtropical' East Coast Aussie climates..... north eastern coastal NSW. From memory about as far south as sugar cane is grown commercially in Australia. Bananas are grown commercially a bit further south at Coffs Harbour.
Grafton is renowned Australia wide for the Jacaranda Festival in November. The tree species itself ( Jacaranda mimosifolia ) is an excellent indicator of the subtropic regions of the world... it struggles in cooler temperate climates, and might well be killed off during severe cold and frosty conditions. Also, does not thrive and/or flower in true tropical conditons; ie in Darwin/Cairns/Townsville, the tree will grow, but stubbornly refuses to flower.
Grafton has excellent climatic data records, with there being several official BoM sites in the town as well as newer AWS sites on the outskirts of the City.
There are several long term sites within the City itself as well as an Airport AWS and a long term site at the Grafton Reserch Station with data dating back to 1917.
Climate:
Grafton has a humid subtropical climate (Köppen: Cfa, Trewartha: Cfal) with significantly more rainfall and higher temperatures in summer than in winter. Rainfall is lower than in stations directly on the coast, but monthly rain totals can often surpass 300 millimetres . The wettest month since records began was March 1974 when Cyclone Zoe produced a monthly total of 549.0 millimetres (21.61 in), whilst during periods of anticyclonic control and strong westerly winds monthly rainfall can be very low; for instance in August 2017 only 0.2 millimetres fell. Grafton gets around 115.2 clear days on an annual basis. Grafton like many NSW regional centres, is affected by heatwaves in the summer months. On 12 February 2017 Grafton recorded a maximum temperature of 46.3 ºC , the city's highest recorded temperature since records began.
