During the first part of January in a normal year it is expected that the monsoonal trough line will extend from the Coral sea, through Cape York, NT, and over to the Indian ocean. This year so far is an exception. Currently the trough line is firmly bedded in the Coral Sea and curving round to the Indian Ocean well clear of the Australian continent.
A high pressure system in the Tasman Sea with a ridge extending up the east coast was the main influence of the week’s weather. This brought fine light winds and mostly overcast conditions to the Ranges. Light drizzle on Saturday precipitated 1mm into the rain gauges.
Monday morning was the coldest of the week with 13.9°C at 5.00am. The hottest day was Sunday with 28.4°C at 1.15pm; with a hear stress factor measuring 36.8°C.
