In Australia, a 15-degree day can be a little chilly, but have you ever wondered why it feels colder in winter compared to the same temperature in spring? The simple answer comes down how long the day is. A longer day in spring allows more time for the air to heat up. But that doesn’t […]
A cold front swept through Sydney in the early hours of Sunday morning, but the temperature is four degrees warmer than on Saturday. So why is it warmer after the front? The cold front did indeed bring in colder air. The airmass temperature at about 1.5km elevation was 14°C on Saturday afternoon. On Sunday, it had […]
With the summer months quickly approaching we analyse how humidity will affect how hot it could feel this summer. While temperature is important in how hot it will feel, it is not the only factor. Humans and other warm-blooded animals typically cool off with sweat. This works by allowing the moisture to evaporate of the […]
Temperatures above 35 degrees are returning to the National Electricity Market as the lead-up to summer begins. Weatherzone’s forecast model Opticast predicts temperatures to reach 36°C at Rockhampton, 35°C at Gympie, and 34°C at Bundaberg, Cairns and Townsville. In the state’s capital, 35°C is expected for Ipswich, 34°C at Archerfield and 33°C for Brisbane City. All […]
Over the past year, there has been a lot of interest in building offshore wind farms off the Illawarra and Newcastle coasts of NSW. But why is this area receiving the most attention? The climate of the Illawarra & Newcastle Coasts The most important part of the Illawarra and Newcastle coasts’ geography is that they […]
A burst of heavy rain will soak Tasmania during the middle of this week, with potential falls in excess of 200 mm expected to cause flooding in the state’s north. A low pressure trough carrying copious moisture down from the tropics will drive thick clouds and heavy rain over Tasmania between Wednesday and Friday […]
Wild winds and rain battered South Australia earlier this week, but why did it cause thousands to go without power? A low-pressure system lingering in the Bight combined with a blocking high to the east delivered strong easterly winds and rain over the region. Strong easterly wind gusts between 60-80km/h was observed across Adelaide […]
Strong and gusty winds will produce several days of strong wind power across the National Electricity Market (NEM) this week. The satellite image below shows a band of cloud associated with a cold front and low pressure system passing southern on Tuesday afternoon. This low pressure system will extend multiple fronts across southeastern […]
Tasmania is having a spring-like day, with Hobart hitting 21ºC and thunderstorms building over the state. Northerly winds are carrying warm and relatively humid air over Tasmania today ahead of an approaching cold front. Amid this pre-frontal northerly flow, Hobart reached 20ºC shortly after 1pm and hit 21ºC just after 2pm. While this isn’t exceptionally […]
Australia’s tropical cyclone season is officially underway, but we may not see much activity for few months yet. The season runs from November to April, and for mining operators and businesses across northern Australia, 2026-27 is shaping up to be a season where the headline numbers and the real risk may not line up. On […]
A positive Indian Ocean Dipole is underway, but this one is unlikely to deliver the textbook dry spring and summer that businesses have come to expect from the pattern. The Bureau of Meteorology officially declared a positive IOD on Tuesday, October 27, which typically like El Niño can cause drier and warmer conditions over parts of […]
Waters off Indonesia have cooled in recent weeks, an indication that a positive Indian Ocean Dipole (IOD) event could be developing. It’s an important climate driver for Australia, and it could shape rainfall and temperatures heading into summer, with flow-on effects for farmers, energy and other industries. What is the Indian Ocean Dipole? The IOD […]
Leonora, WA, had its wettest September day on record earlier this month. Three weeks later, more than 1.3 million lightning pulses were detected within 800 km of the town in 48 hours. Why is a stalled trough delivering storms to mining country, and what it could mean for operations? The DTN Total Lightning Network detected […]
