After months of intense heat, the Monsoon’s rains bring joy and prosperity to India, but its seasonal downpours can disrupt transport, mining, and energy industries. As the Northern Hemisphere summer comes around, the Indian interior heats up significantly, leading to an area of low pressure over India’s north. Moist winds from the Indian Ocean, to […]
Globally, ocean temperatures are at record levels for the second consecutive year, and this has played a part in creating one of the costliest hurricane seasons on record in the North Atlantic. Forecasts are suggesting a similar impact of the hot oceans here in Australia for the coming tropical cyclone season. Link between hot oceans […]
A clear La Niña signal is starting to emerge in the central Pacific Ocean, however the declaration of La Niña depends on a few factors that are still a coin flip chance of occurring. What is La Niña? La Niña is the cool phase of the El Niño Southern Oscillation (ENSO) that occurs when cooler […]
Stretching high above Earth’s North and South Poles are two swirling columns of extremely cold air encircled by powerful winds. These whirlpools of frigid air and wind are each called the polar vortex, and they can have a big influence on weather patterns across the Northern and Southern Hemispheres. What is a polar vortex? A […]
Early last month, we said that May would be a make-or-break month for the positive Indian Ocean Dipole (IOD) that could be forming this year. Turns out, it has most likely broken. A positive IOD occurs when the trade winds along the equator blow to the west instead of the east, causing an upwelling of […]
Signs are pointing to the second consecutive positive Indian Ocean Dipole (IOD) developing in the next few months. However, May is shaping up to be a time to make-or-break this event. What is a positive IOD? The IOD is a coupled ocean-atmosphere climate driver that changes the circulation patterns over the Indian Ocean. A positive […]

Tropical Cyclone Mal is set to sideswipe Fiji overnight as a Category 2 or Category 3 tropical cyclone. Tropical Cyclone Mal developed into a tropical cyclone on Monday evening and has since increased in strength to a Category 2 system on Tuesday morning. As of 3pm Fiji time (FJT), Mal has sustained winds of 100km/h, gusting […]
One look at the map of rain predicted over Australia this week shows that part of every state and territory will see some wet weather during the next 7 days, with a few areas in line for a soaking. Image: Forecast accumulated precipitation between Monday and Sunday this week, according to the ECMWF-HRES model. […]
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 […]
