Weld Pass Weather Forecast & Warnings (0872)

Climate of the Gibson Desert

Weld Pass is situated in a high-latitude desert region of Western Australia, characterised by an arid climate and significant diurnal temperature ranges. Being far inland, the area lacks the moderating influence of the Indian Ocean, meaning the air is typically dry with low humidity. This lack of moisture leads to clear skies and intense solar radiation, followed by rapid cooling after sunset.

Seasonal Weather Patterns

During the summer months, this part of the state experiences extreme heat as high-pressure systems dominate the interior. While the region remains mostly dry, it can occasionally be influenced by the remnants of tropical lows or moisture tracking down from the Kimberley. These systems can bring sudden, heavy rainfall that transforms the dusty landscape and makes unsealed tracks impassable. In contrast, winter days are generally mild and sunny, though night-time temperatures frequently drop toward freezing under cloudless conditions.

Severe Weather and Hazards

The primary weather risks for Weld Pass include prolonged heatwaves and sudden dust storms driven by strong frontal systems moving across the southern half of the continent. Bushfires are also a concern during the drier months when lightning from dry thunderstorms can ignite sparse vegetation. Travellers should always monitor the forecast for signs of heavy rain, as the local terrain is prone to flash flooding, which can cut off access to the nearest settlements for several days at a time.
