Tweed Range Weather Forecast & Warnings (2474)

Regional Climate Characteristics

The Tweed Range sits within a subtropical climate zone, characterized by high annual rainfall and mild temperatures. Because the range forms part of the Border Ranges National Park, the elevation plays a critical role in local meteorology. Orographic lifting often causes moisture-laden air from the Coral Sea to rise and cool, resulting in more frequent cloud cover and precipitation than seen in the flatter parts of the Richmond Valley.

Seasonal Weather Patterns

Summer months typically bring high humidity and the risk of significant thunderstorm activity. These storms often develop along the Great Dividing Range before moving eastward toward the coast. During this period, the region is also susceptible to the remnants of tropical cyclones or low-pressure troughs that can deliver heavy, sustained rainfall over several days. Such events are a primary driver of the lush rainforest environment found across the range.

In contrast, winter and spring generally see more stable conditions. The cooler months are dominated by high-pressure systems moving across southern Australia, which lead to crisp, clear days and significantly cooler night-time temperatures at higher altitudes. Frost is possible in the more sheltered gullies of the range during mid-winter, particularly when cold fronts move up from the Southern Ocean.

Severe Weather Risks

The Tweed Range is particularly vulnerable to East Coast Lows. These intense low-pressure systems can develop off the New South Wales coast, bringing destructive winds and torrential rain that can lead to flash flooding in the catchment areas. Additionally, the dense vegetation makes the region a focus for fire weather monitoring during the drier spring months if the preceding winter has seen below-average rainfall. Residents and visitors should remain aware of how quickly conditions can change in this mountainous terrain.
