Howick Weather Forecast & Warnings (6450)

Regional Climate Characteristics

Howick is positioned within the Mediterranean climate zone of southern Western Australia, characterized by cool, wet winters and warm, dry summers. Its location near the coastline means the local weather is frequently dictated by the movement of high-pressure systems across the Great Australian Bight. These systems often bring onshore flows that can moderate temperatures compared to the harsher heat found further north in the state's interior.

Seasonal Weather Patterns

During the winter months, Howick is subject to vigorous cold fronts that sweep up from the Southern Ocean. These systems are the primary source of the region's annual rainfall, often bringing steady showers and gusty south-westerly winds. In contrast, the summer months are defined by clearer skies. However, the locality remains susceptible to significant heat events when northerly winds draw hot air down from the desert, though the coastal proximity often provides a late-afternoon sea breeze that assists in cooling the area.

Severe Weather and Hazards

As with much of southern Western Australia, Howick faces specific seasonal risks. During the warmer months, the combination of high temperatures and dry vegetation makes bushfire weather a primary concern for residents and land managers. While tropical cyclones rarely reach this far south in a direct sense, the remnants of such systems can occasionally track across the coast, resulting in heavy unseasonal rain and flash flooding. Additionally, the southern coastline is known for powerful swells and hazardous marine conditions, particularly during the passage of intense low-pressure systems in the winter and spring.
