Cloudy Skies and Autumnal Chill: Perth Wraps Up March with a Cool Change

Cooler Temperatures to Conclude the Month

Perth is set for a notably mild and overcast conclusion to the month as a cloud-heavy system moves across the metropolitan area today, Tuesday, 31 March 2026. While the historical average for March often sees the city basking in temperatures near 29°C, today offers a distinct break from the heat. Residents should prepare for a day dominated by gray skies and a significant drop in the mercury, making it one of the coolest finales to March in recent years.

Morning: A Crisp and Cloudy Start

Early risers in the Perth Metro area encountered a crisp start to the day, with the minimum temperature dipping to 13°C. The morning is characterized by heavy cloud cover that moved in overnight, obscuring the sunrise which occurred at 6:27 AM. For those heading out for the early commute or morning exercise, a light jacket or sweater is highly recommended. Winds are expected to remain light, though the high humidity, sitting at approximately 63%, may make the air feel slightly damper than usual for this time of year.

Afternoon: Patchy Rain Possible

As we move into the afternoon, the weather will remain mostly cloudy. Meteorological data indicates the temperature will peak at a modest 20°C, a far cry from the scorching summer days earlier in the season. There is a 20% chance of rain throughout the middle of the day, likely manifesting as light, patchy drizzles rather than heavy downpours. While no severe weather warnings or wind alerts have been issued by the Bureau of Meteorology, the persistent cloud cover means that solar UV levels will be lower than the typical March average, though sun protection is still advised during peak hours.

Evening: Clearing Skies for a Calm Night

The thick cloud cover is expected to transition into partly cloudy conditions as evening approaches. Following the sunset at 6:14 PM, temperatures will begin a slow descent, hovering around 18°C by 9:00 PM and dropping further as the night progresses. The light rain risk will diminish after dark, leading to a calm and relatively dry night across the suburbs.
