Thunderstorms on the Horizon: Perth Braces for a Damp Thursday

Morning: A Stormy Start to the Day

Perth residents should reach for their umbrellas and prepare for a wet start this Thursday, March 26, 2026. Forecasts indicate a significant shift in the current weather pattern, with isolated thunderstorms expected to roll through the metropolitan area during the early hours. The morning will begin with a mild minimum temperature of approximately 19°C. However, rising humidity—currently sitting near 59%—will likely make the air feel somewhat muggy as the day begins. With a 55% chance of rain during the daylight hours, the morning commute may be hampered by sudden downpours, and commuters are encouraged to allow for extra travel time to navigate potentially slippery roads.

Afternoon: Peak Temperatures Amidst the Clouds

As we head into the afternoon, the mercury is set to climb to a maximum of 29°C. While this temperature is typical for late March in Western Australia, the conditions will remain predominantly overcast. The "feels like" temperature may hover slightly higher due to the moisture levels, making for a relatively warm and sticky afternoon. Winds are forecasted to persist from the east-northeast at roughly 24 km/h, which may bring some relief to coastal suburbs but will likely keep the storm clouds hovering over the city center. Despite the thick cloud cover, the UV index is expected to hit a moderate rating of 3. Even with the sun partially obscured, the threat of skin damage remains present for those spending extended periods outdoors, so sun protection is still recommended.

Evening: A Damp and Cloudy Transition

As the sun sets at 6:20 PM, the likelihood of further intense thunderstorm activity is expected to diminish. However, the clouds are not predicted to clear just yet. The evening forecast calls for overcast skies and a lingering 35% chance of light showers. Temperatures will begin their slow descent toward an overnight low of 18°C, providing a relatively comfortable night for sleeping, though the humidity may keep the air feeling heavy. Outdoor evening events may need contingency plans, as the damp conditions are likely to persist well into the night before clearing later in the week.
