Perth Wet Weather This Week? Now Is the Time to Check Your Stormwater

What the current Perth forecast is showing

Based on Bureau of Meteorology Perth-area forecasts issued on Tuesday 9 June 2026, conditions remain unsettled through mid-week. BOM showed a very high chance of showers for Tuesday 9 June, with forecast rainfall ranges around 3 to 10 mm across Perth-area locations, followed by a medium chance of further showers on Wednesday 10 June.

Forecast details can change quickly across the metro area, but the broader message is clear: Perth is in the kind of pattern where stormwater weak points tend to show up.

Why this matters before the wet season ramps up

Many stormwater problems do not become obvious in dry weather. They show up when rain starts arriving regularly: water pooling near paving, overflowing soakwells, runoff pushing toward the house, soggy lawns, blocked pits, and downpipes discharging into the wrong area.

Early winter is often the best time to catch those issues. If you wait until repeated rain events are already happening, small drainage problems can become disruptive very quickly.

What Perth homeowners should inspect this week

• Downpipes: make sure roof water is being directed into proper drainage, not dumping onto paving, garden beds or against the home.
• Drainage pits and grates: clear leaves, mulch, sand and debris so water can enter the system instead of backing up.
• Soakwells: watch for slow draining, bubbling, overflow or water sitting around the soakwell area longer than it should.
• Low points around the property: look for pooling near garages, alfresco areas, paths, retaining walls and lawn edges.
• Recent changes: new paving, extensions, patios, garden beds or landscaping can change falls and send water in the wrong direction.

Photos taken during wet weather are especially useful

If water is pooling or overflowing, photos taken during or just after rain make quoting much easier. Good photos usually include the water build-up, nearby downpipes, grates, paving levels, access paths and a wider shot showing where runoff is heading.

When it is worth getting the drainage checked

If the same area floods each time it rains, water is running back toward the house, pits are overflowing, or soakwells are no longer coping, it is usually worth getting the system looked at before the heavier part of winter arrives.

Depending on the property, the right fix may involve cleaning, repairs, extra pipework, new grates or pits, additional soakwell capacity, or a broader drainage upgrade.

A practical next step before heavier winter rain

You do not need to wait for major flooding to act. A quick inspection during a wet week can help identify whether the current setup is coping properly or whether it is already showing signs it will struggle later in the season.
