Kardinya is currently experiencing the conditions shown in the live forecast above, typical of its coastal-suburban position 14 kilometres south of the Perth CBD.
What makes Kardinya weather distinct?
Its location between the Indian Ocean and the Darling Scarp creates subtle microclimate effects, particularly in summer when sea breezes arrive later than at the coast but earlier than inland suburbs.
- Summer maximums average 30–32°C, tempered by afternoon south-westerly sea breezes
- Winter minimums hover around 8–10°C, with occasional clear-sky frost in low-lying pockets
- Annual rainfall averages 750–800mm, concentrated between May and September
- The suburb’s tree canopy and parks can keep local temperatures slightly cooler than surrounding built-up areas on hot days
How does the daily forecast shift affect Kardinya?
Morning cloud from the coast often clears by midday, especially in spring and autumn, creating two distinct weather phases within a single day.
- Check the bom kardinya radar for approaching fronts, as rain arrives from the west-northwest
- Sea breezes strengthen from 1–3pm, dropping temperatures 3–5°C in minutes during summer
- Overnight temperatures in Kardinya tend to be 1–2°C warmer than inland suburbs due to retained heat from the urban area
- Perth weather forecasts apply generally, but Kardinya often sees slightly lower daytime maximums in summer
What is the best time to visit Kardinya for outdoor activities?
October to April offers the most reliable conditions, with March and April particularly comfortable as sea breezes remain consistent but extreme heat days become less frequent.
Can I get a reliable kardinya weather hourly forecast?
Yes. The live forecast above provides a detailed hourly breakdown for today and tomorrow, while the BOM’s Perth coastal forecast offers accurate wind and rain timing for the area.
Is Kardinya much warmer than Perth city?
On summer days, Kardinya is often 1–2°C cooler than the CBD due to closer proximity to ocean breezes; on winter nights, it can be 1–3°C warmer than inland suburbs thanks to urban heat retention.
