Kwinana weekend weather
This weekend in Kwinana, Western Australia, model by model. Weekend forecasts are far enough out that the models often split — so we show you where.
The models centre on about 17° across the weekend. Agreement is low — the weekend is genuinely up in the air at this range. Rain chance reaches 100% on at least one model. The models agree closely on temperature but split badly on rain (45 points apart), so the rain call is the uncertain part.

temperature and rain, judged separatelyThe models often agree on temperature and still split on rain — and rain is usually what decides whether a plan survives. A wide rain range means the shower is genuinely uncertain, not that the forecast is wrong.
