About a week ago I took the liberty of comparing the PassageWeather predictions with Australian Bureau of Meteorology predictions. I looked at seven days forward for both.
They were very similar. South east winds (unusual for Sydney). This brought a week of rain.
In real life they matched actual weather
until it all improved (this morning, after seven days) about 12 hours earlier than forecast
I would expect that forecasts near major cities would the most accurate.
