The live forecast above shows Penrith’s weather hour-by-hour for today. This detail helps you plan around the day’s peak heat, potential showers, and wind shifts, which is especially useful during western Sydney’s hot summers and cooler winter mornings.
What does the hourly forecast actually tell me?
The hourly breakdown maps temperature, apparent temperature, chance of rain, wind speed and direction, and humidity for each hour of the day. For Penrith, this is most helpful in the late afternoon, when summer temperatures can spike above 40°C, or in winter when early fog and frost clear by mid-morning. Use it to time outdoor jobs, exercise, or travel to avoid the hottest part of the day.
How reliable is the hourly data for Penrith?
Forecast accuracy is highest for the first 24 to 48 hours. The Bureau of Meteorology updates this model several times daily, so checking the live forecast above before heading out gives you the best available view. For a longer outlook, the weather in Penrith 10 days and penrith weather 14 days pages show broader trends, though detail fades beyond a week.
Does the hourly forecast change much during the day?
Yes. The BOM refines the model as new observations come in, so what you see at breakfast may shift by lunch. Refresh the live forecast above if conditions look unsettled.
Can I use the hourly data for Penrith tomorrow?
You can, but confidence drops after 24 hours. For planning tomorrow, check the weather in Penrith tomorrow page for a more stable picture.
What does “apparent temperature” mean on the hourly chart?
It combines actual air temperature with wind and humidity to show how hot or cold it really feels. In Penrith, a 38°C day with low humidity can feel cooler than a 32°C day with high humidity.
