Expect a warm day in Penrith tomorrow, so plan outdoor activities for the morning before the heat builds. The live forecast above shows the likely maximum, which will feel hotter in direct sun.
What will the temperature and conditions be like?
Penrith typically heats up faster than coastal Sydney due to its inland location. Tomorrow’s maximum will be in the low-to-mid thirties Celsius, with mostly sunny skies. A light afternoon sea breeze may offer brief relief, but it often arrives late. Humidity will be low, making the heat dry rather than sticky.
Should I expect any wind or storms?
Winds will be light in the morning, picking up from the east-northeast during the afternoon at 15–25 km/h. There is a low chance of a late thunderstorm, but most of the day will remain dry. Check the Penrith weather radar 128 km loop for any developing cells if you are heading out.
How does tomorrow compare to the rest of the week?
Tomorrow will be one of the warmer days in the Penrith weather 7 day forecast. A cool change is expected later in the week, bringing lower temperatures and a possible shower.
Is it safe to exercise outdoors tomorrow?
If you run or cycle, do it early before 9 am. The UV index will be very high, and the heat peaks in the mid-afternoon. Carry water and take breaks in the shade.
