Overcast weather means a cloud layer covers 90 percent or more of the sky, blocking all but the faintest sunlight. As the live forecast above shows, this often brings steady temperatures and reduced visibility—perfect for knowing whether you’ll need your jacket today.
How is overcast different from partly cloudy?
Overcast and cloudy are sometimes used interchangeably, but meteorologists draw a clear line. “Partly cloudy” means 30–60 percent cloud cover; “mostly cloudy” runs 60–90 percent. Overcast is the full grey lid—90 percent or more. While both reduce sunshine, an overcast sky feels distinctly dimmer and often signals a frontal system moving through. If you hear “overcast weather today,” expect persistent cover and a lower ceiling than a partly cloudy day.
What does the overcast weather symbol mean?
The overcast weather symbol appears on most weather apps and charts as a solid grey or black circle, often with a horizontal line. On Environment Canada maps it’s a filled-in cloud icon. If your app shows that symbol, you’re looking at an overcast sky. For anyone searching “overcast weather meaning in urdu,” it translates to ابر آلود (abr aalood) – a sky entirely veiled by clouds. This symbol is distinct from partly cloudy (a half-filled circle) and indicates no direct sunlight expected.
Frequently asked questions about overcast weather
Can overcast weather affect your mood or health?
Yes. Reduced sunlight can lower vitamin D production and in some people contribute to seasonal affective disorder. However, the cloud layer often moderates temperature extremes, making it a comfortable outdoor condition for many activities.
Is overcast the same as fog?
No. Fog is a surface-level cloud that reduces visibility to less than one kilometre. Overcast refers to the cloud ceiling above you; visibility may remain good despite a completely grey sky. Fog often accompanies overcast but isn’t required.
What’s the best overcast weather app for Canada?
Environment Canada’s WeatherCAN app provides official hourly forecasts and alerts. Many Canadians also use The Weather Network app. Either will show the overcast symbol and hourly cloud cover—look for >90% to know it’s overcast.
