9to5Google points out a new weather icon over the map layer has rolled out widely in the Android version of Google Maps with the current conditions and air quality (Maps also added dedicated wildfire and AQI layers in recent years). If tapped, it opens a tile showing the local forecast for the next few hours. This has existed in the iOS version for years, and some have seen it popping up on Android for months, but it might be new to you.
I presumed this would be a radar layer feature. Instead its essentially a widget shoved in. 👎
A radar layer feature ?
Something like this I guess. You can also add the air quality as a layer on top of GMaps. They probably didn’t do it this way because “weather” has more than one variable. A rain-radar-layer would be nice though…
