There may be a number of causes if Siri is unable to provide the current weather information. You might attempt the following troubleshooting steps:
Verify your internet connection: For Siri to access weather data, an internet connection is required. It’s possible that Siri won’t be able to retrieve the data if your connection is sluggish or inconsistent.
Make sure Siri is turned on: if it isn’t, you won’t be able to utilise it to access weather information. Go to your device’s settings and select Siri & Search to enable Siri. Toggle the switch next to “Listen for “Hello Siri”” to the on position.
Verify your location settings: Siri provides weather information based on the location of your device. Verify that location services are turned on.
Ask Siri correctly: Make sure you are asking Siri for weather information correctly. You can try asking questions like “What’s the weather like today?” or “Do I need an umbrella?” to get weather information.
