My standard weather app is showing wrong temperature in my Iphone 6 ios 8.4 any solution ??

Tap Settings > General > Reset > Reset All Settings then restart your iPhone then try the weather app.

Wrong, based on what comparison?

Have you verified that the location in the weather app settings is correct? If it is, there's nothing else you can do. The data for the weather app comes from Yahoo, so you need to contact Yahoo about it.

Or get a different weather app, such as weather.com or weatherbug.

Dark Sky works nicely - and tends to be accurate - if it is available in your locale.

Have you checked that settings are correct in regards to Celsius/Fahrenheit?

If you could give us an indication as to what temperatures you are seeing, and what you expect to see we could advise if this is the issue.

In the bottom right corner of the Weather App you will see 3 lines. Tap that to reveal the list of Locations you have set for weather. There you will see a C/F indicator in the bottom left. Tap for your preference

OK, thats definitely a Celsius/Fahrenheit issue. See my post above. If still an issue, I will do a screen shot of my phone.

Very perceptive of you. I didn't think of that. Could be that I haven't had my 2nd cup of coffee 😉
