wind direction in weather widget - what means O?

this may be a silly question, but i can't figure out what the "O" means (SE O, N O, S O....)

It's certainly not wind speed.

  • because i never saw any other value, regardless of the wind conditions

  • I also only see '0' as well.

    When I click through to the weather details it shows the correct wind speed but it never shows anything apart from '0' on this screen.

    Is this an issue on my side or Garmin's?

  • It used to be the wind speed in MPH (for those of us int he USA).  This too Garmin has broken.

  • that is a Zero 0 and not O, on the Australian Weather site (BOM) when its 0 wind speed(km/h) the direction defaults to N (0 or 360 degrees points north), when I am calculating Air Density for aerodynamics as a lower Air Density gives a faster riding speed.

  • ???

    It’s not southeast (SE) and north (0 degrees). 

    Not sure what air density has to do with this.

  • It is (S)outh (E)ast with 0 wind speed, I said the Australian Government site, when I have seen it display N for 0 Wind on their website, it doesn't mean other sites do the same in their algorithms, and in a further check in their data, they have placed Calm instead of a wind direction.

    "wind_dir": "CALM",
    "wind_spd_kmh": 0,
    "wind_spd_kt": 0

    As I said to Calculate CdA (Coefficent of Drag Area metre2) in cycling aerodynamics you need windspeed as a parameter and another parameter is Air Density which requires another set of parameters, weather sites dont calculate that, I'm calculating that, I have to know what each value mean and I prefer to test CDA when there is 0 wind (image 3rdpart connectIQ app using aeropod sensor)
