Weather Data

What does it look like when you click the weather bubble in the map?

Here is from my run this morning:

The weather is feched from a nearby weather station based on the GPS location of the watch. Why you get inaccurate or no data could be that you limited the access to your location. I only find settings for the weather widget but there might be some other settings that I haven't found yet.

You're not the only one having this problem.  I just ran with a 10 mph southerly wind, and Garmin Connect says it was 0 mph from the north.  Sometimes it is fairly close, but it's frustrating that it is not very consistent.  Strava, on the other hand, has very accurate weather info, and it is getting its GPS info from my Garmin watch.  So I doubt it is a location issue.

Did you check the weather station? Which weather station is used?

In my last run the weather station displayed in the bubble is 02513. I used this site to get the weather data from that station (the last number in the URL is the station number):

[https://weather.gladstonefamily.net/site/02513]

I compared the data from the weather station with what is displayed in the bubble in the map and it is the same and it was pretty much the same weather in the real world as well. My location and the location for the weather station are not the exact same so there will obviously be some difference.

Weather station is KRLD.  Temperature and humidity seem OK, but wind speed and direction don't match at all.  Appears that N and 0 mph are defaults when Garmin Connect can't read the data?  Seems odd since Strava can read the data...

Strava is probably using an other weather service. 

I should probably clarify that the wind speed and direction the weather station was reporting did not match what Garmin was reporting, but the temperature and humidity matched fairly well.

You can check raw data: F12 -> Network -> weather -> Response.

Or by loading it again in Console:

jQuery.getJSON(
    'https://connect.garmin.com/modern/proxy/activity-service/activity/ACTIVITY-ID/weather',
    function(i){console.log(i);}
);

To be sure if it's display problem or wrong data.

I checked some activities from Richland and it shows what's in weather JSON.

Some have wind 0, but it's similar to what's that weather site lists for this station in last X days.

According to this site, the weather station KRLD that Garmin is using for my area reported a wind speed of 7 mph from SSW for the time of my run (7am PDT).  It is interesting that there is some data that reads 0 mph, even though it was windy all day that day.  For my run today, the data was fairly accurate.

Yes, but site which e7andy linked has more frequent readings, if you open last 7 days list for that station, there are some 0 for wind. And the site you linked also has few 0.
So probably it's about not so accurate data from that station and result depends how frequent is taken.

I'm not sure about hour, as I can't match it exactly to results. An idea would be to look for more websites with data from that station and compare.
