Climate Acclimation trending down, even though running above 22 degree centigrade

I have been running in temperatures at or above 26 degrees centigrade for the last week… minimum daytime temperatures are 29C, nights are 25C.

Why has my heat acclimation started trending down from 82% to 75% over last two days, running every day at 26C+ and over 80% humidity.

Ten runs in 8 days, all 26C to 29C.

  • What temperature do you see in the activity? It is displayed in the map. 

  • Yes , temperature is shown in the bottom corner RHS, been 29, 29,29,27,27,26,26, had three rest days in nine days but not consecutive.  Acclimation Started trending down after Saturdays run, which was 26C, same happened yesterday

    Had been going up from 28% on 13th, levelled out for two days at 82%, then dropped to 77% on Saturday, and 75% on Sunday , running both days.

  • In contrary to temperature-based badges, it is actually unimportant what the map in Garmin Connect shows. The only temperature that matters, is the temperature that the Weather Widget on your watch shows in the moment of the start of the activity. If the weather data is not synced, the Acclimation will fail, even if the map in Garmin Connect looks up the temperature later. At your next run, double check that the weather widget on the watch shows a temperature above 22°C before you start the activity. If it shows wrong temperature, try syncing the watch with the app.

  • Thanks,

    I checked the watch widget and it was not updating, just showed ( ---   29/22) which I guess means it was showing no current temp and max / min day temps from last time it synched.

    When I opened the widget it just sat on "Waiting for data" with no response for several minutes then went back to the watch face screen, without synching. No temperature showing.

    I turned on and off, and after that the widget just shows ( --    --/-- ), even though connected to the phone app. Does not collect data, and returns to watch face screen.

    Seems there's a problem. 

    I was having trouble pairing Shokz Headphones on 19th so I carried out a watch software update (Fenix-6 Pro) that day, software is now version 27.00 ( I'm not sure what it was before). Headphones worked after the update, but the acclimation has not increased since 19th, and has been going down. Seems a bit to much of a coincidence.

    Ran software update again, and synched several times. 

    Weather widget is now showing the correct current temperature plus Max/Min temperatures.

    Thanks for your help.
