@korina How often is HRRR updated in Windy? (HRRR is updated hourly by NOAA)

Overlay a grid of numbers on the map to show to show values for whatever is selected for display(wave heights, wind, etc.)

Putting the cursor over a spot does produce a number but it would be an added convenience to have a grid of numbers displayed over the entire screen. Other sites like Ventusky already have this capability.
