Sky UV readings very different

Morning. Two readings about 10-15 miles apart in my city (Sudbury, Ontario). His UV levels are at least twice as high as mine. For my northern latitude, his readings are wayyyyy too high (11 range).

Just sending these example for study. Looking forward to updates that improve other readings also. My lower readings first pic, his house higher readings 2nd pic.
