FAQ: Why don’t you show Alaska or Hawaii?
The shorter length and sparser geographic coverage of the data records for our nation’s most far-flung states makes it difficult to combine those records with others from the rest of the United States in a single, consistent analysis. You can obtain climate statistics for individual observing stations from the National Weather Service Regional Headquarters’ websites for Alaska and Hawaii.
