National Weather Service explains why our weather records come from Logan, where the weather isn't the same as in much of the rest of Boston - Universal Hub

We receive a lot of enquiries why we don't move our climate site away from Logan Airport given it is perceived to be unrepresentative of Boston. Here's a thread on why it's not that easy from a bureaucratic standpoint or even climatologically desirable to move it

The primary purpose of the Automated Surface Observing Systems (ASOS) is to support Aviation and the Federal Aviation Administration (FAA) has the full say on the contract observer. The ASOS itself would only be moved ever if the FAA or Airport Authority needed it it moved.

The Logan site is not alone at being unrepresentative of the city is associated with. Cincinnati & Pittsburgh are two others with airports well outside city limits. Also, if we create a new site, it takes 30 years for new climate normals to become official.
