I would like to report an issue that concerns me: there was no incident at all; but I'm hoping that this submission may lead to action and improvement to avoid one! We all can learn. My home base; MMU; is not always the best on reporting weather. Often reports are missing only at MMU in all our bases; at other times the report will have obviously incorrect information; such as a dew point of 2 degrees on a humid summer day. A few days [we had] some of the most severe shear that I've seen aloft; and the challenge of the higher-minimum (roughly 600/2) GPS approach for Runway 05. The weather was almost unbelievable. We called the Tower from an intermediate stop. The weather was obviously wildly inaccurate; and the Tower confirmed. Towers need to check what they're sending out; and then check to see if that was what was published. Automation is great; but this is going to hurt somebody! We called after this report; and the Tower seemed unconcerned and unaware. On a day with some very strong conditions and weather near minimums. (The ILS to 23 is much better--had the wind been from the SW.) All of us on the safety team need to take pride and follow-up on our actions; is there any way that we can get towers to have a system to check on the accuracy of what's being put out there? Garbage out like this could really hurt some one; especially student and private pilots.
Corporate pilot operating out of MMU voiced concern regarding the inaccurate weather information being provided; the reporter suggested Tower personnel should verify automated weather observations before they are transmitted.
