Approaching SJT I listened to the ATIS on 128.45.  The ATIS stated that the Tower was closed at 21:00 local and gave NOTAM information; but no weather.  I requested weather for SJT through the ACARS; and received the XA:53 local weather.  I noticed that the Commercial 1 approach charts noted that 128.45 was the ATIS and '(ASOS when Twr Inop)'.  I was curious why there was no weather broadcast on the ATIS.  I decided to contact SJT Tower to ask why the weather info was missing; expecting it to be an oversight.  The Tower answered; gave me the current weather; and stated that the funding had been requested for the ASOS to broadcast on the ATIS frequency; but that it had not yet been approved.  This means that the note on the Commercial 1 charts is in error; and that there is no weather information on the ATIS frequency when the Tower is closed.  This may not be a problem for ACARS equipped aircraft; but if the ACARS is deferred; and Tower is closed; it may be difficult or impossible to get current weather for SJT at a low altitude.  Perhaps the company could figure out an alternative means of obtaining current SJT weather when the Tower is closed and ACARS is deferred; and letting the flight crews know on the briefing pages; as the current briefing page states 'ASOS available via ATIS frequency' and is not correct.
Air carrier Captain reports that the note with the ATIS frequency for SJT stating that the 128.45 is for ASOS when the Tower is closed is incorrect according to the Tower Controller.
