I have what appears to be the same issue. I can't be sure it never updates, but
just now it was at least three and a half days out of date (with an update
interval set to 30 minutes). I can force updating by right click->Weather
Forecast Settings->OK.

I'm guessing it works properly for many people, or this would have been fixed
long ago. So I bet this bug depends upon the configuration. I even have a guess
(based on pure speculation!) about what's going on. My laptop travels between
work (wired connection) and home (wireless). I suspect the crucial detail is
that my KNetworkManager requires a password, my KWallet password, to set up the
network (I have it storing my WEP key). Thus we get the following sequence of
events:
1. When I boot up/log in, the network is not yet available, because I haven't
been given the opportunity to type in my password to start the network.
2. KWeather gets started first, and tries to fetch the forecast. Obviously,
this fails.
3. I then type in my KWallet password, and the network connects.
4. If I wait a few hours, I'm pretty sure (~90%) that the weather applet does
not update on its own, but I haven't tested this in a while.
4. I force the weather applet to update (right click->Weather Forecast
Settings->OK).
5. Unfortunately, the weather applet does not seem to recover from its initial
confusion. Perhaps there's a time-scheduling bug (note I also use ntpdate to
set my clock, and this too requires the network, although the time is still
available through the hardware clock when this fails), or a "disable updates if
network is unavailable" bug, or something along these lines.

If there's some way I can check on my system for when the next "run the weather
update" process is scheduled, I'd be happy to look.
