In reply to Maestro:
One problem is that there are 162,000 routes in our Logbook system, and 50,000 registered users. Assembling a conditions report in a single page that will keep everyone happy is not possible so we will probably do it on a crag-by-crag basis.
We are working on something for the next set of Logbook upgrades, it will be a while though before we get round to this. For the moment though I expect all you really need is the Winter Conditions page linked to above.
