Climate data

Britain may be a nation of peculiarly obsessive meteorologists with a dearth of institution-destroying political action in the last fifty years, but a consequence of this is that we've got peculiarly wonderful climate data recorded, from which maps like this and this can be produced, leading to awkward questions like 'why isn't Ipswich, being as it is so dry and sunny, thronged by mobs of pasty English tourists'?

Does anyone know of such maps, at a reasonable resolution (being able to see individual Welsh mountains is clearly excessive, but this isn't really accurate enough) for continental Europe? It was clear that there was a lot of climactic variation between Gdansk and Krakow, I'd be interested to know what it is that balances out the sunniness of La Rochelle to leave it as unpopulated as it is.
