Luxembourg, like neighboring Belgium and the Netherlands has a fairly temperate climate. Winters in Luxembourg City hover right around the freezing point (32° F (0° C)), while summers average about 65° F (18° C), although daily highs tend to be about 5-10° F (3-6° C) degrees warmer.
Wildlife
There are few mammals left in the wild in Luxembourg, although in the mountains you can still find deer and boar along with numerous smaller mammals. There is also a surprising amount of sea life for a landlocked country as the rivers and lakes are home to perch, carp, trout, and pike among others.
There is a large variety of birds that travel through Luxembourg as they migrate north and south. Depending on the particular species, these birds may stay a season or just stop by in passing to their final destinations.
