. This means that the weather in Wales is in general mild, cloudy, wet and windy. The country's wide geographic variations cause localised differences in amounts of sunshine, rainfall and temperature. Rainfall in Wales varies widely, with the highest average annual totals in Snowdonia and the Brecon Beacons, and the lowest near the coast and in the east, close to the English border. Throughout Wales, the winter months are significantly wetter than the summer ones. Snow is comparatively rare near sea level in Wales, but much more frequent over the hills, and the uplands experience harsher conditions in winter than the more low-lying parts. The mean annual temperatures in Wales are about on the coast and in low-lying inland areas. It becomes cooler at higher altitudes, with a mean decrease in annual temperatures of approximately for each of increased altitude. Consequently, the higher parts of Snowdonia experience mean annual temperatures of . At nights, the coldest conditions occur when there is little wind and no cloud cover, especially when the ground is snow-clad; the lowest temperature recorded in Wales was in conditions of this sort at

Rainfall varies across the country with the highest records being from the greatest elevations.

The combination of mountainous areas and Atlantic lows can produce large quantities of rain and sometimes results in flooding. The amount of snowfall varies with altitude and enormously from year to year. In the lowlands, the number of days with lying snow may vary from zero to thirty or more, with an average of about twenty in Snowdonia. Wales is one of the windier parts of the United Kingdom. The strongest winds are usually associated with Atlantic depressions; as one of these arrives, the winds usually start in the southwest, before veering to the west and then to the northwest as the system passes by. The southwest of Pembrokeshire experiences the most gale-force winds. The highest wind speed ever recorded in Wales at a lowland site was gusts of at

In addition, there were of common rough grazing, giving a total area of all the land used for agriculture purposes, including common land, of . In order of area planted, the arable crops grown in Wales were: foods for stock-feeding, spring barley, wheat, maize, winter barley, other cereals for combining, oilseed rape, potatoes and other crops. The grassland was predominantly permanent pasture, with only 10% of the grassland being under five years old. Compared with other parts of the United Kingdom, Wales has the smallest percentage of arable land (6%), and a considerably smaller area of rough grazing and hill land than Scotland (27% against 62%).

. According to the Welsh historian John Davies:
Thus was created the border between Wales and England, a border which has survived until today. It did not follow the old line of Offa's Dyke nor the eastern boundary of the Welsh dioceses; it excluded districts such as Oswestry and Ewias, where the Welsh language would continue to be spoken for centuries, districts which it would not be wholly fanciful to consider as ''Cambria irredenta''. Yet, as the purpose of the statute was to incorporate Wales into England, the location of the Welsh border was irrelevant to the purposes of its framers.
The boundary has never been confirmed by referendum or reviewed by a Boundary Commission. The boundary line very roughly follows Offa's Dyke from south to north as far as a point about from the northern coast, but then swings further east. It has a number of anomalies, but some were ironed out by the

. Cardiff is the capital city and had a population of around 346,000 at the 2011 census. This was followed by the unitary authorities of Swansea (239,000), Rhondda Cynon Taf (234,400), Carmarthenshire (183,800), Caerphilly (178,800), Flintshire (152,500), Newport (145,700), Neath Port Talbot (139,800), Bridgend (139,200) and Wrexham (134,800). Cardiff was the most heavily populated area in Wales with 2,482 people per square kilometre (6,428 per sq mile) while Powys had just 26. A high proportion of the Welsh population lives in smaller settlements: nearly 20% live in villages of less than 1,500 persons compared with 10% in England. Wales also has a relatively low proportion of its population in large settlements: only 26% live in urban areas with a population over 100,000; in comparison, nearly 40% of the English population live in urban areas larger than the largest in Wales. Another feature of the settlement pattern in Wales is the share of the population living in the sparsest rural areas: 15% compared with only 1.5% in England.
