Belgium shares borders with France (620 km), Germany (167 km), Luxembourg (148 km) and the Netherlands (450 km). Its total area, including surface water area, is 33,990 square kilometres; land area alone is 30,528 km2. It lies between latitudes 49° and 53° N, and longitudes 2° and 7° E.[citation needed]
Belgium has three main geographical regions: the coastal plain in the north-west and the central plateau both belong to the Anglo-Belgian Basin; the Ardennes uplands in the south-east are part of the Hercynian orogenic belt. The Paris Basin reaches a small fourth area at Belgium's southernmost tip, Belgian Lorraine.
The coastal plain consists mainly of sand dunes and polders. Further inland lies a smooth, slowly rising landscape irrigated by numerous waterways, with fertile valleys and the northeastern sandy plain of the Campine (Kempen). The thickly forested hills and plateaus of the Ardennes are more rugged and rocky with caves and small gorges. Extending westward into France, this area is eastwardly connected to the Eifel in Germany by the High Fens plateau, on which the Signal de Botrange forms the country's highest point at 694 metres (2,277 ft).[61][62]
The climate is maritime temperate with significant precipitation in all seasons (Köppen climate classification: Cfb), as is the case with all areas adjacent to the North Sea, including The Netherlands and much of the United Kingdom. The average temperature is lowest in January at 3 °C (37.4 °F) and highest in July at 18 °C (64.4 °F). The average precipitation per month varies between 54 millimetres (2.1 in) for February or April, to 78 mm (3.1 in) for July.[63] Averages for the years 2000 to 2006 show daily temperature minimums of 7 °C (44.6 °F) and maximums of 14 °C (57.2 °F) and monthly rainfall of 74 mm (2.9 in); these are about 1 °C and nearly 10 millimetres above last century's normal values, respectively.
