Main article: Topography of Paris
Paris is located in the north-bending arc of the river Seine and includes two islands, the Île Saint-Louis and the larger Île de la Cité, which form the oldest part of the city. Overall, the city is relatively flat, and the lowest elevation is 35 meters (114 ft) above sea level. Paris has several prominent hills, of which the highest is Montmartre at 130 m (426 ft).
Paris, excluding the outlying parks of Bois de Boulogne and Bois de Vincennes, covers an oval measuring 86.928 square kilometres (33.56 square miles) in area. The city's last major annexation of outlying territories in 1860 not only gave it its modern form, but created the twenty clockwise-spiralling arrondissements (municipal boroughs). From the 1860 area of 78 km² (30.1 mi²), the city limits were expanded marginally to 86.9 km² in the 1920s. In 1929 the Bois de Boulogne and Bois de Vincennes forest parks were officially annexed to the city, bringing its area to its present 105.397 km² (40.69 mi²).
Paris' real demographic size, or unité urbaine, extends well beyond the city limits, forming an irregular oval with arms of urban growth extending along the Seine and Marne rivers from the city's south-east and east, and along the Seine and Oise rivers to the city's north-west and north. Beyond the main suburbs, population density drops sharply: a mix of forest and agriculture dotted with a network of relatively evenly dispersed éparpillement of satellite towns, this couronne périurbaine commuter belt, when combined with the Paris agglomeration, completes the Paris aire urbaine (or Paris urban area, a sort of metropolitan area) that covers an oval 14,518 km² (5,605.5 mi²)[citation needed] in area, or about 138 times that of Paris itself.
Climate
Paris has an oceanic climate and is affected by the North Atlantic Current, so the city has a temperate climate that rarely sees extremely high or low temperatures. The average yearly high temperature is about 15 °C (59 °F), and yearly lows tend to remain around an average of 7 °C (45 °F). The highest temperature ever, recorded on 28 July 1948, was 40.4 °C (104.7 °F), and the lowest was a −23.9 °C (−11.0 °F) temperature reached on 10 December 1879.[13] The Paris region has recently seen temperatures reaching both extremes, with the heat wave of 2003 and the cold wave of 2006.
Rainfall can occur at any time of the year, and Paris is known for its sudden showers. The city sees an average yearly precipitation of 641.6 mm (25.2 inches).[13] Snowfall is a rare occurrence, usually appearing in the coldest months of January or February (but has been recorded as late as April), and almost never accumulates enough to make a covering that will last more than a day.
