Geography

Situated in the region of Île-de-France, Montgeron has an oceanic climate, with cool winters and mild summers, and has more precipitation than others in the central parts. The mean temperature is around 10.8 °C, with a maximum of 15.2 °C and a minimum of 6.4 °C. However, the actual temperatures recorded are 24.5 °C in July at the maximum and 0.7 °C in January at the minimum, but the records registered the maximum temperature of 38.2 °C on 1 July 1952 and the minimum temperature of -19.6 °C on 17 January 1985. Due to the lower urban density between Paris and its suburbs, a difference of one to two degrees Celsius is felt strongly. The amount of sunshine is comparable to the average of the regions of the north of the Loire with 1,798 hours per year. Precipitation is also distributed over the year, with a total of 598.3 millimeters of rain and an approximate average of fifty millimeters per month. Although Montgeron is away from the course of the Seine, major axes of communication cross at Montgeron, most of them inherited from before. It was crossed by the old National Road 6 (N6) but now the road takes a detour to the west of the city center; the route is now occupied by the Departemental Road 50 (D50). The road D50 intersects the east–west running Departemental Road 31 (D31), which the latter leads to the neighboring commune of Yerres. The new portion of N6 shares its northern part with the Departemental Road 448 (D448) which the latter follows the river Seine south to Corbeil-Essonnes. Recent development and heavy traffic have made access to the city center much more difficult, which accentuates commercial desertification. Since 1849, the Paris-Marseille railway passes through the northeast of Montgeron, now served by the…
