Editing Södermanland County (section)

== Geography and climate ==
Södermanland runs between the lake [[Mälaren]] to the north and the [[Baltic Sea]] to its east and south. There is a large distance between the two main urban areas [[Eskilstuna]] and [[Nyköping]] of roughly {{convert|80|km|mi}}, and vast forested areas in between. The centre of Södermanland is spread out between four municipality seats namely [[Vingåker]], [[Katrineholm]], [[Flen]] and [[Gnesta]] that separate the southern and northern areas of the county. Most parts are low-lying being part of the [[Mälardalen|Mälar]] valley, but some higher areas can be found. The interior of Södermanland has many small rolling hills, courtesy of [[glacial rebound]] that has shaped the landscape of the area. The coastline on the Baltic Sea has many bays connected to it, with Nyköping being well-shielded from the open sea by a peninsula with plenty of inlets. Offshore there are also plenty of islets making up the Sörmlandic archipelago. The county has lake tripoints with Stockholm and Uppsala in Mälaren, with Västmanland and Örebro in [[Hjälmaren]] and a land tri-point with Örebro and Östergötland just south of [[Högsjö]]. The southwest of the county marks the southernmost points of the greater regions of [[Svealand]] and the [[Mälaren Valley]].

The climate much like other parts of southern Sweden is a mix between [[oceanic climate|oceanic]] and moderated [[continental climate|continental]]. Summers highs are most often around {{convert|23|C|F}}, with lows around {{convert|12|C|F}} inland and either near or above {{convert|14|C|F}} on the coast due to the warm July [[sea surface temperature]]s. Winter highs differ between {{convert|0|C|F}} and {{convert|1|C|F}} between inland and coastal parts with lows around {{convert|-4|C|F}} on the coast to {{convert|-6|C|F}} inland and in the lakeside north. It can heavily fluctuate between different years with influences from different weather systems. Most often winters are still pronounced enough for the climate to be a clear four-season climate although the open sea most often remains ice-free year round.
