Editing Sylt (section)

=== Climate ===
On Sylt, a [[marine climate]] influenced by the [[Gulf Stream]] is predominant. With an average of {{convert|2|°C|°F|abbr=on}}, winter months are slightly milder than on the mainland, summer months though, with a median of {{convert|17|°C|°F|abbr=on}}, are somewhat cooler, despite a longer sunshine period. The annual average sunshine period on Sylt is 4.4 hours per day. It is due to the low relief of the shoreline that Sylt had a total of 1,899 hours of sunshine in 2005, 180 hours above the German average.<ref>{{cite web |url=http://www.westerland.de/fileroot/service/download/Tourismusstatistik2005.pdf |title=Tourimusstatistik 2005 |language=de |publisher=Town of Westerland |access-date=28 September 2008 |archive-url=https://web.archive.org/web/20090815163342/http://www.westerland.de/fileroot/service/download/Tourismusstatistik2005.pdf |archive-date=15 August 2009 |url-status=dead}}</ref> Clouds cannot accumulate as quickly and are generally scattered by the constant westerly or northwesterly winds.

The annual mean temperature is {{convert|8.5|°C|°F|abbr=on}}. The annually averaged wind speed measures 6.7&nbsp;m/s (15&nbsp;mph), predominantly from western directions. The annual rainfall amounts to about 650 millimetres (25½").<ref>{{cite web |url=http://www.klimadiagramme.de/Deutschland/list2.html |title=List auf Sylt (climate chart) |publisher=Bernhard Mühr |date=1 June 2007 |access-date=28 September 2008 |archive-url=https://web.archive.org/web/20081011104603/http://www.klimadiagramme.de/Deutschland/list2.html |archive-date=11 October 2008 |url-status=dead }}</ref> Since 1937 weather data are collected at [[Deutscher Wetterdienst]]'s northernmost station on a dune near [[List, Germany|List]], which has meanwhile become automated. A number of commercial meteorological services like [[Meteomedia AG]] operate stations in List too.

Sylt features an [[oceanic climate]] that is influenced by the [[Gulf Stream]]. On average, the winter season is slightly warmer than in mainland Nordfriesland. The summer season, however, is cooler despite longer sunshine periods. The yearly average sunshine period is greater than 4.4 hours per day with some years exceeding the average sunshine for all of Germany. Also precipitation is lower than on the mainland. This is due to the low relief of Sylt's shoreline where clouds are not able to accumulate and rain off.<ref>{{cite web |title=Das Wetter auf Sylt: viel Sonne und eine frische Brise |trans-title=The Weather on Sylt: A lot of Sunshine and a fresh Breeze |language=de |work=[[Die Zeit|Zeit Reisen]] | access-date=23 October 2012 |url=http://zeitreisen.zeit.de/ratgeber/deutschland/sylt/das-wetter-auf-sylt-viel-sonne-und-eine-frische-brise}}</ref>
