History

The area of the later city of Gdynia shared its history with Pomerelia (Eastern Pomerania). In prehistoric times, it was the centre of Oksywie culture; it was later populated by Lechites with minor Baltic Prussian influences. In the late 10th century, the region was united with the emerging state of Poland by its first historic ruler Mieszko I. During the reign of Bolesław II, the region seceded from Poland and became independent, to be reunited with Poland in 1116/1121 by Bolesław III. In 1209, the present-day district of Oksywie was first mentioned (as Oxhöft). Following the fragmentation of Poland, the region became part of the Duchy of Pomerania (Farther Pomerania), which became separate from Poland in 1227, to be reunited in 1282. The first known mention of the name "Gdynia", as a Pomeranian (Kashubian) fishing village dates back to 1253. The first church on this part of the Baltic Sea coast was built there. In 1309–1310, the Teutonic Order invaded and annexed the region from Poland. In 1380, the owner of the village which became Gdynia, Peter from Rusocin, gave the village to the Cistercian Order. In 1382, Gdynia became property of the Cistercian abbey in Oliwa. In 1454, King Casimir IV Jagiellon signed the act of reincorporation of the region to the Kingdom of Poland, and the Thirteen Years' War, the longest of all Polish-Teutonic wars, started. It ended in 1466, when the Teutonic Knights recognized the region as part of Poland. Administratively, Gdynia was located in the Pomeranian Voivodeship in the province of Royal Prussia in the Greater Poland Province of the Kingdom of Poland and later of the Polish–Lithuanian Commonwealth. The present-day neighbourhood of Kolibki was the location of the Kolibki estate, purchased by King John III Sobieski in 1685. In…

Geography

According to the Köppen climate classification, Gdynia has an oceanic climate (Cfb), strongly influenced by its coastal location on the Baltic Sea. The sea moderates temperatures throughout the year, producing relatively mild winters, cooler summers compared with inland Poland, and a longer transitional autumn season, with the annual mean temperature of about 8.8 °C and annual precipitation of 792 mm. The maritime influence is particularly visible in the seasonal temperature pattern. Spring temperatures rise more slowly than in inland areas because of the cold waters of the Baltic Sea, while autumn remains relatively mild due to the sea retaining heat accumulated during summer. Around the summer solstice, daylight lasts for more than 16 hours. The lowest pressure ever recorded in Poland – 960.2 hPa on 17 January 1931 – was measured in Gdynia. Annual precipitation in Gdynia is relatively evenly distributed throughout the year, with increased rainfall typically occurring during the summer months. Climate normals published by IMGW-PIB show annual precipitation totals of 750–900 mm, with the highest monthly values generally occurring in July and August. For 1991–2021 the monthly means are 55 mm in January, 98 mm in July and 86 mm in August, 792 mm annually. Annual precipitation in Gdynia is relatively evenly distributed throughout the year, with increased rainfall typically occurring during the summer months. Climate normals published by IMGW-PIB show annual precipitation totals of 750–900 mm, with the highest monthly values generally occurring in July and August. The event led to widespread flash flooding. Genoa lows typically bring 80 to even 130 mm in such episodes, most of it in a few hours. From October to March,…
