Tricity has a temperate climate with warm summers and cold winters that can be very severe. Rain is possible all year round. Summer is the best time to visit when temperatures range from 70°F to 90°F (20°C to 30°C), but evenings can be cool enough to require a sweater. Winters are wet, cold and grey.
Tricity has a well-developed common transport system, in addition each city has its own. Here is described only the common part of the system.
Development of the Tricity was smoothed by the construction of the city train (SKM) 1951, binding the whole area from Tczew by Gdańsk, Sopot 1953, Gdynia 1956, Reda, Rumia to Wejherowo 1957.
The backbone of the Tricity is the inner highway. It starts in Gdańsk and goes through Sopot, Gdynia, Rumia and Reda to Wejherowo. It consists of 2-4 lanes in each direction.
In 1975 the dual carriageway Tricity Beltway (Obwodnica Trójmiejska) was constructed. It starts in the vicinity of Pruszcz Gdański and goes through the western districts of Gdańsk to Gdynia-Chylonia.
There is plan to build new line of Szybka Kolej Miejska to connect Baltic Arena with Gdańsk Lech Wałęsa Airport. The line should be ready for 2012 Euro games
Gdańsk Lech Wałęsa Airportis one of the three main international Polish airports. Its position is associated with a well-developed network of domestic and international transport connections provided in response to the growing demand for business and tourist travel.
The Gdansk Airport is located a mere 10 km from the centre of Gdansk, about the same distance from the centre of Sopot and 23 km from the centre of Gdynia. The continually expanding road system which connects the airport with the city centres allows drivers to cover the distances in about 15-20 minutes. The close vicinity of the Tri-city by-pass and junctions with state motorways nos. 1, 6 and 7 facilitates access from areas outside the Tri-city. The convenient location of the airport makes it easy for travellers and cargo carriers to transfer from air to road, and also to the railway network and seaports. Gdansk Lech Walesa Airport has its own railway siding which can be used for handling large lots of cargo dispatched by air.
The efficient Gdansk Airport operates even the biggest planes and allows thousands of tourists to visit the Pomerania province every day. Just in front of the main entrance to the passenger terminal the visitors can find a bus that will take them to the city centre. They may also chose to take a taxi that will take them wherever they want to go in the area of the Tri-City for a relatively small price.
