The city lies on the northern edge of Pezara Bay, in a conurbation with the towns of Ramez and Victoria, and suburban communities, which together form a metropolitan area called the Turpol, with a population near 1,700,000. Port Isherwood has a population of 1,130,000, making it the largest city in Gerenia.
Port Isherwood was the very first Gerenian city founded, and it was built on the ruins of Serdste. Lord Samuel Isherwood disembarked at the place where the port is located today, and created a first settlement, which later became Port Isherwood. The Gerenian government gave the surrounding land to Lord Isherwood, and granted him the title of Life Mayor. However, he rejected his title after calling for an election, which was won by Dr. Claudius Häber.
The town quickly developed due to many factories and a shipyard being rebuilt, and it eventually became the largest city in Gerenia, and capital city of the region of Mäeklen (then Mayfield). Nowadays, the main economic activity in Port Isherwood is commerce, as most of the national companies are located there.
In September 2013, the status of capital city of Mäeklen was transferred to Klämen.
Port Isherwood enjoys a temperate climate, with cold, cloudy, moderate winters and mild summers. Average temperatures range from −1.0 to 17.2 °C (30 to 63 °F). In general it is a maritime climate and therefore damp, variable and mild.
The seasons are clearly differentiated. Spring starts in March and is initially cold and windy, later becoming warm and often sunny. Summer, which begins in June, is predominantly warm with plenty of sunshine interspersed with heavy rain. July and August are the hottest months. Autumn comes in September and is at first warm and usually sunny, turning cold and damp in November. Winter lasts from December to March and includes periods of snow. January and February are the coldest months with the temperature sometimes dropping as low as −15 °C (5 °F).
The industrial sections of the city are dominated by shipbuilding, food processing and chemical industries. Production of energy is also an important part of the local economy, as its plants generate up to 65% of the electricity consumed in Mäeklen.
There are many professional sports teams in the Port Isherwood and the Turpol area. Amateur sports are played by thousands of citizens and also in schools of all levels (elementary, secondary, university). This earned Port Isherwood the title of "Capital city of Sport". The most popular sports in Isherwood are football, ice hockey, tennis and sailing.
The main football clubs are International SC and Isherwood CSSC, which often clash in the so-called Isherwood derby. Their stadiums -International Sports Centre, and Elstree Road, respectively- are the biggest in the country, the first being the home stadium of the national football team.
