Finland weather can veer from maritime to coastal and vice versa, depending on the direction of air flow. This is because the main contributing factor to the disposition of Finland weather is its position between the 60th and 70th northern parallels in the Eurasian continent's coastal zone. Although situated in the same latitude as Siberia and south Greenland, Finland experiences temperatures several degrees higher than normal, mainly due to the impact of airflows from the Atlantic. Warmed by the Gulf Stream these airflows are responsible for raising temperatures in Finland, the Baltic Sea and the country’s inland waters being the other two main contributors.

Finland belongs wholly to the temperate coniferous-mixed forest zone and as such experiences cold and wet winters with temperatures averaging between 10°C at their warmest and no less than -3°C at its coldest. On average rainfall remains moderate through out the year.

Most parts of the Finland are under the influence of the 'föhn', especially during periods when westerly winds prevail. Caused by the Keel range this uniquely Finish weather phenomenon helps weather retain its predominant warm and clear characteristics.
Although the ocean has a rather moderate effect on the weather in Finland, on the occasion when the Asian continental climate extends its reach, putting the area under its spell, the country experiences severe cold conditions in winter, veering towards equally extreme heat during the summer season.

Although rapid weather changes are an on-going factor throughout out the year, they are more pronounced during the winter season, when the low-pressure system usually found near Iceland and the high-pressure systems in Siberia and the Azores impose their influences upon Finland weather patterns. As both systems have a tendency to vary greatly – position and strength wise – anyone of them can become Finland weather’s dominant factor, albeit a considerably lengths at a time.
