of subpolar oceanic climate, thus being at the confluence of three climatic types. The February mean is just below the isotherm for that classification. Due to just three months being above 10 °C (50 °F) in mean temperatures and winter lows being so mild, Saint Pierre and Miquelon has a Köppen Climate Classification of Dfc, if bordering on Cfc due to the mildness of the winter and either Dfb or Cfb due to the closeness of the fourth-and fifth-warmest months to having mean temperatures at or above 10 °C (50 °F). Typical maritime seasonal lag is also strong with September being warmer than June and March being colder than December. The average temperature is , with a temperature range of between the warmest ( in August) and coldest months ( in February). Precipitation is abundant ( per year) and regular (146 days per year), falling as snow and rain. Because of its location at the confluence of the cold waters of the Labrador Current and the warm waters of the Gulf Stream, the archipelago is also crossed a hundred days a year by fog banks, mainly in June and July. Two other climatic elements are remarkable: the extremely variable winds and haze during the spring to early summer. Economy The inhabitants have traditionally earned their livelihood by fishing and by servicing the fishing fleets operating off the coast of Newfoundland. The climate and the small amount of available land militate against activities such as farming and livestock raising (weather conditions are severe, confining the growing season to a few weeks, and the soil contains significant peat and clay and is largely infertile). Since 1992 the economy has been in steep decline, following the depletion of fish stocks due to overfishing, the limitation of fishing areas and the ban imposed on all cod fishing by the Canadian Government. The rise in unemployment has been countered by state financial aid for the retraining of businesses and individuals. The construction of the airport in 1999 helped sustain activity in the construction industry and public works. Fish farming, crab fishing and agriculture are being developed to diversify the local economy. The future of Saint Pierre and Miquelon rests on tourism, fisheries and aquaculture. Explorations are under way to exploit deposits of oil and gas. Tourism benefits from the proximity to similar tourist areas of Canada.
