Sweden - Climate and Weather
Spring falls between March / April to May, summer comes in from June to August, autumn falls between October to November and winter begins from November / December ending in February / March time. When it comes to the weather and what to wear, Swedes always have a bag with them just in case the weather changes. Get yourself a bag and the essentials of walking boots, a waterproof jacket for all seasons, and sunglasses. Chilly spring days mean layers and long trousers plus thinner layers for milder days. Summer means lighter clothing with jumpers and trousers for the evenings. Autumn sees temperatures cooling down so make sure you have a range of clothing to suit the temperatures. During winter time it is necessary to have plenty of layers with rain and wind proof clothing. Knitwear, thick fleeces, boots and headwear are necessary to keep warm.

The environmental risks in Sweden are varied. Cyclones resulting in strong winds and storms comparable to hurricanes have ravaged Sweden in the past. Cyclone Gudrun in 2005 left over 400,000 homes without power for days, damaged a large number of forests and caused 20 people to lose their lives. Most recently Cyclone Xaver swept across Sweden in 2013. A further environment risk is landslides. With heavy rain, winds and unstable terrain it is common for low level landslides to occur all over the country on a frequent basis. Rarely do landslides occur on a large scale but in 1977 the Tuve Landslide in Gothenburg affected around 268km of land, crushing close to 70 houses. A road was destroyed, 9 people were killed and 600 were rendered homeless.
Floods brought on by heavy rain are common in Sweden. Covering roads, submerging cars and seeping into homes, flash floods are an unfortunate consequence of heavy rainfall. Such occurrences have led emergency services to put in place special evacuation procedures and warnings from Sweden’s weather agency SMHI.
