Swiss Weather and climate
In Switzerland, the climate is moderate with no excessive heat, cold or humidity.
In summer, from July to August the daytime temperatures range from about 18 to 28 °C (65 - 82 °F) and in winter, in January and February, from about 2 to 7 °C (28 - 45 °F). In spring and autumn, the daytime temperature range is 8 to 15 °C (46 - 59 °F). Due to the altitude variation, temperatures might be different depending on the region.
It is highly recommended to visitors to pack a sweater, good walking shoes, sunscreen, sunglasses, a compact umbrella, and/or a light raincoat.
Switzerland has four seasons that are clearly distinguishable:
• In spring (March to May), the trees blossom and the meadows turn green. Sometimes in April, the winter returns for a short period and sometimes there are summer conditions as early as May.
• In summer, temperatures rise to 25 - 30 °C (77 - 86 °F), with temperatures exceeding the 30 °C (86 °F) mark during hot summers, and the Alpine vegetation flourishes.
• In autumn (September to November), the fruit ripens and the leaves of deciduous trees change colour.
• Winter was formerly generally cold and snowy, but now freezing temperatures and snow are no longer the rule, especially in the lowlands.
