Question: The Swiss climate is generally temperate, but can vary greatly between the localities, from glacial conditions on the mountaintops to the often pleasant near Mediterranean climate at Switzerland's southern tip. There are some valley areas in the southern part of Switzerland where some cold-hardy palm trees are found. Summers tend to be warm and humid at times with periodic rainfall so they are ideal for pastures and grazing. The less humid winters in the mountains may see long intervals of stable conditions for weeks, while the lower lands tend to suffer from inversion, during these periods, thus seeing no sun for weeks.
Is there an answer to this question: What is typical weather in Switzerland during the summer months?

Answer:
warm and humid at times with periodic rainfall
