The conference is held in the beginning of autumn and Davos is located approx. 1500 m above sea-level. This means that temperatures will be lower than in other Swiss cities, ranging from an average of 5 to 18 degrees C. Though we hope for beautiful sunshine, make sure to bring warm clothing and an umbrella, as rain, wind and even snow are not uncommon at this time of year.


A cloakroom will be available during the Conference, where you can also deposit your luggage.

There is no obligation to leave a tip in restaurants, cafés, bars, hotels. The tip was in fact abolished 35 years ago and replaced by an all-inclusive bill.
However, the golden rule in restaurants is to round up the bill. For something like a coffee, round up to the nearest Swiss Franc. For something below CHF 100, round up to the nearest 5 or 10, and for bills over CHF 100 between 5–10 % is adequate depending on the quality of service.
