The Swiss and Liechtenstein climate is generally temperate, but can vary greatly, from glacial conditions on mountaintops to the often pleasant, nearly Mediterranean climate at Switzerland's southern tip.

In Zurich, July is statistically the warmest and sunniest month of the year, with an average daily high temperature of 24.0°C (75.2°F). Summers generally tend to be warm and humid at times with periodic rainfall. Everything is possible, so be prepared for days of continuous rain at temperatures not exceeding 15°C (60°F), for days of constant sunshine at temperatures of up to 35°C (95°F) or, most likely, a mixture of both.

Recommended Equipment

One of our excursions will bring our guests on a mountaintop at 1’797.5 m (5'889 ft.). For this and other outdoor excursions and activities during the IPhO week we highly recommend you to bring:

  • good shoe gear

  • sun protection (e.g. sunglasses, suntan lotion)

  • rain protection (umbrella and/or rainproof jacket)

  • cloths for both warm and cold weather

Water quality

The drinking water that comes out of Swiss or Liechtenstein taps is of very good quality and can be drunk without concern.


The voltage in Switzerland and Liechtenstein, as in most of Europe, is 230V/50 Hz. If you travel with a device that does not accept 230 Volts at 50 Hertz, you will need a voltage converter. Read the specifications on your electrical device carefully. Switzerland uses type C (2-pin) and the rather uncommon type J (3-pin) plugs, (Type C 2-pin plugs also fit J sockets). For all other plugs (i.e. for laptops), an adaptor will be needed.
