Pack right for August

The weather makes a difference when it comes to packing - especially which items should go in your suitcase. The tips below are designed to help you pack light and right without carrying more than necessary.
  • Cool weather is between warm and cold. This means you can bring long pants and/or a longer skirt and an extra sweater. Be aware that cool days can alternate with cold nights - it may be wise to also pack a hat, gloves and a scarf.
  • Light winds are probably most comfortable in hot weather but is cooling in cool and cold weather. If it is hot (when the air temperature is about 30 degrees), the wind can have a warming effect. A thin, windproof jacket and long trousers help to counteract these effects.
  • High humidity means that the air conducts heat to and from the skin more easily. For example, if the air is hot (above skin temperature), it will be harder to stay cool. On the other hand, if the air is cool or cold, it is more difficult to stay warm. In high humidity, the choice of clothing makes less of a difference. However, your physical activity plays a bigger role.
