Pack right for September
- For light showers, an umbrella or a thin and light rain cape is usually sufficient, while more rain may require rainwear and rain boots.
- Warm - neither hot nor cool, are probably the most comfortable when you think of sunbathing. Shorts, shorter skirts or dresses, tank tops and t-shirts are the basics here. If you're going to a seaside resort, don't forget your swimwear and maybe even a snorkel, mask and flippers.
- 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.
