Pack right for January

- 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.

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.
