Tips for traveling to Portugal in September
Looking for some tips for traveling to the sun, snow, or whatever you're aiming for Portugal? Activities, weather, and clothing are closely linked. In addition, it's important to pack only what you really need so you don't have to worry about heavy packing or paying extra baggage fees.
Here is some advice on what to pack and what kind of activities you can do in the Portugal based on the weather that September is expected to bring. The advice applies to the country as a whole – local weather and possible activities may differ somewhat.
Pack right for September
- Sunshine does give you a nice color and a boost of vitamin D. However, if you don't have a lot of skin pigment, you should sunbathe carefully to avoid burning yourself, getting sun rash and, in the worst case scenario, skin cancer. This is where sunscreens and opaque clothing work particularly well. Another safe way is to stay in the shade when the sun burns the most, roughly between 9 am and 3 pm.
- 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.
