Tips for traveling to Laos in August
Looking for some tips for traveling to the sun, snow, or whatever you're aiming for Laos? 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 Laos based on the weather that August is expected to bring. The advice applies to the country as a whole – local weather and possible activities may differ somewhat.
Pack right for August
- For light showers, an umbrella or a thin and light rain cape is usually sufficient, while more rain may require rainwear and rain boots.
- Long, hot days bring risks - weather like this is one of the most challenging things we can do to our bodies. It's best to avoid going to Laos when it's so hot. Secondly, keep cool by staying in the shade, the pool or in an air-conditioned room. Pack clothes for the sun, for swimming but also for hydration.
- 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.
