Tips for traveling to Estonia in September
Looking for some tips for traveling to the sun, snow, or whatever you're aiming for Estonia? 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 Estonia 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
- For light showers, an umbrella or a thin and light rain cape is usually sufficient, while more rain may require rainwear and rain boots.
- When it’s cold you need warm clothes such as a hat, gloves and scarf. If you plan on varied activities it might be a good idea to pack flexible clothing and wear multiple layers, as you can then easily adapt and regulate the temperature. For example you may want to wear cotton closest to the body, covered by a waterproof layer of wool or synthetics and then some warm layer of for example wool, fleece or down.
- 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.
