The best time to visit Lithuania is late spring or summer, when there’s usually enough fine weather to allow you to stroll around the cities and make significant forays into the great outdoors. On the whole though, the only thing that’s predictable about the Baltic climate is the deep, dark winters – in all other seasons the weather can be changeable in the extreme.
Summers are relatively short (roughly mid-June to late August), and although you may well experience a string of hot, dry days during this period, showers and chilly nights are equally likely. Remember to pack a waterproof jacket and warm sweater alongside your T-shirts.
Temperatures cool down rapidly from mid-September onwards, although autumn can be an extraordinarily beautiful season in which to visit, with the golden brown leaves of deciduous trees contrasting with the dark-green pines.
The first snowfalls can come as early as mid-November, and by early to mid-December winter sets in with a vengeance. Average daytime temperatures can remain below zero right through until March, plummeting to minus 15–20°C in particularly cold spells. Winter can of course be a magical time, with lakes, rivers and large expanses of the Baltic Sea freezing over, and crunchy snow cover adding an air of enchantment to medieval city centres. However, rural areas can be difficult to get to without a four-wheel-drive vehicle (only the main highways are showploughed), and you’ll have to be well togged up in order to endure anything but the shortest of walks. Wherever you are in winter, some form of hat or head covering is absolutely essential.
Even when the spring thaw sets in, the countryside can remain grey and barren until well into April (or even May in northern Estonia), when a sudden explosion of colour transforms the landscape. The countryside takes on a green lushness, drawing cattle and horses out from their winter barns, while city-dwellers indulge in a frenzied stampede for the pavement cafés.
