The data show that there were warm periods during the latter half of the 18th century, and that the 19th century was a relatively cool period. An early 20th century warming culminated in the 1930s, followed by a smaller cooling that lasted until the 1960s. A warming trend has persisted since then.
Lithuania experienced a drought in 2002, causing forest and peat bog fires. The country suffered along with the rest of Northwestern Europe during a heat wave in the summer of 2006.
