(Spring) The beginning of spring is considered the period when the day’s average temperature rises and remains above 0oC. When the snow is starting to melt, when the rivers are breaking free after long months of confinement under the thick layer of ice, the nature is awaking. In the southern part of Latvia the arrival of spring is observed around March 20. Gradually it advances upwards. Arrival of the spring in the northeastern part of Latvia takes place later than in other parts of Latvia. During this season the amount of precipitations is smaller than during any other season. Anticyclone prevails. In May there is the smallest amount of precipitations and moreover, it is the sunniest month of the year. The gradual rise of temperatures can be suddenly changed by the sudden drops in temperatures, precipitations, often in the form of snow, which is the result of cold arctic air streams.

(Summer) Summer is the warmest season of the year, when nature processes are more active. Summer begins in the mid of June, when the apple-trees and lilac bushes have finished blossoming, and the day’s average temperature remains above 15oC. On June 21 sun is at its highest above the horizon and it is the longest day of the year. The temperatures are gradually starting to rise, and they reach their peak in July, and on the coast even in August. Changes in weather conditions are determined by cyclones and anticyclones. While anticyclone remains, southerly and southeastern winds bring warm and dry temperatures. The weather continues to be fair and warm. In this period the daytime air temperatures reach their peak when they occasionally exceed 30oC. For the second half of the summer cyclones bring humid air masses from the Atlantic Ocean and the Baltic Sea. Normally they are forming in July and August.

(Autumn) First frost means that the autumn has arrived. It is first noticed in the beginning of September in the northeastern part of Latvia. Then it will gradually spread all through the territory of Latvia, reaching the costal area only by the end of September. In the same way a little bit later the day’s average temperature will drop -10oC below zero - the period of active vegetation is over. In the second half of November autumn gradually turns into winter. The weather conditions in autumn are determined by the influence of the Atlantic Ocean and the Baltic sea. The character of autumn is defined by cyclones and anticyclones. In the autumn months the cyclone activity is observed. From the Atlantic Ocean cyclones bring cloudy weather, often precipitations. The rainy period is changed by the sleety weather - rain and snow. In autumn there can be a period of clear and sunny weather, which is called “The Indian Summer”. Normally it is determined by anticyclone, when from the south and from the southeast in the end of September or in the beginning of October warm continental air streams flow. Day temperatures can reach as high as 20oC. You can see the flocks of geese, cranes and other birds in the sky. Birds are migrating to warmer climates to avoid cold.

(Winter) Winter begins when the day’s average temperature drops and remains below 0oC. Lakes and reservoirs are getting frozen, the topsoil is getting frozen too and the ground is covered by the layer of snow. Normally it snows for the first time in the mid of November in the northeastern part of Latvia. The weather in winter, like in autumn, is determined by the frequent cyclones. Their influence causes temperature differences between the western and the eastern Latvia. In winter daytime air temperatures normally range between +5oC and -10oC. In the littoral area, as well as in the eastern Latvia, temperatures are dropping even lower. If the cyclones bring warm maritime winds, the thaw begins. More often thaws are observed in the littoral area and in general everywhere in Kurzeme. In warm winters thaws can be observed everywhere in the country. Moving across the cyclones, big temperature differences occur between the topsoil and the air from the upper layers, and as a result of that the mist develops. The increased humidity in the air causes the formation of hoarfrost. Cold weather sets in with the arrival of anticyclone. The eastern and northeastern winds prevail, thus, bringing in Latvia arctic continental air. In clear winter nights temperatures can drop as low as -25oC and even lower
