Weather and climate in Maldonado (Uruguay)

The climate of Maldonado (or San Fernando de Maldonado) is subtropical (according to the Köppen classification: humid subtropical climate - Cfa), with mild winters (from June to August) and hot summers (from December to March). The rains are well distributed throughout the year.
The city is located in the southeast of Uruguay, on the coast of the Atlantic Ocean, a short distance from Punta del Este (which is located in a small peninsula to the south) and San Carlos (which is located a few kilometers further north). There are also some lagoons nearby.



We are in the area of ​​Uruguay, which extends to the border with Brazil, where the summer is milder, due to the influence of the ocean, in fact the average temperature of the warmest month is just over 22 °C (71.5 °F, the threshold below which, under the Köppen classification, we speak of an oceanic climate - Cfb).
However, here too, during the day it can get hot all year round, in fact the heat records are around 28/29 °C (82/84 °F) even in winter. Instead, from December to March, in summer, there can be heat waves, in which the temperature reaches or exceeds 35 °C (95 °F). However, due to the sea breeze, the heat is less intense than in the interior of Uruguay. Furthermore, as happens in the rest of the country, the south wind is able to interrupt the hot and sultry periods, bringing pleasant (and sometimes very cool) weather for two or three days.
In winter, there can be cold waves from the south, during which the temperature can drop to the freezing point or a little below at night, and can remain around 8/9 °C (46/48 °F) during the day. Also, fog can sometimes form.
