Climate - Parana (Argentina)

The climate of Paraná is subtropical, with mild, quite dry winters (from mid-May to mid-August) and hot, rainy summers (from December to February). In summer, the rains often occur in the form of thunderstorms.
The city is located in north-central Argentina, at 31 degrees south latitude, in the province of Entre Ríos, on the eastern edge of the Pampa, on the banks of the Paraná River, beyond which lies the city of Santa Fe.
Even though the winter is mild, there can sometimes be periods a bit cold, especially at night, when the temperature can drop to around freezing or a little below. This typically happens from late May to early September. In July 1976, the temperature dropped to -7 °C (19.5 °F).
During the day it can get hot all year round, in fact, the heat records are around 30 °C (86 °F) even in winter, in July and August. On the other hand, from September to February, there can be heat waves, in which the temperature reaches or exceeds 38/40 °C (100/104 °F). In January 2022 it reached 41.7 °C (107 °F).
But the Pampero, the south wind, is able to interrupt the hot and muggy periods, bringing pleasant temperatures (and sometimes even very cool) for two or three days.
