The northern Atlantic coast has warm summers (28 to 32 °C, but with relatively cool nights at 15 °C) and mild winters, with highs around 12 °C and lows about 2–3 °C. Occasionally, temperatures reach −10 or 40 °C, and rainfall is very scarce. The weather only gets a bit colder further south in Chubut, and the city of Comodoro Rivadavia has summer temperatures of 24 to 28 °C, nights of 12 to 16 °C, and winters with days around 10 °C and nights around 3 °C, and less than 250 mm of rain. However, a drastic drop occurs as one moves south to Santa Cruz; Rio Gallegos, in the south of the province, has summer temps of 17 to 21 °C, (nights between 6 and 10 °C) and winter temperatures of 2 to 6 °C, with nights between −5 and 0 °C, despite being right on the coast.
