An average low for the month is 19°C, while the average high reaches up to 25°C. Those two temperatures remain basically constant in the course of the month. The overall average day temperature this time of year is 22°C, which is quite high by any means.

Sea Temperature

The sea temperature is equally as high as the air temperature, averaging 22°C, making for pleasant afternoon weather for swimming in the Atlantic Ocean.

The beginning of the month is the driest part with a 35% chance that rainfall occurs, while the end of the month has a chance of rainfall of 45%. Light rain is the most common type, being observed on 42% of those days with rainfall. Moderate rain, drizzle and thunderstorms occasionally happen as well, respectively on 22%, 20% and 14% of the wet days.

Cloud

Cloud cover increases significantly throughout September, from 78%, which already is quite high, to 87%, which is basically as high as the percentage of cloud cover ever gets in this region. The end of September is characterised by mostly cloudy skies.

Sunshine

This, of course, greatly limits the amount of sunshine that hits the city and its sandy beaches. September has the lowest number of daily sunshine hours per day on average. October, which is a similarly cloudy month, has the same number.
