Colors of the following climate diagrams: Madeira Azores
Daily maximum temperatures
The highest daytime temperatures in Azores are reached in August with an average of 25.9 °C. The coldest month, on the other hand, is February, with an average of just 17.0 °C. In Madeira, August is the warmest month, with 26.6 °C. There, it is coolest in February with an average of 19.3 °C.
Night time lows
At night, it cools down to varying degrees depending on the country and altitude. In Azores, temperatures drop as low as 12.2 °C in February. The warmest nights are in August with 19.9 °C. In Madeira, it is coolest at night in February with 13.8 °C and warmest in August with 20.7 °C. This corresponds to a cooling of 4.2 to 6.0 °C in Azores and 5.1 to 5.9 °C in Madeira.
The humidity of the air depends to a large extent on the air temperature. The warmer the air, the more water it can absorb. At a temperature of 25°C it is 23 grams per cubic meter, at 30 degrees it is already 26 grams. Therefore, the air humidity is given as a relative value to the temperature-dependent maximum amount. It becomes unpleasant when high humidity is combined with high temperatures.
Humidex is an approximate, sensed temperature calculated on the basis of air temperature, dew point and humidity. It was developed in 1965 by the Canadian meteorologists J. M. Masterton and F. A. Richardson. Since the wind speed is ignored here, it is not very meaningful in areas below approx. 15°C. Above that, it is more reliable, since at higher temperatures humidity plays a greater role than wind.
Rainy days per month
By definition, a rainy day is a day on which at least 0.1 liters of precipitation per m² fall. This corresponds to a 1 square meter puddle in which the water stands 0.1 mm high - insofar as the water does not seep away or evaporate. So it does not have to rain all day long. December brings the most rainy days (13.7) in Azores. With an average of only 5.6 days, August is the friendliest. In Madeira, it rains most often in November with 8.5 days.
Precipitation amount per day
Depending on the season and the location of a country, the wind brings with it a varying amount of water. As a rule, the water evaporating in the oceans is absorbed and then transported inland. The greatest amount of rain (hail or dew are also forms of precipitation) in Azores occurs in December. Then about 4.7 liters per square meter fall per day. In Madeira, the average amount of precipitation ranges from 0.1 liters per day in July to 2.7 in November. However, these are average values. If you consider that there are only 13.7 rainy days in Azores in December, each of them accounts for about 10.4 liters.
Sunshine hours per day
With 2373 hours of sunshine per year, Madeira is in the lead. The most hours of sunshine (8.0 per day) are in August. Azores falls into second place with only 1935 hours. There the sun is visible in December even only 3.0 hours per day, so not hidden behind clouds.
Hours of daylight
The length of a day varies throughout the year and depends on the distance from the equator. The length of day measured here is the period between the middle of the morning and evening twilight. In December, the day in Azores is only 10.0 hours long. In June, on the other hand, it is 15.3 hours. In Madeira, it is 10.5 hours in December and 14.7 in June.
