Iberian's climate maps (warm, records, temperatures, rainfall)

[overdrive1979]

Here are some climate average maps, which they are based in nationals weather services.

Koppen climate classification:




Average yearly rainfall, (mm):





Average temperature in january, (º C):





Average temperature in July, (º C):





Average number of yearly sunny clear days, (I can't find the same for Portugal):






Average yearly of number of days with precipitation equal to or above 0.1 mm:





Average yearly number of days with thunderstorm:

Here you can see a better wiew of Koppen map for Iberian peninsula:

Continentality index of Rivas and Martinez:
10(T+m+M)

Where "M" mean average high temperatures of coldest month.
Where "m" mean average low temperatures of coldest month.
Where "T" mean average yearly temperature.






It just make more sense with the geographical map of Iberian peninsula:

Three months ago I made myself a map who shows how different rainfall pattern are across Iberian peninsula and its surrounding areas throughout the year:

There is another one that I made myself, that shows the average number of dry months per year, also it shows what is the dry month with different colours.

The sources are the same than the other map I posted before.

In the preparatory work, I agreed with some friends of me on Spanish weather forums "Meteored" to according the scale used for mesured the lack of rain in warm and cool months.
So, we agreed that dry months between April and October mean less precipitation than 40 mm, and less than 20 mm for the rest of the year, basing on the different evaporation exerced by the strong sunshine in warm months on the land.
For instance, if 25 mm of rain fall one day in December, and the rest of the month remains overcast/foggy and dry, the ground remain humid, as evaporation of moisture is even almost negligible during these coldest months.

The different colours show what is the dry month:
Red: July, which appears everywhere as the most common type.
Light green: August, which is the second most common type in the Iberian peninsula.
Dark blue: February, which is common in the eastern Pyreenes an rare in the Sistema Iberico mountain ranges
Dark green: January, which is rare in the eastern Pyrenees and in the Sistema Iberico mountain ranges .
Black: March, which is very rare, only appears near to the Catalonia's coast in the Sistema Iberico mountain ranges and in southern plains of France.
Blue-green; June, which is very rare, only appears in the western Canary islands.

Asterisk, it means that the driest month of the year happens in winter, and there are also some summer months having less precipitation than 40 mm.

Unerlined, it means that the driest month of the year happens in winter, but it has more precipitation than 20 mm. There is also some summer months having less precipitation than 40 mm.

Negative sign, it means oceanic climates being very constant in rainfall throughout the year, so the difference between the maximum and minimum values is lower than 40 mm.

The number ten given in brackets located in southeastern part of Spain means there is really ten dry months, and not two separate figures.




It would make more sense to compare them to the physical map of Iberian peninsula I posted before, just three months ago.

Wow, nice work, I'm going to analyze it now.
What's that 10 location?

It's between Albacete and Murcia.

Any holes are not filled in within previous sources of France and Portugal, so I decided the use to the last source, as I was trying to find climate averages for some cities for refilling these holes:

Good job on the maps!

After studying this I notice that Vigo Spain is surprisingly close to my dream climate. The level of sunshine and the winter temps are nearly exact. The amount of rain is quite close to. The only thing is is that the summer temps are about 6ºC too cold.

Try Braga, Portugal, or Ourense, Spain.
The summers are definitely hotter in those towns.

Thanks! The only thing about these cities are that they are too dry thought Braga isn't nearly as dry as Ourense. With me I prefer to live in a rainforest.
