The climate in a few words

Spain has four climates overall the country.

Mediterranean climate is marked by Leveche winds: hot, dry, easterly or southeasterly air currents that originate over North Africa. This usually happens in spring.

A cooler easterly wind, the Levante, funnels between the Sistema Penibetico and the Atlas Mountains of North Africa. These easterly winds are the ones which most influence the Mediterranean climate, for they are mild in temperature and humid.

The inland areas of the Iberian Peninsula, on the Central Plateau, have a continental climate. The summers are very hot. There are very low temperatures in winter, with −15 °C (5 °F). Although it rarely rains during summer, there is often heavy rainfall in spring and autumn.

Northern Atlantic coast

An oceanic climate prevails from the Pyrenees to the Asturias, area which incorporating Galicia is sometimes called "Green Spain", characterised by relatively mild winters and warm summers. Temperatures vary only slightly, both on a diurnal and a seasonal basis, and averages range from 9 °C (48.2 °F) in January to 21 °C (69.8 °F) in July. The moderating effects of the sea are less prominent further inland, where temperatures are more extreme than those on the coast. Distance from the Atlantic Ocean also has an effect on precipitation levels, so there is less rainfall in the east than in the west. Autumn (October to December) is the wettest season, while July is the driest month.

The Canary Islands

The Canary Islands have a subtropical climate in terms of temperature, this being mild and stable (18 to 24 °C or 64 to 75 °F) throughout the year. In terms of precipitation, the eastern islands are semiarid while the westernmost ones receive more rainfall, with some very wet areas in the mountains of La Gomera and La Palma, home to the cloud forest known as laurisilva.

The Medditerrenean climate is also good for asthmatics, as it is warm and moist. I have a relative who has been living in Spain for quite a long time now, and she hasn't had any difficulties in breathing there. So ASTHMATICS, Medditerrenean climate can be a very good choice towards the recovery of your health :)
