Useful information
 Necessary equipment Binoculars Nearly indispensable for all birdwatchers. There are many models and brands for sale but we recommend those with magnification between 8 and 10x and lens diameter between 30 and 50mm. Spotting scope Although not essential, a spotting scope will allow you to observe details that would be hard to spot with binoculars and also allows for more distant observations, which avoid disturbing the birds. They provide precious help in identifying species. Field guide The use of a field guide is essential to any birdwatcher. When choosing one, take into consideration the quality of the illustrations, the quality of text and distribution maps, its size, flexibility and ease of handling, resistance and price. Notebook A field notebook is very useful to record the observed details. Information such as the surrounding environment, climatic conditions, a list of observed species may be recorded for later use. Suitable clothing Finally, clothes should be comfortable and inconspicuous. Shoes, in particular, should be comfortable and hardy. You can find all these items available in our online store |
 Climate Mainland Portugal The climate in Portugal varies considerably from one region to another and is influenced by the altitute, latitude and proximity to the sea, which offers mild winters, especially in the Algarve. In the Porto and Norte area and Beiras region, particularly inland, nearer Spain, the winters are colder, although the temperatures are still mild when compared to the rest of Europe. There is some snowfall. It occurs most in the Serra da Estrela mountains, where we find the highest point in mainland Portugal (1,991 m) and where it is sometimes possible to ski. The summers are hot and dry, especially in the inland areas (Trás-os-Montes in north-eastern Portugal and Alentejo). Temperatures are slightly lower in the coastal areas, because of the influence of the sea. There are often warm, sunny days in autumn. Azores The climate in the Azores is influenced by the islands’ latitude and by the Gulf Stream, and temperatures are mild there all year round. The same factors also influence the sea temperature, which is very pleasant both in winter and summer and ideal for nautical sports all year round. Madeira The subtropical characteristics of the weather in the Madeira Archipelago can be explained by its geographical position and mountainous relief. The climate in Madeira is exceptionally mild, with average temperatures varying between 24 ºC in summer and 19 ºC in winter. The sea temperature is also very pleasant all year round, thanks to the influence of the warm Gulf Stream. It varies between 18 ºC in winter and 22 ºC in summer.
