The Azores (Açores) are a chain of nine volcanic islands scattered across the mid-Atlantic, roughly 1,400 km west of mainland Portugal. Known for crater lakes, dramatic sea cliffs, thermal springs, and green pastureland, the archipelago offers whale watching, hiking, and diving in a landscape often compared to Ireland and Hawaii combined. Ponta Delgada, on São Miguel, is the archipelago's largest city and main gateway.
The Azores have a mild, humid, oceanic (maritime subtropical) climate moderated year-round by the surrounding Atlantic and the Gulf Stream. Temperatures are remarkably stable across the year, rarely dropping below 12°C in winter or rising above 26°C in summer. Mist, cloud, and light rain are possible in any month, and weather can shift within hours, particularly at higher elevations like Pico Mountain and Sete Cidades. Warmest months are July through September, around 22-25°C, while the coolest months, January and February, average around 14-15°C. Rainfall is spread throughout the year with no fully dry season, though summer months are noticeably drier and sunnier than autumn and winter.
