Rainfall is more frequent during this period, and while sunshine is still prevalent, it’s interspersed with cloudy days. Sea temperatures average around 17C (63F), generally too cool for swimming for most people.
Understanding the climatic conditions of the Algarve in January is vital for planning activities and packing appropriately. This period offers a tranquil escape from harsher northern European winters, attracting visitors seeking outdoor pursuits like hiking, golfing, and exploring the region’s natural beauty. Historically, the Algarve’s mild winter climate has made it a desirable destination, contributing significantly to the development of its tourism industry. The lower visitor numbers during this season offer a more relaxed pace compared to the bustling summer months.
