Check the live forecast above for your exact location, but for a broad view, Portugal’s weather over the next ten days will be dominated by high pressure, bringing settled, sunny conditions to most regions, though the far north may see a brief spell of cloudier, cooler weather mid-week.
What is the general outlook for Portugal over the next ten days?
The Azores high is firmly in charge, meaning the Algarve, Lisbon and the Alentejo can expect plenty of sunshine with daytime highs reaching the low 20s Celsius. The north, around Porto and the Minho, will start bright but a weak Atlantic front could bring thicker cloud and a few light showers around day five or six, before clearing again. Coastal breezes will keep temperatures comfortable, while inland areas, particularly the Alentejo, will feel a few degrees warmer.
How does the forecast compare for the Algarve and the Lisbon coast?
The Algarve, including Albufeira, will see the most reliable sunshine, with sea temperatures still pleasant for late-season swimming. Lisbon will be similar but with a slightly stronger northerly wind, especially in the afternoons. For those checking a 10 day weather forecast UK before travelling, expect Portugal to be significantly warmer and drier than the UK over the same period.
Will it be warm enough to swim in the Algarve?
Yes, sea temperatures around Albufeira and the southern coast are around 19°C, which many find comfortable for swimming, especially in sheltered bays. Air temperatures in the low 20s make for pleasant beach conditions.
Is the 14-day forecast for Portugal reliable?
A 14-day forecast gives a good indication of the general weather pattern, but day-to-day accuracy drops after about seven days. For a UK weather hub comparison, the Met Office outlook for Portugal is reliable for the first week.
What about the weather in northern Portugal?
Porto and the Douro Valley will see more cloud than the south, with a chance of light rain around day five. Temperatures will be cooler, around 18-20°C, but still pleasant for exploring the cities and wine regions.
