"Pleasingly warm weather for the time of year," not for much longer as rain is predicted for the Algarve on Tuesday, followed by a steady fall in temperatures, bottoming out with a nighttime low of just 9°C on Saturday night/Sunday morning.
The Algarve is due to escape the worst of a blast of polar air heading south over the next few days, bringing freezing temperatures to high ground in central and northern Portugal and snow predicted for the Serra da Estrela.
