According to the Portuguese Institute of the Sea and Atmosphere (IPMA), the average air temperature stood at 9.5 °C last month, the fifth highest value since 2000.
The daily values of maximum temperature were almost always higher than the average monthly value, with emphasis on the periods between the 1st to 3rd and 27th to 31st of January, in which deviations of more than 4 °C were recorded.

As for precipitation, last month was the sixth driest in 90 years and the second worst since 2000, surpassed only by January 2005.
The IPMA report adds that the average amount of precipitation was much lower than normally recorded between 1971 and 2000, corresponding to only 12%.
“There was a very significant worsening of the meteorological drought situation, with an increase in area and intensity, with the entire territory in drought at the end of the month with 1% in mild drought, 54% in moderate drought, 34% in severe drought and 11% in extreme drought”, says the institute.
Regarding the percentage of water in the soil, there was a significant decrease compared to the end of December, and the IPMA highlights values below 20% in the Northeast and South regions.
