The month of July was up to the 18th which had the average value of the lowest maximum air temperature of the last 30 years.
"It is verified that the average value of the maximum temperature of the air in the period 01 July 18 shows a deviation from the normal monthly value of -1.6 ° C [graus Celsius] is up to As of July 18 the lowest value of the last 30 years, "according to information made available to the Lusa agency by the Portuguese Institute (19659003) For example, July 12, 14 and 15 The maximum temperatures in the southern regions were four degrees Celsius lower than normal As early as the first 13 days of June, maximum temperature values were below normal throughout the territory. However, there was a warm period between the 15th and the 25th of June – a period when a heat wave occurred in the northern region and in some central locations – and a normal period between the 26th and the 25th of June. June 30.
In June and the first half of July, the meteorological situation in Portugal was "determined by one or more anticyclonic nuclei located in the Atlantic, whose action was felt from the northeastern region of the Azores". , to Scandinavia, while the Iberian Peninsula was under the influence of depressions, with the expression at altitude, and by the passage of frontal surfaces of low activity ", according to the scientific explanation of the IPMA
At the Lusa, IPMA meteorologist Sandra Correia explained that the positioning of the Azores anticyclone is decisive for the weather conditions in Portugal. This anticyclone, whose mean position is in the region of the Azores archipelago, usually moves northeast in the summer and further south in the winter, according to the IPMA.
According to the predictions made on this date, the
IPMA, in its monthly forecast updated Thursday, indicates that next week – from 23 to 29 July – there are indications of lower rainfall to normal and also below-normal temperatures
The following week, from July 30 to August 5, the scenario is similar, with the possibility of fog or low cloudiness near the western coastal band, and which may also be formed in the other regions of the territory
With regard to the quarterly forecast, updated Monday, the joint analysis of several models made by the IPMA, the forecast for the month of d 39; August is "precipitation in southern parts of the interior (-0.5 to -0.25 ° C).
For September, one of the mathematical models based on which the IPMA makes its predictions do not indicate any Guidance as to whether it's going to rain more or less or if the temperature will increase or decrease, however, another model has a lower than normal temperature indication in the southern region.
Meteorologist Sandra Correia points out that "the monthly forecast corresponds to a product in the development phase and presents scenarios in probabilistic terms, and its use must be made with reservations."
