Costa I am also very curious about areas next to Amareleja means.I think someone in the past had posted some really interesting figures.Can u help?Which is the warmest area for JJA for Portugal do u think?
Maybe it was me who posted it? Or JS? If it´s Herdade dos Lameirões, locally, that´s not that warm ( it´s placed in the plains area, not in the warmer lowlands). Though it´s figures sometimes can be interesting, but not more than that.
Unfortunately there´s no detailed data about the exact figures for the warmest areas during JJA for Portugal. Not even near. Costa´s point was stating exactly this.
But in some warm areas ( not the warmest) and nearby there are some Spanish weather stations that gives interesting values ( from Northeast Douro, until the Southeast Guadiana).
For example, close to the Tagus valley, but further north and at higher altitude, climatological averages for the warmest month can be as high as 38ºc or a little more... How accurate is this value? Anyone knows?
I only know that the Tagus Valley, before the Alcantara big water body, reaches extremely high values, due to the IM article published in 2002 regarding the warmest areas in Portugal in JJA and because of the geographical features on the zone. If you want, I can place the maps here ( just for higher probabilities conclusions).
Though to confirm this at 100%, some weather measurings should be done in these areas.
These places have much more conditions, in my opinion, to get high averages, than any Amareleja or Herdade dos Lameirões. They are much more protected from weather variations. If we talk about Douro, this is even more evident. As you can see on the map that Costa posted, in the Douro area, you get places at very low altitude well inland and sheltered by several mountains groups. This explains it´s very low annual precipitation levels and high temperatures during the summer. I have been receiving some ocasional data from the Sabor ( because of fieldwork) and the values are pretty high, according to the season and more importantly, even when the country, presumably isn´t in a very warm period.
The Guadiana, has also nice warm places, but I´m not so sure about being the warmest in Portugal. This is due to the fact, that seems to be less sheltered than all the others, though this needs confirmation.
But it´s surely well warmer than Amareleja or Lameirões, at least, in some good extensions.
So we can identifly, at least, 3 major very warm areas during the summer ( Douro, Tagus and Guadiana valleys) and also a possible fourth region, that´s located in the Algarve, but inland, that´s called barrocal.
But this last one, has less chances than the other 3, I think.
Let´s remember that sometimes we see a discrepancy between the warmest places on average and the ones which get the temperature records.
But even having this in mind, I doubt that the Amareleja is the place that has more conditions to get records. One thing is sure, Portugal has very scanty data... lol
