if you look 12 04.........into the film ...there is a indication where the weather was took from...and it is not faro

could be taken on the moon you say .....there is info where it was took Lagos/Luz ....if you don't want to believe it fine ...have you anything ....to disprove it ...or to prove it not true
apart from the moon that is .... 
Sorry, I can't find any independent confirmation of where that weather chart was supposed to have been located.
Here are the reasons why I'm questioning this.
1. Sagres versus Faro:Sagres is on the (exposed) western tip of the Algarve and Faro is 2/3 to the east towards Spain. PdL is in a little cove around 10-12 km from Sagres, whereas it is around 40 km to the west of Faro.
If you look at satellite images, the Atlantic weather fronts cross broadly from west to east at this time of year at least, sometimes from a slightly more northerly direction, sometimes from a more southerly one.
2. Kate's description supposedly 'doesn't match' "last photo":On the alleged point that Kate had said that the day was cool and wished she'd taken a cardigan for Madeleine - yes, you can sit in a sheltered spot in spring or autumn and feel warm, then walk in a shaded area and feel a cold breeze.
3. Back to that weather chart. It has NO visible specified location or source. It could literally have come from anywhere. The snapshots are identical to those on Havern's forum, but AFAIK, there is still no source attributed to the chart itself.
OK, I'll set that aside for the moment.
4. Onto the "analysis" in that video:Cloud cover versus temperature:"On the Thursday there was about 50% cloud cover from dawn, rising to nearly 100% cloud cover by the early afternoon." @10:15-40 ish.
The vertical lines in that chart separate the days. The high cloud cover in that chart is towards the right-hand side of that 24-hour period, therefore it can't represent early afternoon - it's latish evening. That chart shows the maximum temperature as 19, and right above the high cloud cover. That might seem odd, but it would be consistent with cloud cover sealing in the day's progressive warmth.
Then...
"... The temperature chart shows us that the temperature on Thursday rose from a cool 13 degrees C (55 degrees Fahrenheit) in the morning, to just 17 degrees C (63 degrees Fahrenheit) around mid-day, when the photo was supposed to have been taken." So... let's stop there for a minute. If the time of the cloud cover is meant to correspond vertically to the time of the temperature, the cloud cover was only 50% when the temperature was around 17°C "around mid-day".
I have already posted a link to a Sagres weather chart for that day showing that there were approximately 11.5 hours of sunshine that day. I'll add it here, when I find it again.
Wind direction:Then, have a look at the wind direction on that chart. It started off as coming from the West and moves to WSW during the day, and very late evening /overnight drops to WNS, which is consistent with Faro.

Note:
Beaufort scale:
4 Moderate breeze 20–28 km/h. Small waves with breaking crests. Fairly frequent whitecaps. Dust and loose paper raised. Small branches begin to move.
https://en.wikipedia.org/wiki/Beaufort_scaleAlthough there can be variations even a few kms away, the Sagres charts coincide far more closely to the weather in the "last photo" in PdL than to Faro.
Moving on...
5. Photos depicting Algarve weather:"One well-respected Madeleine McCann researcher, a retired former police superintendant, has collected dated photographs to show exactly how the weather changed on the Monday of that week..."Fine, but the photos (aside from one which is apparently from "near Lagos" during the sunny previous weekend), don't state
where the ones taken later in the week were taken. The one that supposedly illustrates 3 May appears to be inland... somewhere.
6: Local former RAF ex-pat diary:Then, the narration moves on to an ...
"... ex-RAF man, now an ex-pat living in Praia da Luz, kept daily weather records. His diary confirms the cloudier, windy, cooler conditions that prevailed on that Thursday, when the last photo was supposed to have been taken." (up to @13:30 ish).
Hmm.
I can find no indication that this ex-pat was examining a PdL weather chart (as the source chart for Hall's video comes from Havern's, with no original source).
There is, however, an extract from his alleged diary (for which I can find no online source either that doesn't originate from... Havern's, yet again).
So, let's see.
The only trace that I can find is of a former UK police officer quoting the ex-pat RAF chap as saying, supposedly concerning the evening of 3 May (although as the source hasn't been provided, that's not clear either):
"I arrived at my apartment about 1145pm. It was a clear dry moonlit night and no sound of human or vehicular activity, and it was good to reflect that better weather had now set in."Where was he during that day? Where was this apartment? In PdL or somewehere else? Did he seriously arrive back in PdL on 3 May at around 1145pm to "no sound of human or vehicular activity" just as the whole of PdL was out and about searching for a missing child ??
This also appears to have been attributed to this former RAF ex-pat:
However of much greater import - is the wind speed and cloud factor.
At 1400 on 3 May, wind speed is recorded as force 4 with a still air temperature of 17 C. Although the pool area is to some extent sheltered, with the westerly direction component the wind would be markedly chilly with a chill factor pulling the temp down to as low as 15C - definitely not suitable for scantily clad pool activity.
That description corresponds more to Faro, as opposed to Sagres.
From a different thread, the alleged former UK policeman answers, in response to a question about weather data from Faro:
"Yes, I know it is Faro airport, but that is only a few km up the road."No, it's not, it's 40 km to the east.
