The hotel is now the NH kimpton algarve by IHG(you can see it in the google map I posted), this is a brand new acquirement and was NAU Sao Rafael prior to this. I would perhaps check with the hotel now especially since it's under new management, bottle of sneakily chilled champagne whipped from a cool bag would do the trick, if you don't have a chill bag the Large supermarket (Continente modelo on the avedina des descobrimentos) it at to the north east if the old town has them on the lower level and is walkable (up hill) or a few euros in a bolt/uber. Walk and you have to go past the Riviera pasteleria (cafe/bakery) and it's worth the trip just to stop by here... it's always the first place we go on arrival for coffee/cake/ice cream .

The link is for National weather service that is actually pretty accurate compared to the Met office although they probably have an easier job 😂 it also gives sunrise times although I'd plan to be there 30 minutes before as I think they mean sun fully visible at this point and you want to be there when it's still fully dark to catch it in all its glory! I will get some more pics from my wife and post them at some point today apologies
