The UV index will be moderate at this time of year, so not something to worry about for the average person.

Best sunset cruise in Lisbon? Try FRS PortugalAll the great cities in the world are often defined by a river. Take London, Paris, Bangkok or Kolkata, all these cities have a pulse of life and an element of grandeur thanks to the river running through them. Of all the cities that have a river running through them, Lisbon is probably my favourite city. I remember the first time coming to Lisbon 12 years ago and on the first morning I woke up for a walk and meandered my way through the city....

The last time I saw LisbonIt has been almost a year since I last saw Lisbon. I arrive on a wet, miserably cold evening that is typical for January in the city. Our taxi can’t find our hostel but drops us off close enough. A short walk, in the horizontal rain , feels like an eternity, each drop of water scoring our skin like a razorblade. ...

Where to drink craft beer in Lisbon, PortugalThere isn’t much better than sitting down for a cold pint after a few days of touristing. Resting aching feet, removing the hefty backpack, looking through photos of the day, and swapping highlights becomes a holiday ritual when there’s a glass of something refreshing to go with it. The only drink I wanted to seek out in Lisbon was vinho verde, the tart cousin of white wine, however, we all know beer is my poison of choice, and the Portuguese capital has not just a great number of craft...

The best places to eat in Lisbon, PortugalYou could easily survive four solid days in Lisbon on pastéis de nata and vinho verde – the iconic custard tarts and the sharp ‘green’ wine are everywhere in the Portuguese capital, and are well worth the indulgence.

But Lisbon’s food scene is vibrant yet still traditional at its heart; very much flourishing and I completely underestimated it....
