The Canary Islands use the 24-hr clock as opposed to 12 hours, using am and pm.
Greenwich Mean Time (GMT/UTC) is maintained in Lanzarote during the winter, which is the same as the UK, while mainland Spain and many other European countries are 1 hour ahead of the Canaries.
Clocks also go back 1 hour during late October and go forward 1 hour in March.
Spain-Lanzarote recommends you avoid tap water and buy bottled mineral water instead. Please do not drink from public fountains or public spouts.
Water availability is obviously low, a consequence of rain absence. Few water sources exist in the Risco de Famara (Famara Massif) region and in the centre of the island. The supply, however, is insignificant in comparison to the quantities needed. Undoubtedly the most important source of potable water is desalination of seawater. It is estimated that tourists use 1.67 times more water than residents.
Some hotels try to be as environmentally friendly as possible and conserve water by washing towels every other day.
