The Canary Islands use Greenwich Mean Time (GMT). This means the time zone is exactly the same as the UK while mainland Spain and other European countries are one hour ahead.
Spring officially begins in March meaning the clocks go forward by one hour for daylight saving time. They then go back one hour in late October.
Spain-Tenerife recommends that you do not drink water from the tap or public fountains in Tenerife. Canarians usually drink bottled water and we advise you do the same, large bottles and water containers are available throughout Tenerife.
Most of Tenerife drinking tap water comes from desalinated sea water and doesn’t have a good taste, it’s fine for bathing or washing clothes, etc.
For drinking, tea, coffee or ice always use bottled water.
Some people experience upset tummies and other digestive problems that possibly are caused by the tap water.
For long term tourists or residents we recommend that you install a reverse osmosis water filtration system with a mineral cartridge that puts back a balanced PH and mineral concentration to the filtered water.
