National Tidal and Sea Level Facility
The
National Tidal and Sea Level Facility
(NTSLF) is the UK’s centre of excellence for sea level monitoring, coastal flood forecasting, and the analysis of sea level extremes. It is the focus for sea level research and for its interpretation into advice for policy makers, planners and coastal engineers.
Tides and storm surges
Tides
are the predictable rise and fall of the sea surface as the Earth rotates while the moon’s gravity, as well as the sun’s, pulls on the oceans.
Read about tides
Storm surges
are caused by the weather, especially low pressure systems (inverse barometer effect), strong winds and the Earth’s rotation (forcing water towards the coast). Surges are in addition to tides, and computer models can forecast their combined levels alongside weather forecasts.

Latest news
UK Met Office has adapted NEMO as the Operational Storm Surge Forecast Model.
NTSLF will display these outputs
from April 2020.
The highest tides in 18.6 years occurred during 19–30 September 2015 due to the
moon’s nodal cycle
(video).

storm surges
in December 2013–January 2014.
