(data from Meteorological Office)

    
Short-term weather records for Wainfleet, Lincolnshire, UK, for the period 10 July to 10 August 2004: (left) daily
rainfall; (right) daily sunshine hours (data from Meteorological Office)

distribution of tides exceeding 10 cm increments of elevation. Data from PSMSL and NTSLF


Observed (black) and predicted (red) tidal levels recorded at Lowestoft during the passage
of a storm surge between 30 October and 2 November 2006. Although the maximum tidal
height was not exceptional, the tide hardly retreated, so that water levels were constantly
above the predicted level of high tide for approximately 20 hours

situated c. 40 km south-east of Orford Ness, Suffolk,        48 km east of Southwold, Suffolk, for the period 
with data recorded between 2002 and 2007 (data             1986-1999. Calculated from the Meteorological
from CEEFAS)                                                                 Office European Waters Wave Model
