6. Oceanographic Conditions in Summer 2024
The BSH produces and provides a comprehensive weekly analysis of sea surface tempera-
tures (see https://www.bsh.de/EN/DATA/Climate-and-Sea/Sea_temperatures/Sea_sur-
face_temperatures/sea_surface_temperatures_node.html). This approach combines all meas-
urements collected from time series stations and ships with satellite data and uses statistical
methods and spatial interpolation to generate a comprehensive data set. This contains esti-
mates for the weekly mean values of sea surface temperature as a raster data set with a spatial
resolution (pixel size) of 20 km x 20 km.
Figure 6.1. Spatial distribution of sea surface temperature (SST) anomalies for the summer of 2024
(June, July and August). Anomalies are shown relative to a climatological mean SST field comprising
the summers of the years 1997-2021, i.e. 25 years. Source: BSH.
Information from this blended analysis SST analysis for the summer months of 2024 (June,
July and August) reveals a region of pronounced warming in the southern North Sea, basically
in the English Channel and along the West and East Frisian coasts. A further warming pattern
stretches off western Norway along the Norwegian Trench (Figure 6.1). In these regions the
SST was about 0.5°C to 1.0°C warmer than the 1997-2021 climatological summer mean. The
coolest region with SST anomalies of about -0.5°C was observed off eastern UK, with a cool
center located at about 56°N/1°30’W.
A respective ranking map (Figure 6.2) demonstrates that the southern English Channel and
the waters of the West and East Frisian Coasts Sea succumbed to one of the three warmest
