A Climate for Change

by a maximum of 1°C (winter, summer and autumn),
while spring temperatures will remain the same. No
significant differences in precipitation are expected in
most regions (with a maximum change of -2.5% along
the coast in autumn). It is important to note that these
are projections for a scenario of relatively low emis-
sions growth and are only forecast until 2025.
2041-2070
In estimating the likely climate change for Croatia from
the period 2041-2070, the Meteorological and Hydrolog-
ical Service of Croatia (DHMZ) predictions are presented
in Table 3-1. Maps that indicate these changes are includ-
ed in Figure 3-2, Figure 3-3, Figure 3-4, and Figure 3-5: II
II Branković, Patarčić, and Srnec 2008. The results are derived from the three-member ensemble integrations of the global EH5OM model,
from the Max-Planck Institute for Meteorology, Hamburg, Germany. The horizontal resolution is approximately 200 km. The period 1961-
1990 (the “present” climate) and the period 2041-2070 (the future climate) under the IPCC A2 scenario are analysed and compared.

Season Impacts and Changes Notes
Winter - Northern Croatia will experience a warming
of 2.5°C while the rest of Croatia will warm by
between 2° and 2.5°C.



  • This will be more important for inland rather
    than coastal Croatia.

    • Winter is the only season which does not
      show a difference in precipitation, though
      there may be a slight increase in the north
      and a slight decrease in the south.

    • Surface snow in northern Croatia will be-
      come uncertain. Snow is important for soil
      moisture - affecting the availability of soil
      moisture required for the subsequent grow-
      ing season.
      Spring - Croatia will be 1.5°C warmer throughout the
      country and at sea.



  • A slight drying trend is expected in southern
    and western Croatia during spring (-0.1 mm per
    day – which means 9 mm less for the season).

    • A statistically significant reduction in soil
      moisture in the spring (March, April and
      May) is expected throughout Croatia. In ad-
      dition, inter-annual variation in soil moisture
      will increase.




Summer - Temperatures will increase by 3.5°C in the north-
ern Adriatic and in other parts the temperature
will increase between 3° and 3.5°C.


  • During summer, there will be 9 mm less rain per
    month in the east (27 mm for the season). This
    represents a more than 10% drop. In the rest of
    the country, there will be a drop of 0.2 mm/day
    in precipitation (18 mm less for the season).

    • There will probably be more heat waves.III

    • These expected changes in temperature will
      be similar for all years

    • This model predicts a reduction in the sum-
      mer convective precipitation (downpours)
      over many parts of Croatia; this amounts to
      about one third to one half of the reduction
      in total precipitation.




Autumn - Temperatures will increase by 2.5°C mostly
uniformly throughout Croatia.


  • Precipitation levels will drop 27 mm for the sea-
    son in the south on the coast, Moving northward
    along the coast, the reduction will be 18 mm for
    the season

  • In the northern part of the country (including
    Istria and most of the eastern part of Croatia) the
    reductions will be 9 mm for the season
