II.4.2. Climate
The Mediterranean city belongs to the humid and sub-humid bioclimatic domains, its climate
is mild and temperate at the coastal level and cold at the inside as shown in (figure 4).The wet
floor covers the western mountainous area as well as the summits to the east and south. The
sub-humid domain prevails over the 4/5th of the territory of the state with rainfall between 1000
and 1500 mm/year. Under the influence of the sea, temperatures are mild in winter (11°C in
January) and warm in summer (24°C in August) on the coast where thermal amplitudes are low.
They are milder in winter (9°C) and warmer in summer (27°C) in the interior where the
amplitudes are more pronounced.
Figure 4: Climate of Skikdain 2022 (https://weatherspark.com/y/53041/Average-Weather-inSkikda-Algeria-Year-Round).
The relative humidity in Skikda province reaches a significantly high level, averaging at 65.5%
and ranging between a minimum of 68.91% and a maximum of 75.34% (figure 5). The presence
of the sea plays a crucial role in maintaining such elevated humidity during the summer season,
effectively reducing the duration of dry spells in the summer (O.N.M., 2012).
The coastal region of Skikda province is particularly prone to strong and destructive winds,
with speeds reaching up to 130 km/h. These winds cause extensive damage along both the coast
and inland areas. The prevailing wind direction predominantly ranges from southwest to
southeast (Touati et al., 2004).
