Weather Overview for Cork
Cork is Ireland’s
second largest city, located on the River Lee on the southern Irish coast. Its
name is derived from the Irish word ‘corcach’, meaning ‘marshy place'.
rarely experiences any extremes of temperature; it seldom falls below freezing
or rises above the low 20s. It does however, experience high relative humidity.
Humidity ranges between 78% and 90% all year round, with October and November
measuring the highest percentages; this often leads to the development of fog
which enshrouds the city about 100 days each year. While some complain of the
frequent fog and rain, and the mild temperatures, it should be remembered that
it is these conditions that give Ireland its famed green landscape. Cork is also one of the sunniest cities in Ireland – but
don’t get too excited: this means a whopping 6 hours of sunshine per day in the
clearest months of May and June, and a mere 69 days of no recordable sunshine
per year. That’s right: 69 whole days of completely impenetrable grey. Jumping
for joy yet?
March till May, is pretty chilly with moderate rainfall. The average high
temperature rises gradually from 9°C in March to 14°C in May, with night
time lows only just averaging above 5°C in March. However, the clouds go on
retreat and the sun comes out for longer and longer each month, increasing to 4
hours per day in March, 5 in April and 6 in May. March is a particularly busy month, encompassing Gaelic Week and
Saint Patrick’s Day.
June till September, is kept mild by westerly winds coming in from the Atlantic; but this is still the most pleasant season to
visit. Rainfall is at its lowest, temperatures at their highest and the sun
comes out for the longest. The average high temperature peaks at 18°C in July and August, sitting at slightly pathetic 17°C and 16°C in June and September.
It can get into the low 20s in July and August on particularly sunny days.
Night time temperatures hover around 10°C throughout the season which is
definitely cool enough for a jumper and a jacket. From the end of June,
sunshine levels start to decrease again and by September only 4 hours per day
can be expected on average, though this is often shared out amongst rainy, grey
days and whole days of clear skies. July is probably the best time to visit as
it is the warmest and driest month. Even then swimming in the sea can be left
to those with bravery, or simply bravado.
October and November, is very cool, grey and often the foggiest time of year.
The average high temperature falls quickly to 13°C in October and 10°C in
November, with night time lows falling below 10°C in October and below 5°C in
November. Rain and cloud muscle-in, leaving a measly 3 hours of sunshine in
October and only 2 in November.
December till February, is cold though not bitterly so, wet and rather gloomy. January and February are the coldest, both
experiencing an average high of 8°C and an average low of 3°C. Rainfall is at
its highest of the year in December and January, falling on most days in a
dismal drizzle. It rarely gets down to freezing and snow is very rare though
frosts are not uncommon away from the coast. The sun continues to come out for
only 2 hours per day.
Cork’s climate is similar to
the rest of Ireland and the United Kingdom;
it has a maritime climate characterised
by mild and moist conditions and a narrow temperature range. The climate in Cork is affected by the North Atlantic Current which is the strong ocean current that
brings the Gulf Stream up from Mexico
through to the west coast of Ireland
and the UK.
The Gulf transports
enough heat to satisfy the world’s energy demand a hundred times. It is this
phenomenon that keeps the southwest coast of Ireland,
a few degrees warmer than the east coast and the north.
