The year 2010 was the hottest by a large margin since records began being kept
in Israel, with temperatures two to three degrees hotter than the average,
according to the Israel Meteorological Service’s year-end summary.
more, temperatures were one to one-and-a-half degrees Celsius higher than the
next hottest year, a striking statistic, according to the IMS. Most years, the
average temperatures fall within 0.1- .0.3 degrees of other years.
example, the average temperature for Jerusalem between 1981 and 2000 was 17.5
degrees. In 2010, the average temperature was 20.3 and during the next hottest
year, 1998, it was 18.7.
Similarly, the average in Beit Dagan, where the
IMS is based, is 19.4 degrees. In 2010, the average was 22.1 degrees and the
next hottest year was 20.9 degrees.
Every month of the year was hotter
than average, the IMS said.
The IMS continually tracks and predicts the
weather using a series of monitoring stations around the country.
higher temperatures and decreased precipitation are among the predictions of
climatologists for the next century, it would be hard to prove that a single
year was the result of climate change.
Climatologists are looking for
trends in 30 year periods over hundreds of years.
The IMS also tracks
rainfall, and while this past year was one of the driest, there have been drier
However, 2010 was unique in that it had the least amount of days
of rain at many of the monitoring stations. For example, in Jerusalem and Haifa,
the fewest number of rain days were recorded in the past 80 years.
hydrological year is usually calculated based on the rainy months – meaning the
year is comprised of part of 2010 and 2011, but the IMS conducted its
calculations based on 2010 alone.
The lack of rain has drawn Israel into
a deeply critical water situation, necessitating an emergency plan which is set
to be presented to the cabinet in the coming weeks.
The year started out
with the hottest January in 60 years, broken only by the hardest thunderstorm
the Negev has seen since February 1975. While the storm hit the entire country,
it was particularly severe in the Negev.
The rest of the year was marked
by scarce rainfall, which culminated in basically no rainfall at all during the
entire month of November.
In the past 70 years, only 1946 and 1962 had a
similarly rainless November.
However, there were 10 days of rain in late
June – the most in June since 1994.
Temperature-wise, days in August
reached record highs.
In Har Canaan, a record 40.6 degrees for August was
reached. Beersheba topped that with 43.8 degrees.
And of course, the year
ended with Israel’s largest forest fire, as the hot and dry weather of November
continued into the beginning of December.

Winds of up to 120 kph wreaked havoc while the North and the
coast saw significant amounts of rain.
