The Department of Meteorology presents the assessment of the 2022 – 2023 hydrometeorological year

On September 30, 2023, the hydrometeorological year 2022-2023 was completed. According to the precipitation data available to the Department of Meteorology during the hydrometeorological year 2022-2023, the amount of precipitation recorded in the areas under Government control was 466.4mm. An amount of precipitation that ranks the specific hydrometeorological year in the 83rd place, in order of ranking from a total of 122 years with precipitation data for the island, as shown in Figure 1, below.

n relation to the reference period (1961-1990) the amount of precipitation recorded during this year’s hydrometeorological year (466.4mm) corresponds to 92% of the normal amount (503mm), as can be seen in Figure 2, which follows.

Of the 12 months of the hydrometeorological year 2022-2023 there were some months which exceeded their normal precipitation. These were: October 2022, during which the monthly precipitation reached 98.1mm or 300% of normal, September 2023 during which the monthly precipitation reached 12.1mm or 269% of normal, April 2023 during which the monthly precipitation reached 37.8mm or 126% of normal and November 2022 during which the monthly precipitation reached 53.4mm or 100% of normal. However, there were also some months during which the total precipitation was quite low. The month with the lowest total monthly precipitation amount was December 2022, with a total monthly precipitation of 34.5mm or 33% of normal.

At this point it is worth mentioning the temperatures that prevailed on the island during December 2022 and January 2023 since both of these winter months are presented as unusually warm months for several areas of Cyprus.
