Agrometeorological Dekadal Bulletin-2nd DEKAD JUNE 2026
Summary:
The second dekad of June 2026 was characterized by widespread and intense rainfall across the country. Nationwide, accumulated rainfall ranged from 110.0 mm to 390.0 mm, with the coastal (southern) regions recording the highest rainfall totals. Parts of Lofa, Bong, and Grand Gedeh Counties received the lowest rainfall amounts during this period, while the remaining counties experienced moderate to high rainfall.
Summary:
PET: During the Second Dekad of June 2026, Lofa, Nimba and north of Bong experienced intense sunshine with high evapotranspiration rates. However, the south (coastal) region experienced lowest evapotranspiration rate while the central region experienced moderate evapotranspiration rate.
Summary:
SMI: During the second dekad of June 2026, soil moisture conditions were above normal across the country. The persistent rainfall led to increased soil moisture levels, resulting in saturated soils over most parts of the country.
Summary:
Maximum Temperature: The Second dekad of June 2026 was marked by variation in maximum temperature across the country. Parts of Sinoe, Rivergee, Grand Kru and Maryland counties experienced relatively low maximum temperature. However, central Nimba, east of Bong, north of Rivercess and Grand Bassa experienced highest maximum temperature. During this period, maximum temperature ranged between 27.4°C and 29.0°C.
Summary:
Minimum Temperature: The Second Dekad of June 2026 was characterized by variation in minimum temperature. Some parts of the coastal counties (south of Montserrado, Margibi, Bassa, Rivercess, Sinoe, Grand Kru and Maryland) experienced high minimum temperature, while Lofa, north, central of Nimba and extreme north of Bong county experienced the lowest. Minimum temperature during this period ranged from 22.3°C to 26.3°C.

Relative Humidity: During June 2026, high relative humidity is expected to across the northern parts of the country. However, low relatively humidity is anticipated in Montserrado, Margibi, Grand Kru, and the western part of Grand Bassa County. Average relative humidity during the month is forecast to range between 88.2% and 90.2%.
Maximum temperature: Expected between 27.5°C and 29.7°C. Higher maximum temperatures are expected in Grand Cape Mount, Bomi, western Montserrado, and southern Gbapolu Counties, while Margibi, Grand Bassa, Sinoe, Grand Kru, Lofa, and Maryland Counties are anticipated to experience lower maximum temperatures. The remaining areas, including Bong, Nimba, northern Grand Gedeh, and parts of Gbapolu Counties, are expected to record moderate maximum temperatures.
Minimum temperature: Minimum temperature across the country in June 2026 is anticipated to range between 21.2°C and 25.0°C. The highest minimum temperature is anticipated to occur along the coastal region including counties such as Maryland, Grand Kru, Sinoe, Rivercess, Grand Bassa, Margibi and Montserrado while the lowest minimum temperature is expected in Lofa and parts of Nimba, Bong, Gbapolu and Grand Gedeh counties.
Farmers advisory
Increased rainfall across the country has resulted in increasingly saturated soils in many areas. Rainfall is also expected to intensify during the last dekad of June 2026. Therefore, farmers, agricultural stakeholders, and agro-industries are advised to take the following precautions in their agricultural activities:
Farmers located along major river systems are strongly advised to take additional precautionary measures in their farming activities. This is due to the expected continuation of heavy rainfall, which may lead to rising river levels and possible flooding of nearby farmlands and access roads. Such conditions could disrupt farm operations, damage crops, and make transportation of agricultural products difficult. Therefore, farmers are encouraged to closely monitor local weather updates, secure farm inputs and harvested produce, and avoid crossing flooded roads or waterways during this period.
Farmers are also strongly encouraged to regularly monitor their crops, as persistent heavy rainfall may create favorable conditions for increased pest infestations across farmlands. In the event of any pest outbreaks, farmers should promptly take appropriate pest control measures, including the use of recommended agricultural practices and approved pesticides where necessary, to minimize crop damage and yield losses.
Livestock producers are encouraged to keep their animals in protected shelters, as increased rainfall may contribute to the spread of animal diseases. Prolonged wet conditions may also lead to respiratory illnesses, including colds, in livestock. Therefore, producers are advised to closely observe their animals for any signs of illness or abnormal behavior that may indicate disease. If any symptoms are detected, prompt and appropriate veterinary measures should be taken to safeguard animal health.
Vegetable producers are advised to shift their farming activities to upland areas, as lowland fields are likely to become saturated due to persistent rainfall, which may result in crop damage and reduced yields. In addition, producers are strongly encouraged to properly design and lay out their fields, including the use of appropriate drainage and soil conservation practices, to minimize the risk of soil erosion and nutrient loss during heavy rainfall events
