Rwanda Braces for Drier September as Temperatures Expected to Rise Slightly

Rwanda is expected to experience generally dry weather conditions throughout September, with rainfall forecast to remain below the long-term average in many parts of the country, according to the latest seasonal weather outlook.

The Rwanda Meteorology Agency expects rainfall totals during the month to range between 20 and 120 millimetres, compared with a long-term September range of 35 to 213 mm.

The drier conditions could add pressure to farmers, water resources and vegetation, particularly in areas already experiencing limited rainfall.

Daytime temperatures are expected to range between 22°C and 33°C, while nighttime temperatures are forecast to range from 10°C to 20°C. Both are expected to be slightly above the long-term mean for September, when maximum temperatures typically range from 21°C to 32°C and minimum temperatures from 10°C to 19°C.

For farmers, the combination of limited rainfall and warmer-than-usual temperatures could increase the need to carefully manage available soil moisture and water supplies.

The outlook also calls for moderate to strong winds of between 4 and 12 metres per second across the country.

Beyond agriculture, prolonged dry conditions can affect vegetation and increase the risk of environmental degradation where land is left exposed. Strong winds can also accelerate the drying of soils and vegetation, particularly in areas receiving little rainfall.

September is traditionally an important month for Rwanda’s agricultural calendar, making weather conditions particularly significant for communities whose livelihoods depend on rain-fed farming.

While the forecast points to generally dry conditions, rainfall will not necessarily be absent throughout the country. The projected range of 20 to 120 mm indicates that the amount of rain received may vary considerably from one area to another.

Meteorological authorities therefore encourage communities, particularly farmers, to follow localized weather updates and plan activities according to changing conditions.

For households and communities, the combination of warmer temperatures, limited rainfall and stronger winds also underscores the importance of using water efficiently and taking precautions against fires during prolonged dry spells.

As September unfolds, the challenge will be not only coping with less rain, but also managing the effects of a warmer and windier environment on farms, water sources and the wider landscape.
