The Hydrometeorological Service of the Ministry of Agriculture is forecasting wetter than usual rainfall conditions across all regions of Guyana for the months of November 2022 to January 2023 (Guyana’s secondary rainfall season). The usual secondary rainfall season will be augmented by persistent La Nina conditions during the season. Rainfall is expected to increase considerably from mid-November and continue at least to January, 2023.
During the upcoming rainy season, water levels in conservancies, reservoirs, and inland rivers across Regions 1 to 8 and 10 are likely to increase with a high risk of flooding. On the other hand, Region 9 would continue to be dry, but can expect more than the usual amount of rain days. The highest amount of rainfall is projected for Regions 1, 2, 3, 7 and Northern 8 with increasing concerns for Regions 4 and 5.
Regions 1 to 7 and 10 can expect a higher than usual number of wet days. Northern Regions can expect increases in the number of seven (7) day very wet spells. There is also a projection for a decrease in the number of seven (7) day dry spells during the forecast period, with most dry days and dry spells likely to occur in early November, 2022 and late January, 2023. The temperature outlook indicates that all regions can expect cool as usual to cooler night-time and day-time temperatures.
The possible implications for the upcoming season include more rain days than the usual amount which could be beneficial to some agriculture users. However, this is likely to cause disruptions to infrastructure projects and public transport, with there being the real possibility of land slippage in hinterland areas, especially in mining areas, where the soil may already be saturated.
The continued maintenance of drainage infrastructure is essential as the country progresses towards the wet season. Farmers are urged to take all the necessary precautions to secure crops and livestock in advance of significant rainfall events. Miners are also similarly cautioned to exercise maximum care on interior roads and on mining sites, while the applicable public health protocols should be activated across the Regions.
