Hydromet forecasts ‘above normal’ rainfall in months ahead

The Hydrometeorological Service hosted its 19th National Climate Outlook Forum on Monday at the Herdmanston Lodge in Georgetown, unveiling the country’s weather forecast for the upcoming months.

With mild La Niña conditions expected through March 2026, officials are urging stakeholders to prepare for wetter-than-usual weather conditions across most regions. However, temperatures may be warmer-than-usual during the daytime with cooler-than-normal nighttime temperatures.

From December 2025 to February 2026, Guyana is expected to experience near-normal to above-normal rainfall across the country, except for the far southern portions of Regions 6 and 9, where below-normal rainfall is expected.

At the forum where the information was shared, Deputy Chief Hydromet Officer, Haymattie Danny said the climate outlook engagement is vital for preparing the country at the onset of each rainy season.

“Climate services are powerful tools, they bridge the gap between traditional and scientific knowledge. By harnessing this information, we can navigate a changing climate with greater confidence and create a more sustainable future,” Danny said.

She further stated that engaging both public and private stakeholders is essential to fully understand climate impacts, better prepare for extreme events, and make more informed decisions.

Specialist Meteorologist Komalchand Dhiram noted that although La Niña is expected to remain mild, experts will closely monitor its evolution over the coming weeks and months.

For agriculture, the outlook projects that rainfall could boost crop growth and productivity, but warmer conditions may also increase heat stress, along with the threat of pests and diseases. Intermittent dry-hot spells could further challenge rice yields despite the general expectation of above-normal rainfall.

Water levels in reservoirs and conservancies are likely to reach or approach full capacity. However, increased evaporation may reduce the amount of water actually available. Heavy rainfall combined with rising temperatures could also heighten the risk of surface water contamination and algal blooms.

In public health, prolonged wet weather is predicted to create ideal conditions for mosquito breeding, increasing the risk of malaria and other vector-borne diseases. Higher temperatures may also raise the likelihood of heat-related illnesses in both humans and livestock. Flooding and contaminated water could lead to outbreaks of waterborne diseases.

The forum also highlighted disaster risk concerns. Flash floods remain likely, posing threats to crops, property, and infrastructure. Flood-prone areas may face transportation disruptions, while persistent rainfall and site flooding could delay construction projects.
