The Hydrometeorological Service is advising the public to prepare for hotter-than-normal conditions and more frequent hot spells as El Niño strengthens and Guyana transitions out of the rainy season.
In a statement, the Hydromet department said the conditions were expected from August until at least October 2026.
El Niño refers to the unusual warming of ocean-surface temperatures in the central and eastern equatorial Pacific, accompanied by weaker trade winds.
According to the department’s latest Seasonal Outlook, Guyana could experience as many as 80 hot-spell days this year, compared with the historical annual maximum of 30. A hot spell is defined as two or more consecutive days of extreme temperatures.
Regions Four, Five, Six, Eight and Ten are expected to experience the highest frequency of hot spells. The entire country is likely to record fewer wet days and above-normal daytime and nighttime temperatures.
The Hydromet department warned that reduced rainfall and higher temperatures could place crops under moisture stress, affect pasture quality and increase livestock’s water requirements.
The prolonged dry period could also reduce water available for domestic, agricultural and other economic uses, particularly in vulnerable hinterland communities.
Higher electricity demand from increased use of cooling systems could place additional pressure on the national grid, while extreme temperatures could cause heat stress and discomfort in classrooms.
Low river levels may disrupt the movement of people, goods and essential services in some hinterland areas. Unpaved roads could also become dusty, reducing visibility.
Dry vegetation and prolonged high temperatures are expected to increase the risk of bush and forest fires, particularly in forested and savannah regions.
The Hydromet department also warned of an increased risk of dehydration, heat exhaustion and heat stroke, especially among children, elderly persons, those with underlying medical conditions and outdoor workers.
The public was advised to remain hydrated, conserve water and avoid strenuous outdoor activity between 11 am and 2 pm. Persons should also wear light, loose-fitting clothing.
Schools were urged to maintain adequate drinking-water supplies, promote heat-safety measures and monitor official weather advisories.
The Hydromet department also advised against burning rubbish or vegetation and urged farmers to monitor crops and livestock and ensure continued access to good-quality water.
The agency noted that significant rainfall could still occur during the period, although El Niño generally produces warmer and drier conditions. It said it would continue monitoring the situation and issuing updates.
