The Guyana Hydrometeorological Service (Hydromet) is advising the public to prepare for the strengthening of El Niño conditions as the country transitions out of the rainy season into a period expected to bring hotter-than-normal conditions and an increase in hot spells from August to at least October, 2026.
El Niño refers to the unusual warming of ocean surface temperatures in the central and eastern equatorial Pacific, paired with weaker trade winds. According to Hydromet’s latest Seasonal Outlook, the country is expected to experience a significant increase in the number of hot spell days. While Guyana historically records up to 30 hot spell days annually, the current forecast indicates that as many as 80 hot spell days could occur this year.
The highest frequency of hot spell days is likely to be experienced in Regions 4, 5, 6, 8 and 10. A hot spell is two or more days of extreme temperatures. All of Guyana is expected to experience a decrease in the number of wet days and above normal day and night-time temperatures.
Potential Impacts
The anticipated warmer and drier conditions may have implications for several sectors. However appropriate preparedness measures can reduce possible impacts. These include:
Agriculture: Reduced rainfall and higher temperatures is likely to place crops under moisture stress, affect pasture quality and increase water requirements for livestock.
Water Resources: the extended dry period is likely to reduce water availability for domestic use, agriculture and other economic activities, particularly in vulnerable communities in hinterland regions.
Energy: Higher temperatures may increase electricity demand as households and businesses rely more heavily on cooling systems, placing additional pressure on the national power grid.
Education: Prolonged periods of extreme temperatures are likely to increase the risk of heat stress and classroom discomfort.
Hinterland Transportation: Low water levels may affect river transportation in some areas, potentially disrupting the movement of people, goods and essential services. Additionally, unpaved roads are likely to become dusty, reducing visibility.
Forestry and Wildfire Risk: Dry vegetation and prolonged high temperatures are likely to increase the likelihood of bush and forest fires, particularly in forested and savannah regions.
Public Health: Prolonged exposure to extreme heat may increase cases of dehydration, heat exhaustion and heat stroke, particularly among children, older adults, people with underlying medical conditions and those who work outdoors.
Public Advisory
The Hydrometeorological Service is therefore advising members of the public to take all the necessary precautions by:
- Staying hydrated throughout the day
- Conserving water where possible, especially during the prolonged dry periods
- Limiting strenuous outdoor activities during midday hours (11 a.m. – 2 p.m.)
- Wearing light, loose-fitting clothing
- Ensure there is adequate drinking water in schools, promote heat safety and monitor official weather advisories
- Avoid activities that could ignite fires, including the burning of rubbish or vegetation
- Paying close attention to crops and livestock, ensuring continued access to good quality water
The Hydrometeorological Service emphasizes that while El Niño typically results in warmer and drier conditions, days with significant rainfall is still possible during this period. The Service will continue to monitor these conditions and provide timely updates to support preparedness and informed decision-making.
