The Guyana Hydrometeorological Service is advising the public to prepare for the strengthening of El Niño conditions as the country transitions out of the rainy season and into a period expected to bring hotter-than-normal conditions and an increase in hot spells from August all the way to October, 2026.
According to Hydromet’s latest Seasonal Outlook, the country is expected to experience a significant increase in the number of hot spell days from this month.
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.
During this period, the weather office is warning that there is likely to be reduced water availability for domestic use, agriculture and other economic activities, particularly in vulnerable communities in hinterland regions.
According to the Hydromet Office, reduced rainfall and higher temperatures is likely to place crops under moisture stress, affect pasture quality and increase water requirements for livestock.
“Higher temperatures may increase electricity demand as households and businesses rely more heavily on cooling systems, placing additional pressure on the national power grid. 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,” the Hydromet office explained.
The hydromet office also explained that the current dry spell also has several health implications. It noted that the 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.
As a result, the Hydromet office is advising the members of the public to stay hydrated throughout the day, conserving water where possible, especially during the prolonged dry periods and limiting strenuous outdoor activities during the midday hours of 11 a.m. to 2 p.m, in addition to wearing light, loose-fitting clothing
