The Ministry of Health is warning Guyanese to brace for unusually hot conditions, possible flash flooding and increased risks of several climate-sensitive illnesses as the country moves through the final three months of 2026.
The warning was issued in collaboration with the Hydrometeorological Service as Guyana transitions from very dry conditions to a mixture of dry and wet periods between October and December.
According to the agencies, the country is likely to experience more dry days and hot spells than usual, with a high chance of above-normal daytime and nighttime temperatures.
Of particular concern is the risk of heatwaves, with the Heat Index expected to reach dangerous levels between 11:00hrs and 14:00hrs.
Temperatures above 32 degrees Celsius, coupled with high humidity, could increase the risk of heat exhaustion and heat stroke. Outdoor workers, elderly persons, children and pregnant women are among those considered particularly vulnerable.
Residents are being urged to drink plenty of water, seek shade or cool areas, wear light clothing and avoid strenuous activities during peak heat hours. Persons experiencing dizziness, weakness, headaches or confusion are advised to seek medical attention immediately.
Meanwhile, although below-normal rainfall is anticipated across Guyana, the authorities have warned of an increased possibility of flash flooding from late November.
Floodwaters could increase exposure to waterborne illnesses, including gastroenteritis and leptospirosis, through contaminated water and mud. Residents are therefore being encouraged to use treated or boiled water, wash their hands regularly and avoid contact with floodwater where possible.
The combination of rainfall and high temperatures could also create favourable conditions for mosquito breeding, particularly in coastal and urban areas, increasing the risk of vector-borne diseases.
Persons are being advised to eliminate standing water around their homes, use mosquito repellent and bed nets and wear long-sleeved clothing.
The authorities are also monitoring Saharan dust, although concentrations are expected to remain very low during the October-to-December period. Elevated dust levels can trigger asthma attacks and respiratory irritation, particularly among children, elderly persons and people with existing lung conditions.
The Ministry is urging persons with respiratory conditions to limit outdoor activity during dusty periods, keep windows closed and use a KN95 mask where necessary.
Residents experiencing serious symptoms or medical emergencies are being advised to seek assistance from the nearest health facility.
