March weather forecast
Organabo, French Guiana

As March unfolds, rainfall becomes a less frequent visitor to Organabo. Though the weather remains humid, it's less intense than February, with the cloud coverage easing up slightly. The temperature continues its gradual climb from February, but overall, remains supportive of the city's typical tropical climate. Nevertheless, the strongest gusts of wind this month reach a peak of 14.3km/h (8.9mph), providing occasional brisk respite. As the sun starts to shine for an increased duration, glimpses of the dry season on the horizon become evident.

Temperature

Organabo marks the onset of March with an average high-temperature of a still warm 29.5°C (85.1°F), subtly divergent from February's 29.1°C (84.4°F). In March, the average low-temperature is a pleasant 22.8°C (73°F).

Heat index

For March, the heat index is evaluated at a very hot 37°C (98.6°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.
Be advised, the heat index considers values for conditions in shade and with a light breeze. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Adopt measures and apply sun safety strategies. Shielding from skin and eye damage is necessary. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. Boost your sun resistance with garments that are densely woven yet spacious.
