The mid-summer months in Jacmel, including July, continue to display warm temperatures and frequent rainfall. Leap to 56mm (2.2") in precipitation denotes the presence of significant rain despite being lower than in May. The weather remains quite warm, with sea temperatures remaining on the higher side. Prominently, the month signifies a vital part of the wet season requiring tourists to plan their activities accordingly.

Temperature

The advent of July reveals an average high-temperature of a still warm 29.5°C (85.1°F), showing minimal difference from the prior month. The temperature during July nights demonstrates a small drop from the daytime highs, settling to an average of 24.9°C (76.8°F).

Heat index

July's heat index is computed to be a very hot 35°C (95°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Note: The UV index of 7 during July leads to these advisories:
Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized. Heads up! UV intensity is amplified by reflections from water and sand.
