October weather forecast
Gressier, Haiti

October fosters a clear transition in Gressier's weather, gradually phasing out high temperatures characteristic of the previous months. This gradual cooling, along with a contraction in daylight hours, distinguishes October from September and November. Rainfall levels decrease from those prevalent in September, yet the humidity remains relatively high. Coinciding with this, the sea temperature begins to fall, indicating a slow march towards the winter season. The consistent wind speed complements the lowering temperatures, providing outdoor enthusiasts an opportune moment to enjoy the remaining warmth.

Heat index

October's mean heat index is evaluated at a sweltering 35°C (95°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are essentially critical for children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage. Be mindful! Sand and water reflections can up the Sun's UV exposure.
