November weather forecast
Oranjestad, Aruba

Entering November, Oranjestad, Aruba, begins experiencing a steady decrease in temperature from the highs of October, setting the stage for winter. Rainfall remains high, peaking at roughly 94mm (3.7") typically spread over 10.6 days. The arrival of these rains often couples with increased cloud cover, reducing the hours of sunshine. Correspondingly, the duration of daylight shrinks further, raising a curtain on the approach of the winter season. Despite the drop in sea temperature, it remains warm enough for visitors to enjoy water activities.

Heat index

November's mean heat index is estimated at a blisteringly hot 42°C (107.6°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.
Consider that heat index readings are for situations in the shade and light wind. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. Combat UV radiation's detrimental effects with sun-safe clothing and UV-blocking eyewear. Applying and reapplying a broad-spectrum sunscreen with a minimum SPF 30 after every two hours, outdoor workout, or swim is recommended. Stay aware! UV radiation is magnified when reflecting off sand and water.
