June weather forecast
Santiago, Panama

The first month of the summer, June, is still a hot month in Santiago, Panama, with an average temperature varying between 23.1°C (73.6°F) and 30.2°C (86.4°F).

Temperature

The shift to June signals an average high-temperature of a still tropical 30.2°C (86.4°F), subtly varied from May's 31.3°C (88.3°F). Throughout June, the nighttime temperature in Santiago averages to a warm 23.1°C (73.6°F).

Heat index

For most parts of June, the heat index is calculated to be a blisteringly hot 40°C (104°F). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.
Heat index determinations are made taking into account the shade and light air movements. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'feels like', provides an understanding of perceived warmth by combining temperature and relative humidity. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

In June, the average relative humidity is 87%.

Take precautions and adopt sun safety practices. Protection against sunburn is obliged. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
