Belém marks the beginning of the drier season. A steady decrease in rainfall is observed from the mid-year, compared to the previous months with immense downpour.

May's 88.3°F. Throughout June, Belém records an average temperature of 71.8°F at night.
Heat index
The average heat index in June is estimated at a blazing hot 114.8°F.
On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.
Understanding the heat index involves considering values for shaded locales with light wind. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Undertake all key precautions, as unprotected skin and eyes may get burns in no time. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat. Directly after outdoor activities or swimming, a broad-spectrum sunscreen with SPF 30+ should be applied generously and reapplied frequently. Be on guard! The reflective nature of sand and water boosts UV exposure.
