July weather forecast
Banjarmasin, Indonesia

Continuing the fine weather trend, July heightens the dry season experienced in Banjarmasin, Indonesia. Drier conditions imply fewer rains, consequently leading to a lower relative humidity level. Despite the high daytime temperatures, the nights experience slightly cooler temperatures. Enhanced clarity due to the low cloud cover increases visibility and maximizes sunlight hours. A mere 44mm (1.73") of rain marks July as the driest month of the year.

Temperature

January, June and July are known as Banjarmasin's coldest months, with an average high-temperature of 30.8°C (87.4°F).

Heat index

July's heat index is evaluated at an extremely hot 41°C (105.8°F). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
Data suggests that the heat index is set for environments in shade and with a light wind. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
