Weather in July

July, the same as June, in Ciderum, Indonesia, is another tropical winter month, with an average temperature varying between 19.9°C (67.8°F) and 30.4°C (86.7°F).

Temperature

The start of July sees the average high-temperature at a still hot 30.4°C (86.7°F), showing little difference from June's 30.3°C (86.5°F). Ciderum experiences an average nighttime temperature of 19.9°C (67.8°F) in the month of July.

Heat index

In July, the heat index is computed to be a very hot 39°C (102.2°F). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.
Consider that heat index readings are for situations in the shade and light wind. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', gives an indication of how one might feel in terms of heat after considering humidity. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Humidity

In July, the average relative humidity is 79%.

Rainfall

In Ciderum, during July, the rain falls for 21.3 days and regularly aggregates up to 87mm (3.43") of precipitation. Throughout the year, there are 305.8 rainfall days, and 2855mm (112.4") of precipitation is accumulated.

UV index

The months with the highest UV index are April, July through October, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high health hazard from exposure to the Sun's UV radiation for average individuals.
Note: In July, the maximum UV index of 7 translates into these guidelines:
Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
