July weather forecast
Chiang Rai, Thailand

July in Chiang Rai is known for its highest rainfall, measuring at 311mm (12.24"), making it the wettest month of the year. As the destination is in full swing of the rainy season, there are fewer daylight hours. The persistent rainfall brings about a mystical aura, transforming the city into a moist and green paradise. Humidity is at its peak, but the continuous rain keeps the overall temperature in check. For people who enjoy the monsoons, this is the month to witness Chiang Rai in its most authentic form.

Temperature

July's beginning signals an average high-temperature of a still hot 31.1°C (88°F), barely different from June's 32.1°C (89.8°F). During the nights in July, Chiang Rai observes an average low-temperature of 23.4°C (74.1°F).

Heat index

The average heat index in July is computed to be a blisteringly hot 42°C (107.6°F). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.
In reference to the heat index, it's for places in shade and with a slight wind. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Humidity

The average relative humidity in July is 82%.

Note: The maximum UV index of 12 during July leads to these instructions:
Implement every essential safety step. Individuals with fair skin might receive burns in less than 5 minutes. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun. Despite the cloud cover, sunscreen with an SPF of at least 30 should be generously applied and reapplied, particularly after a swim or an outdoor workout.
