April weather forecast
Gia Thuận, Vietnam

April, like March, in Gia Thuận, Vietnam, is another fiery hot spring month, with an average temperature fluctuating between 35°C (95°F) and 26.7°C (80.1°F).

Temperature

As March turns into April, the average high-temperatures rest at a still fiery hot 35°C (95°F), showing a minor variation from the prior month. Gia Thuận observes an average nighttime low-temperature of 26.7°C (80.1°F) during the month of April.

Heat index

During April, the heat index is estimated at a life-threatening hot 48°C (118.4°F). Stay alert: Heat cramps and heat exhaustion are expected. Heatstroke is a likely outcome of ongoing activity.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly important for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

UV index

With an average maximum UV index of 8, April is the month with the highest UV index. A UV Index reading of 8 to 10 represents a very high health vulnerability from exposure to the Sun's UV radiation for the ordinary person.
Note: In April, a daily maximum UV index of 8 leads to the following instructions:
Ensure you're always protected. Unprotected skin can get damaged in moments. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
