Visakhapatnam embraces summer. With a discernible escalation in temperature, the sun blazes hotter and longer, with days extending to an average of 12.5 hours. The peak temperature scales up markedly from 26.1°C (79°F) to 35.3°C (95.5°F), rendering this month notably warmer.

Temperature
The introduction of April notes a subtle temperature variation to a torrid 35.3°C (95.5°F) from
March's 33.8°C (92.8°F). Visakhapatnam's nighttime temperature in April falls to an average of 26.1°C (79°F).
Heat index
For most parts of April, the heat index is appraised at a burning hot 52°C (125.6°F).
Heed: Expect heat cramps and heat exhaustion. Continued action may cause heatstroke.
Observations indicate that the heat index values are for shady locations with light wind. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Practice every essential safety step. People with fair skin could receive burns in fewer than 5 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense. Even on cloudy days, a sunscreen with a minimum 30 sun protection factor should be generously applied and frequently re-applied, including after every swim or outdoor exercise. Be wary! Reflections from sand and water make UV radiation more intense.
