Weather in May
Temperature
With the onset of May, Newcastle observes a minor temperature ascent, with the average high-temperature adjusting from April's warm 76.6°F (24.8°C) to a still moderately hot 83.5°F (28.6°C). Newcastle's average low-temperature during May nights is observed to be a comfortable 62.8°F (17.1°C).Heat index
The heat index in May is estimated at a tropical 87.8°F (31°C). With constant exposure and activity, a state of weariness might ensue, leading to potential heat cramps.Be aware that heat index ratings are designed for shaded locations and minor breezes. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. 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 largely significant for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.

Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
