Weather in June
Temperature
June's onset witnesses a minor shift in the average high-temperature, moving from a moderately hot 81.1°F (27.3°C) in May to a tropical 87.6°F (30.9°C). In Swansea, the average nighttime temperature during June is a pleasant 70.3°F (21.3°C).Heat index
The heat index value during June is estimated at a sweltering 100.4°F (38°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', shows a temperature sensation when both heat and moisture conditions are combined. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
