Hai Phong, Vietnam

The searing heat continues into June with little respite from the high humidity levels. Despite the intense sun and heat, coastal activities thrive thanks to the sea temperature reaching its yearly high. Hai Phong in June presents a unique blend of heat, humidity, and high rainfall. This month receives a whopping 298mm (11.73") of rainfall. Despite these challenging conditions, Hai Phong retains its charm, offering visitors opportunities for memorable experiences.

Hai Phong experiences an average high-temperature of a still hot 32°C (89.6°F) in June, subtly different from May's 30.5°C (86.9°F). Hai Phong witnesses an average low-temperature of 25.7°C (78.3°F) throughout the month of June.

Heat index

Throughout June, the heat index is computed to be a life-threatening hot 47°C (116.6°F). Mindful: Heat cramps and heat exhaustion are to be expected. Extended physical effort might result in heatstroke.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', unifies temperature and humidity readings to offer a comprehensive feel of warmth. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values hold particular significance for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. 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. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Note: The maximum UV index, 12 during June, leads to the following recommendations:
Enforce every key safety measure. Those with light skin might get burns in a matter of minutes. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes. Prompt application of a broad-spectrum sunscreen, SPF 30+, is necessary after a swim or an outdoor workout and it should be re-applied every two hours. Take warning! Reflective sand and water surfaces intensify the Sun's UV rays.
