June marks the mid-point of the year in
Singapore. While there's a noticeable drop in relative humidity, the general climate parameters remain consistent with the preceding months. June's weather is marked by a slight dip in precipitation compared to
May. The city continues to enjoy long daylight hours and abundant sunshine, favourable for outdoor pursuits. The transition from May to June is smooth, with no drastic variation in weather conditions, ensuring a pleasant atmosphere for locals and visitors.
Temperature
The start of June in Singapore sees the average high-temperature at a still hot 31.3°C (88.3°F), showing little difference from May's 31.6°C (88.9°F). Singapore, during June, witnesses an average low-temperature of 24.8°C (76.6°F).
Heat index
The heat index for June is computed to be a scorching 43°C (109.4°F).
Alert: Heat cramps and heat exhaustion are likely to occur. Prolonged exertion can lead to heatstroke.
Note that heat index values are valued for light wind and location in the shade. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
Humidity
In June, the average relative humidity in Singapore is 83%.
Rainfall
In Singapore, in June, it is raining for 13 days, with typically 162mm (6.38") of accumulated precipitation. In Singapore, during the entire year, the rain falls for 178 days and collects up to 2343mm (92.24") of precipitation.
Sea temperature
May and June, with an average sea temperature of 30.2°C (86.4°F), are months with the warmest seawater.
Note: The surface water temperatures above 30°C (86°F) are arguably considered as unpleasant for swimming, and any intense water activity, as the refreshing effect of water is missing.
Daylight
With an average of 12h and 12min of daylight, June has the longest days of the year in Singapore.
On the first day of June, sunrise is at 06:56 and sunset at 19:08. On the last day of the month, sunrise is at 07:02 and sunset at 19:14 +08.
Sunshine
In Singapore, the average sunshine in June is 5.9h.
UV index
The months with the lowest UV index are June and
July, with an average maximum UV index of 11. A UV Index reading of 11, and higher, represents an extreme health hazard from exposure to the Sun's UV rays for the average person.
Note: In June, an average UV index of 11 transforms into the following instructions:
Enforce all necessary safety measures, unprotected skin may suffer burns swiftly. 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. Boost your sun resistance with garments that are densely woven yet spacious. Even if the day is cloudy, sunscreen with SPF of at least 30 should be applied generously and reapplied often, particularly after swimming or outdoor exercise. Take note! The UV strength of the Sun elevates when reflected off water and sand.
