July weather forecast
Singapore, Singapore

July in Singapore ushers in a continuation of the warm and humid conditions from June. Interestingly, the average daylight remains constant at 12.2 hours, offering ample time to enjoy the breadth of Singapore's attractions. Relative humidity and temperature show little variation, contributing to a fairly static climate throughout. Subtle changes in weather patterns provide a seamless transition from June to July. As a result, Singapore continues to offer an attractive climate for outdoor adventures and exploration.

Temperature

The onset of July in Singapore manifests an average high-temperature of a still hot 30.9°C (87.6°F), demonstrating a minor variation from the preceding month. Throughout July, Singapore records an average temperature of 24.6°C (76.3°F) at night.

Heat index

For most parts of July, the heat index is computed to be a blistering 42°C (107.6°F). Undertake additional safety actions, risk of heat cramps and heat exhaustion is significant. Persistent activity may induce heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Humidity

The months with the lowest humidity are February and July, with an average relative humidity of 82.8%.

Rainfall

The month with the least rainfall is July, when the rain falls for 13 days and typically collects 159mm (6.26") of precipitation.

Note: Ideal surface water temperatures for any water activity fall between 25°C (77°F) and 29°C (84.2°F), offering maximum enjoyment for lengthened periods.

Daylight

In July, the average length of the day is 12h and 11min.
On the first day of July, sunrise is at 07:02 and sunset at 19:14. On the last day of the month, sunrise is at 07:05 and sunset at 19:16 +08.

Sunshine

In Singapore, the average sunshine in July is 6.1h.

UV index

The months with the lowest UV index in Singapore are June and July, with an average maximum UV index of 11. A UV Index reading of 11, and higher, represents an excessive health risk from exposure to the Sun's UV rays for ordinary individuals.
Note: The daily maximum UV index of 11 in July interprets into the following advice:
Practice all essential precautions. Protection against sun damage is crucial. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades. Directly after swimming or an outdoor workout, generously apply and reapply a broad-spectrum SPF 30+ sunscreen. Stay alert! Reflective properties of sand and water amplify the Sun's UV radiation.
