August weather forecast
Liberia, Costa Rica

The weather in August in Liberia, while similar in rain frequency to July, witnesses the highest monthly rainfall of the year, amassing 180mm (7.09"). The days become shorter with a drop in daylight hours, and cloud coverage continues to thicken, further limiting sunlight. But the decrease in sunshine doesn't significantly affect the monthly temperature averages. Relative humidity stagnates at 82% for the third consecutive month and the pressure experiences slight ups and downs. Amid the heavy showers, the winds slacken a bit more with the maximum speed dropping to 9.6km/h (6mph).

Temperature

The start of August in Liberia sees the average high-temperature at a still hot 30.8°C (87.4°F), showing little difference from July's 30.3°C (86.5°F). Liberia's temperature drops to an average low of 23.3°C (73.9°F) during the nights of August.

Heat index

The heat index in August is estimated at a blisteringly hot 41°C (105.8°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
Realize that the values for the heat index are set for shaded places and light winds. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Adhere to precautions and respect sun safety doctrines. Avoiding sunburn is vital.
