June weather forecast
Liberia, Costa Rica

Liberia weather in June sustains a typical combination of a wet season. Temperatures continue to slide, initiating a cooling trend for the rest of the year. Winds ease off, while daylight hours appear to be at their zenith. The increase in cloud cover limits the extent of sunshine received each day. Expected rainfall rises slightly to 160mm (6.3"), up from 149mm (5.87") in May, the city experiences the most rainy days observed in a year.

Temperature

The arrival of June in Liberia records an average high-temperature of a still tropical 30.8°C (87.4°F), closely related to the 32.9°C (91.2°F) observed in May. During June, Liberia consistently records a temperature low averaging a moderately hot 23.8°C (74.8°F).

Heat index

The heat index value for June is estimated at a blisteringly hot 41°C (105.8°F). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.
Heat index's context suggests values are appropriate for shady areas and slight breezes. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Humidity

In June, the average relative humidity is 82%.

UV index

The months with the highest UV index are January through October and December, with an average maximum UV index of 7. A UV Index of 6 to 7 symbolizes a high threat to health from unsafe exposure to UV radiation for the ordinary person.
Note: The UV index of 7 during June translates into the following guidance:
Stand by precautions and apply sun safety measures. Evading sunburn is of great importance. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. For optimum UV protection, wear sun-resistant attire complemented with a hat and quality shades.
