The phenomenon surprised the park rangers who posted photos and videos on the social networks.

Eladio Solano, meteorologist at the Instituto Meteorológico Nacional (IMN) – national meteorological institute – said the strong wind gusts caused a windchill of 0 Celsius (32 Fahrenheit).

Solano added that there is no weather station at the Barva volcano, so it was not possible to say for certain that the temperature dropped to freezing.

But, weather stations at the Turrialba and Irazu volcanos recorded the low temperature of 5 Celsius during the night and early morning.
