Ground frost is an extremely rare weather event in tropical countries like Costa Rica.

In mountainous areas where humidity was above 60% and temperatures dropped to roughly 32°F (0°C), frost accumulated on the surface, leading to the occurrence of frozen ground.

This chilly weather impact was observed at dawn on Tuesday in high mountainous regions of the country, including the Turrialba Volcano in Cartago Province and Chirripó Summit in the Talamanca Mountain Range.

Several local witnesses to this weather event posted photos and videos on social media showing the odd freezing of grasslands near the Turrialba Volcano and the Chirripó Summit.

The Climate Institute states that low temperatures were recorded in the country's mountain regions between Monday night and dawn on Tuesday. The lowest temperatures measured were 36.86°F (2.7°C) at Chirripó Summit and 42.44°F (5.8°C) at Turrialba Volcano.
