Experts in Costa Rica have warned residents and visitors to take precautions against an impending heatwave expected to hit the country over the next couple of months. According to a recent statement from the National Meteorological Institute (IMN), Costa Rica will experience elevated temperatures and intense ultraviolet (UV) radiation between March and April.
What to Expect
IMN climatology expert Daniel Poleo explained that the positioning of the sun during March and April will cause solar rays to beam down more directly over Costa Rica. This phenomenon, known as the “Zenithal Sun,” leads to greater solar intensity and exacerbates the sensation of heat.
While the Easter holiday period is typically associated with high temperatures, Poleo emphasized that “it will be even more intense this year.” He said that from March 15 to April 15 specifically, Costa Rica will undergo an influx of perpendicular UV rays and heightened radiation levels.
Peak Hours and At-Risk Areas
UV rays tend to peak in intensity between 10 AM and 2 PM. Poleo noted that while UV intensity does not directly correlate with rising temperatures, radiation will still reach extreme levels. As such, he recommends avoiding sun exposure during peak hours. During this time, the shifting tilt of the earth’s axis means that shadows will be nearly imperceptible.
Contrary to popular belief, coastal zones do not experience the worst radiation. Places like the Central Valley and mountainous regions exhibit higher UV indexes due to their altitude. Meanwhile, the lowered elevation of beaches causes radiation strength to diminish.
Areas like the Irazú and Poás volcanoes warrant extra protection against UV rays. Besides radiation concerns, temperatures may spike above 40°C (104°F) over the coming months.
Precautionary Measures
In light of these forecasts, Costa Rican officials advise all residents and visitors to take proper precautions against heat and UV exposure over the next two months. Recommendations include:
- Using high-SPF sunscreen frequently
- Limiting direct sunlight between 10 AM and 2 PM
- Wearing protective clothing to cover bare skin
- Monitoring local weather alerts
Proactivity is key to remaining safe during this anticipated extreme heatwave. Without proper safeguards, people risk severe sunburns, heat illnesses, and heightened skin cancer risk.
Compounding Effect – US Travel Advisory
The heatwave warning comes after the U.S. State Department advised American citizens to practice heightened caution when traveling to Costa Rica due to crime rates. Though violent offenses like armed robbery, homicide, and sexual assault remain relatively uncommon, minor crime still poses the greatest danger to tourists. To counter this, Costa Rican officials have bolstered security resources around popular tourist destinations.
Despite warnings of intense heat, UV radiation, and petty crime, Costa Rica remains one of Central America’s most breathtaking countries to explore. By taking proper safety measures and avoiding peak sun hours, visitors can still fully experience all the natural wonders and Pura Vida lifestyle that makes Costa Rica such a treasured global destination. As with any trip abroad, exercising vigilance provides peace of mind amid a truly life-enriching experience.
