At beach destinations, the tropical sun is intense year-round. UV levels are particularly high between 10 a.m. and 4 p.m. The reflection from water and white sand intensifies exposure, so you can burn even while swimming or sitting under an umbrella.
In highland destinations like Mexico City or San Miguel de Allende, the thinner atmosphere at altitude allows more UV rays to reach your skin. Many visitors underestimate sun exposure in cooler mountain climates and are surprised by sunburn.
We recommend using SPF 30 or higher sunscreen, reapplying every two hours, and wearing hats and protective clothing during peak sun hours. Consider reef-safe sunscreens, as many marine destinations now require them to protect coral ecosystems.
