Dzeltenais karstuma brīdinājums
18.07.2026. dienas vidū Rīgā gaidāms stiprs karstums - gaisa temperatūra paaugstināsies līdz +27...+28º. ESI INFORMĒTS, ka ir gaidāms stiprs karstums!

Dienas vidū UV indekss sasniegs vidēji augstu līdz augstu līmeni, tādēļ nav ieteicams ilgstoši atrasties tiešos saules staros.
