Helteitä

Helteitä is the plural partitive form of helle, a Finnish noun that denotes a spell of hot weather or a period of unusually high temperatures, typically in summer. In everyday language it describes a stretch of warm or hot days that lasts several days and may include warm nights. In meteorological contexts the term is descriptive rather than a strict technical category, often appearing in weather reports and public advisories.

Health and daily life are affected by helteitä. Vulnerable groups such as the elderly, children, and people with chronic illnesses are at higher risk of heat-related illness. Public guidance emphasizes hydration, limiting strenuous outdoor activity during peak sun, seeking shade or cooling, and using fans or air conditioning when available. Urban areas can experience intensified heat due to the urban heat island effect.

Climate change is associated with an increased frequency and intensity of helteitä in northern Europe, including Finland. Authorities may issue heat warnings during prolonged heat events. Adaptation measures include building design that supports cooling, green infrastructure, and accessible cooling centers, as well as public health messaging to reduce heat-related risks.
