säsongligt

Säsongligt is a Swedish adverb meaning "seasonally" or "in a seasonal manner." It describes phenomena, practices or patterns that recur with the seasons on a yearly cycle.

Etymology: It is formed from säsong, meaning season, with the suffix -ligt, and is used to qualify actions or states. In everyday speech the more common forms are säsongsmässigt or årstidsmässigt, while säsongligt appears mainly in formal, academic or descriptive writing.

Usage: The term is relevant across several fields when describing seasonal variation. In agriculture and forestry, production or yields may be säsongligt tied to planting and harvest times. In tourism and retail, visitation and demand often follow a säsongligt pattern, peaking in summer or around holidays. In energy, weather-dependent consumption may be säsongligt higher in winter.

Statistics and data analysis: säsongligt is sometimes used to refer to the timing of patterns, while the standard term for the magnitude of repeating patterns is säsongsmässig variation. Säsongsjustering (seasonal adjustment) is a related concept for processing time series data.

Limitations: The word is relatively formal and can sound technical in everyday speech; more common alternatives include säsongsmässig, årstidsmässig, or simply seasonal in borrowed usage.

Examples: Efterfrågan på vinterkläder är säsongligt hög under höst- och vintermånaderna. Turismen är ofta säsongligt högre under sommaren.
