# dailyStatistics(for:startDay:endDay:including:) Returns daily weather statistics for the requested location, for each day from the start day to the end day, inclusively. ``` final func dailyStatistics(for location: CLLocation, startDay: Int, endDay: Int, including dataSets: repeat DailyWeatherStatisticsQuery) async throws -> (repeat DailyWeatherStatistics) where repeat each T : Decodable, repeat each T : Encodable, repeat each T : Equatable, repeat each T : Sendable ``` ## Parameters `location` The requested location. `startDay` The first day of the span, between 1 and 366. `endDay` The last day of the span, between 1 and 366. ## Return Value The requested daily weather statistics ## Discussion> Throws: Weather data error `WeatherError` The statistics returned for each day are derived from weather data recorded over the past decades, to the present date. Each item returned represents statistics for a particular day of the year, in UTC. This is a variadic API in which any combination of data sets can be requested and returned as a tuple. The following example will return statistics for the first 10 days of the year. ``` let (dailyPrecipitationStatistics, dailyTemperatureStatistics) = try await service.dailyStatistics(for: newYork, startDay: 1, endDay: 10, including: .precipitation, .temperature) ``` If `startDay` is greater than `endDay`, then a wrap around will occur. This next example will return statistics for days 365, 366, 1, and 2. ```swift let (dailyPrecipitationStatistics, dailyTemperatureStatistics) = try await service.dailyStatistics(for: newYork, startDay: 365, endDay: 2, including: .precipitation, .temperature) ``` > Precondition: `startDay in 1...366 && endDay in 1...366` --- Copyright © 2026 Apple Inc.
