Real-Time Weather PRO v1.3.6 (23 Feb 2026) is a Unity plugin that functions as a standalone extension of the Unity editor, enabling the collection of real-time weather data for use in game components. It supports integration with a variety of sky and weather systems, including Easy Sky (HDRP), Enviro Sky and Weather (Standard, URP & HDRP), Enviro 3 - Sky and Weather (Standard, URP & HDRP), Tenkoku Dynamic Sky (Standard), Massive Clouds Atmos (Standard, URP & HDRP), Expanse Volumetric Skies (HDRP), Crest Ocean (URP, HDRP), and KWS Water System (URP, HDRP). All integrations can be imported from the Unity Asset Store.
The plugin offers a Forecast Timelapse Simulation feature, allowing users to customize the simulation speed of weather scenarios using data from weather providers or user-defined inputs to recreate time-lapse effects with day and night cycles. Weather data is sourced from public weather websites, with support for prioritizing weather providers by region, adjusting update frequencies, and using nearby location data when a specific location cannot be queried.
Input methods include country, state (for the USA), city names, and latitude/longitude coordinates. The plugin integrates with multiple weather and maritime data APIs, including Open Weather Map, Tomorrow.io, Stormglass.io, and MetOcean. Users can request hourly or daily forecast data from Tomorrow.io (up to 108 hours or 14 days) or OpenWeatherMap (up to 48 hours or 7 days) and simulate weather with customizable transition and simulation speeds, including loop options.
Custom weather profiles can be created, edited, and saved for future use, with configurable simulation durations and parameters. Historical weather data from OpenWeatherMap can be saved for later use. The plugin is simple to set up and includes built-in scene simulation capabilities for supported sky and water systems, as well as the ability to send weather and water data to a custom simulator.
Compatible with desktop, macOS, Linux, and console platforms, the plugin requires an active internet connection to fetch and update weather data. Available at: https://assetstore.unity.com/packages/tools/utilities/real-time-weather-pro-232520
