أرصاد | Arsad‎

You are a digital product reviewer with 10 years of experience. You have been asked to describe the official weather app from the Presidency of Meteorology and Environment (PMA), "Arsad."

Imagine you are planning a week-long outdoor excursion in Saudi Arabia—hiking through the Asir mountains, then diving in the Red Sea. You check a generic weather app and see "sunny, 35°C." That tells you almost nothing about the sudden afternoon flash floods in the wadis, the shifting sandstorm patterns near the Empty Quarter, or the precise visibility for your dive site. This is the precise gap Arsad was built to fill. This isn't a port of a global weather service; it is the official, authoritative weather and climate platform for the Kingdom of Saudi Arabia, pulling directly from the PMA’s national network of sensors, radars, and satellite data. It provides hyper-local, government-grade meteorological data that consumer apps simply cannot access.

Core Functionality and Data Layers

The primary value of Arsad lies in its data origin and specificity. It moves beyond the temperature/humidity/wind trifecta to offer a suite of specialized warnings and environmental monitoring tools. The home screen presents a clear, color-coded system for the National Center for Meteorology (NCM) alerts, using a four-tier warning system (Green, Yellow, Orange, Red) for specific regions. Tapping into a warning reveals the exact nature of the threat—be it heavy rain leading to flash floods, active dust storms reducing visibility, or extreme heat.

The app’s feature set is segmented for different user needs. For the general public, it offers standard 7-day and hourly forecasts with an interactive radar map, showing cloud cover, precipitation, and dust concentrations in real-time. For professionals and enthusiasts, it includes a dedicated marine forecast module, providing wave height, wind speed, and sea state for the Red Sea and Arabian Gulf. A critical tool is the "Visibility" forecast, essential for drivers and aviation. The app also provides a detailed air quality index (AQI) map, including data on PM10, PM2.5, and ozone levels, sourced from the national monitoring stations.

• Real-time, government-sourced weather alerts with color-coded severity and specific threat descriptions for every Saudi region.
• High-resolution interactive radar map displaying live precipitation, dust, and cloud movement across the Arabian Peninsula.
• Specialized marine forecast module with wave height, wind direction, and sea state for the Red Sea and Arabian Gulf shipping lanes.
• Hourly and 7-day air quality index (AQI) data, including PM10 and PM2.5 levels from the national monitoring network.
• Detailed visibility reports and dust storm tracking, crucial for desert travel and aviation safety.

User Experience and Practical Application

The interface is utilitarian and information-dense, prioritizing data clarity over aesthetic gloss. This is a tool, not a lifestyle app. The information is presented in both English and Arabic, with a toggle for language. The radar map is responsive, allowing pinch-to-zoom down to a city or district level. The alert system is the standout feature: it is reliable and precise. During a recent thunderstorm in Riyadh, the app issued a "Red" alert for the city center 45 minutes before the storm hit, complete with a polygon on the map showing the affected area and a text description of the expected intensity. This is the app’s core value proposition—providing actionable, life-safety information that is simply not available elsewhere.

The app does require an active internet connection to load the radar maps and alerts, but the forecast data itself caches reasonably well. The primary limitation is its geographic scope; it is exclusively focused on Saudi Arabia. For global weather, you will need another app. However, for anyone living in, traveling to, or operating a business in the Kingdom, Arsad is the definitive source for weather intelligence.

We suggest trying Arsad if you require precise, authoritative weather data for Saudi Arabia, particularly for safety-critical decisions involving travel, outdoor work, or marine activities. It is a free tool that provides a level of detail and official validation that no other weather app can match.
