King Abdullah Economic City, Saudi Arabia: WaterSeer Ten Unit WaterGrid Yield Forecast

Climate: King Abdullah Economic City (KAEC) and Jeddah summers are long, humid, arid, and partly cloudy. Winters are short, warm, dry, windy, and mostly clear. Annual temperature varies from 18.3 C (65°F) to 39 C (102°F) and is rarely below 15 C (59°F). The hot season lasts from late May to late September with an average daily high above 36.7 C (98°F). The cool season lasts from early December to early March with an average daily high below 30.6 C (87°F).


Data is based on statistical analysis of weather data January 1980 to January 2016. Global climate change forecasts temperature and humidity will gradually increase and will persist for longer seasonal periods in this region.

Humidity: This coastal region experiences humid conditions year-round with over 8 months (early April to early December) of very humid conditions during from over 40% to over 90% of the month. 


WaterSeer Yield Curve: The WaterSeer yield curve is below. Yield is based on WaterSeer Sonoma model third party testing and trials under a wide variety of controlled and field conditions. Monthly yield is on the left vertical axis. The bottom horizontal axis is the average temperature. The Relative Humidity % (RH) is color coded in 10% increments.


King Abdullah Economic City Estimated Yield: KEAC and the Jeddah coastal region has an excellent coastal climate for WaterSeer WaterGrid deployment. A 10-unit WaterGrid will generate 200 to 250 liters per day on average and over 525 liters per day during optimal conditions. The yield forecast table below is predicted using annual weather data collected KAEC and Jeddah from 1980 to 2016. Quarterly yield is estimated for a small ten unit coastal WaterGrid for three types of installation; outside, such as a garden or greenspace, a hydroponics grow-house or vertical farm, and ‘Over Ocean’ deployment, such as off-shore facilities and small islands.
