I recommend Davis. The Vantage Pro2 preferably. But if your budget is tight, the Vue is also a great choice.
With the Pro2 the anemometer is detachable you have the ability to add solar UV leaf wetness soil moisture soil temperature.
The ticker tape is cool.
With the Vue smaller more compact sensor unit.
WeatherLink which is the software, used with Davis station can do alot with the data. But if your going to use a 3rd party program, I'd recommend Weather Display. That software goes the mile with features.
Also, Davis stations are high quality, tough, and durrable so in the harsh Saudi Arabian environment they should do well. As other stations might struggle.
