Meteorological information about Qatar is best obtained from the UK. Sorry, but if you want the weather for the next few days, you'll have to go to BBC weather and their five-day forecasts. For tidal predictions, go to http://easytide.ukho.gov.uk/EasyTide/EasyTide/SelectPort.aspx
The local met website (thanks, bbb8) is an improvement on the earlier service, mind you. I once spent nearly an hour on the phone ringing the met office, harbour authority, coastguard etc and came away with the impression that no-one knew, or was even faintly inquisitive about, the next day's weather and tides. Even a same-day forecast is an advance on the previous service.
