Extreme all-direction wave conditions and joint probabilities of high waves and high water levels are derived at selected locations in the southern Arabian Gulf. The wave conditions are obtained using the spectral wave model SWAN with wind and offshore wave information procured from ocean weather, supplemented with local water level records. Wave transformations from offshore to nearshore and waves generated by local wind conditions are derived using wind speed and direction, offshore wave height, peak period and direction and water level inputs to the SWAN model. The model predicted extreme 3-hourly wind speeds for return periods ranging from 0.06 -200 years and the wave conditions for each storm. The study indicates that future sea level rise to 2058 gives 1:50, 1:100 and 1:250 return period water levels of 2.64, 2.71 and 2.79 mCD respectively at Jebel Ali.

As part of the Arabian Sea Monsoon Experiment (ARMEX), several automatic weather stations (AWSs) were installed on the west coast of India, and some among them have been recording weather data for more than one year. Here temporal variations observed at three coastal stations, namely Honnavar, Karwar and Vijaydurg during July 2002 to December 2003 are presented. The seasonal variations in air temperature, humidity, wind speed, etc., are along the expected lines. A strong diurnal variation in rainfall pattern is observed, but the dependence on local time is different at Honnavar and Vijaydurg which are not more than 250 kilometres apart. It is shown that the surface pressure exhibits strong variations on different time scales throughout the year, and the dominant time scales shift with the seasons.
