There is a mobile page with current conditions, forecast, forecast map, station history (with drop down menu for today, yesterday, month, year etc. showing all parameters) and lastly a graph with drop down menu for time period and parameter.

There is also a history block where one can choose different parameters and a trends block with 1,3,6,12,24 hrs etc trends. Next is a forecast meteogram which is dynamic and moving the cursor over it will show all weather parameters at that point. Then easy to read forecast with dropdown the default using the Norwegian institute of meteorology values.(seems to be most accurate) Next is rainfall for today, this month, this year (from January) Drop down gives more options like seasonal(from September) etc. Rain balance is the stations values measured against 100 year rain data for Cannon Rocks district obtained from SA weather services.
