 | This uses data from the Automatic Weather Station at KEP, South Georgia. An hourly synoptic report (SYNOP) is automatically sent to the world Meteorological Data Centre and is used in forecasting models. The information on this page comes from the British Antarctic Survey site, which is updated every hour, but may be a few hours behind. |

For readers of Spanish, here is a key:
The 'A' is a high pressure system, the 'B' is a low, and you are on your own for the rest!
The meteogram is for the nearest model grid-point to the station, which means that it could be for 30km away from it and at a different height, as it is a 60km resolution model. This model doesn't have good resolution of the mountains, so it won't be very good for local effects. The main thing to note from the top chart is the solid outline, which shows the expected cloud thickness for the time. The next box shows the winds - the top lot show the wind direction. The continuous line gives the wind speed, but it may be for a few hundred feet up, so translates into more the maximum gust than the mean wind speed. The mean is likely to be 2/3 - 3/4 of the gust speed. The pressure and rain should be fairly straightforward, as is the temperature and dewpoint. Dewpoint is a measure of the moisture in the atmosphere and is useful for distinguishing different air masses. It can be helpful in determining if you have icing conditions - expect this if it is less than -5 or so. Don't pay too much attention to the wind chill, as it doesn't include any allowance for solar radiation.
