Global weather stations and data
This map shows all currently-reporting synoptic weather stations listed by the World Meteorological Organisation. Yellow circles indicate stations reporting surface observations and red squares show those reporting upper air observations.
Click on the station symbol when cursor changes to a pointing finger for station information and data. You can use the standard Google Maps map, satellite, zoom, drag and streetview features.
Details on how to read the information that appears when you click a station and get data for that station are given below.
When you click a station you can get the following information:
- Name and country of the station
- Its elevation above mean sea level in metres
- Pressure level is normally blank if the station reports barometer readings reduced to mean sea level (msl). Reduction to msl gives misleading readings for high elevation stations, so they report their barometer reduced to a standard isobaric surface which is shown here, e.g. 700 hPa.
- The Surface obs pattern is given for each of the 8 3-hourly observations a day, so YYYnYnYn means observations are made at 00, 03, 06, 12 and 18 UTC. + and * symbols are explained in the Obs remarks.
- Obs hours: If surface observations are made on an hourly or half-hourly basis, this is indicated by the symbol H or S, followed by the period of the day during which this is done.
- Upper obs pattern shows what upper air observations are made at each of the 4 6-hourly periods (00, 06, 12, 18 UTC) each day. The most common abbreviations are R for radiosonde (pressure, temperature, wind), P or W for wind and X for unspecified. So RWnRWW means radiosonde and wind at 00 and 12 UTC, wind only at 18 UTC and no observation at 06 UTC.
- Obs remarks are often self-explanatory. Full details are here.

To get Ogimet weather reports for a station:
- Click on the station to bring up the balloon
- Note the WMO No and click the link to Ogimet
- In the new window that comes up, put the number in the WMO No box. If the WMO No has fewer than 5 digits, pad it up to 5 digits by putting zeroes at left (e.g. 3162 becomes 03162).
- Pick the date(s) you want. Ogimet has quite a long archive. Default is latest.
- Click Send
- Available daily data for the period you nominated comes up (or an error message in spanish if no data available). The Daily Summary contains a lot of information, including a weather symbol for each 3 hours of the day - rest cursor on the symbol for an explanation.
- To get each observation during a day, click the date. The observations for 48 hours back from when you nominated come up.
- To get even more detail on each observation, click the date/time link.
