Latitude: 50° 26' 0" N (deg min sec), 50.4333° (decimal), 5026.00N (LORAN)

The elevation does not correspond with the estimated elevation (78 metres (256 feet) -- source SRTM 3 arc-second: All Northern Latitudes) at that point. Either the location or the elevation (or both) are almost certain to be incorrect. Please use the 'send the updated information' link below to update the location or elevation.

If the displayed location (or elevation) of the weather observing location is incorrect, please drag the marker to the right location (or click in the right location), and then send the updated information. Please note that we are trying to spot either the Stevenson Screen (or equivalent) or the location where the barometric readings are taken.

The best way to get elevation is to consult a topographic map. Make sure that you know whether the contours are marked in feet or metres. Note that handheld GPS receivers do not provide readings of elevation accurate to better than 10-20 metres (technical discussion). If you do not have access to a topographic map, then a GPS receiver is acceptable, but make sure that it is operating in 3D mode and let it average the position for at least five minutes.

For more information on reading maps, please see the Topo Map Reading Guide -- in particular it discusses how to read contours.

The location information for this site was gathered from 5 data sources. The source which most closely matches the consensus is chosen. Many of these sources only report the location to the nearest minute (or hundredth of degree). This can lead to the marker being placed noticeably incorrectly.
