It is possible that this page will report a problem where no problem exists.

The site location should be at the mark shown -- or very close. Clicking within the map area (or you can drag the 'AN138' marker) will display the latitude/longitude of that point.
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.
Can you help with location quality? Please indicate if the marker on the map points at the weather instrument cluster:

There are no photographs of the station. If you have pictures of this location, then please upload them to Flickr (detailed instructions) and add the two tags 'wxtagged' and 'wx:id=AN138'. If the picture is of the weather station itself, then please also add the 'wx:station' tag as well. Please geotag your images, and those coordinates may be used in the estimation of the location of this site.

Recent observations from this weather station can be downloaded as a CSV file suitable for importing into various spreadsheet programs: last 7 days, last 14 days, last 28 days, last 56 days. This data can also be linked directly from Excel using a Web Query. The main link goes to the page with the data on it, and the IQY link is the Web Query that will access it: last 7 days (IQY: last 7 days), last 14 days (IQY: last 14 days), last 28 days (IQY: last 28 days), last 56 days (IQY: last 56 days).
All the means and standard deviations shown below are from the last 28 days. Change analysis period to Last 3 days Last 7 days Last 14 days Last 8 weeks Last 13 weeks Last 26 weeks Last 39 weeks Last 52 weeks
|The wind vector is the average wind over the relevant period. Note that if the wind blows North for half the time at 2 knots, and then blows South for the other half of the time at 2 knots, then the result is zero -- i.e. North wind and South wind will cancel out. Over time, the direction of the wind and of the analysis should match pretty well. If the lengths of the vector are different, then it could mean either that your anemometer reads high or low, or that you are in a more shielded or more open space.|

You can look at those for comparison purposes. The average difference between your station and each station below is listed as well. This may allow you to detect local stations which are erroneous. You can also use these numbers to adjust your instruments -- especially if a number of ASOS stations have similar differences to your station. Also, try increasing the analysis period to more than the default 28 days. The difference is only given if both stations report reasonably often during each day. Some stations only report every 6 hours, and this makes the average of less interest. In this case, the average is not displayed. The values reported are the differences between this station and the neighboring station. I.e. if the difference is positive, then this station is reading higher than the neighboring station. Since this station has not been reporting continuously during the analysis period (it missed 2 days out of 28), the offsets below may not be accurate.
