Dewpoint values for Victoria

Hi all...

Following recent discussions about whether it's likely to be frosty in the mornings I contacted Ed Wiebe, who runs the UVic school-based weather network (and who is an avid cyclist).

If you go to their homepage (http://www.victoriaweather.ca) you will see that they have started reporting dewpoint values for their observation points. If you click on any school in their temperature contour plot you get a page that reports, among other things, the current dewpoint value for that site.

Cheers,
J.

Even more on dewpoint

Ed Wiebe has tweaked his site so that if you go here:
http://www.victoriaweather.ca/twod.php?zone=alls you can compare plots of temperature and dewpoint.

Ed cautioned that this is a work in progress and comes with lots of caveats. The biggest is that the school-based weather sensors are located on the roofs of schools (5-10m above ground). As dewpoint is a function of both temperature and humidity, and since ground temperatures can be colder than at 5-10m above ground, the risk of frost may be higher than these maps may suggest. So, user beware! That said, this is stll the best local dewpoint information available - thanks Ed!

Roland Rabien has also just updated his figbug weather site (http://figbug.com/weather), which I know that many of you use, and it now also reports dewpoint if you click on any observation point.

Cheers,
J.
