A very curious thing. Today it rained in San Jose, California. For many years now, when something odd happens here, I look up the local long life station at the San Jose Airport on Wunderground, and that gives me the “typical” or normal averages (after way too many clicks) for comparison.
Rain in the first few days of October is an oddity here. Typically it waits until about Halloween. Sometimes a little before, often just the day after.
Today it rained.
So off to Wunderground. Get it focused on to the San Jose in California, not the dozen+ others around the planet. Look at history… No history. WT? Oh, I see, for some unknown reason it gave me the San Jose Japantown station. One with little history and located in an urban enclave a few streets from the airport. No worries, I’ll just change stations to the one that has been around the absolute longest and is used for all the climate stuff and aviation….
What? It’s not there? What?

I’d think maybe they moved it into the Santa Clara batch, but the map argues otherwise. Other Santa Clara stations are on the list and map. Nice big hole over the SJC airport. One wonders why…
As I’ve used the normals before, I have a copy saved somewhere. If I find it I’ll add it here; but my original intent of showing rain unusual this early in October has been replaced with real surprise that Wunderground is leaving out the most important station in the area.
One other side note: Notice the orange tags for stations with current temperature on them. Notice most of them are withing a couple of degrees F of each other but some are 5+ divergent. That is the nature of ground temperatures. They vary a lot with microclimate. There is no way any significance can be ascribed to changes in the 1/10 degree range when you have whole degrees from local foliage, pavement, wetness, buildings, etc
The basic notion of using such readings for a 1/10 C precision is ludicrous after even a casual examination of stations in an area and accepted for reporting use by folks like Wundergroud.
Update: Looks like the LAX Los Angles airport is also left out. El Segundo and Maple Avenue are as close as you can get… Is someone trying to hide the Airport Heat Island and how it biases “climate change” to the high side? Hmmm….
