I’ve got 13 years of precip data for my house, first as part of the Albuquerque National Weather Service’s CityNet program, and now as a CoCoRaHS observer. But 13 years is too short a time period to calculate a meaningful average. Now, thanks to the new PRISM data, I have a clearer idea of what the long term looks like in my neighborhood:
That’s a PRISM estimate of average monthly precip during the 1981-2010 period now in use for US “climate normals”. You can see that October is usually one of our wetter months, averaging 1.18 inch (3 cm). This year I had 0 inches (0 cm).
Here’s the PRISM data compared to my shorter record:
For the first ten months of the year:
- 2012: 4.81 inches (12.2 cm)
- my period of record average: 8.43 inches (21.4 cm)
- prism average: 8.67 inches (22 cm)
