It’s been dry, but did you know it’s been THIS dry?
The 3 month total rainfall, 0.25″ at PDX from July to September, is the driest 3 month period in all of Portland’s history!
It was the combination of no rain in August, almost no rain this month, and a drier than normal July. In all other years, we had one or two dry months, but never three. The next closest was June-August 1951. That year we had 0.35″.
No sign of rain yet, although some models are hinting at a cold trough later next week that could finally bring us showers.
We are not in drought conditions since typically this is the driest time of year anyway, plus we had tons of Spring rainfall. Remember June? 4″ rain here in Portland. That said, our smaller shrubs and trees are probably very stressed since they need at least SOME rain later in the summer. So keep watering!
