Has it rained enough in Chicago?
The last rain heavy enough to soak in fell over a week ago. What has fallen since wet the leaves and no more.
Chicago has had 9.7mm of rain in the last 30 days. A normal August here brings 99.7mm — and the driest August in the last 30 years still managed 42.2mm. This is drier than anything on that record.
Rain in Chicago through a normal year
Across a normal year Chicago gets about 985.3mm of rain, most of it in May (113.2mm) and least in February (56mm).
That makes Chicago one of the wetter places this site covers in the United States in August — 9th of 30, against Tampa at the wet end (191.8mm) and Sacramento at the dry end (1.8mm).
What that means for what you grow
- Pots and hanging basketsWorst hit, and first to suffer. Very little soil, fully exposed, and nothing to fall back on — in this weather they can empty in a day.
- Salad and leafy vegShallow-rooted and quick to bolt once they run dry. First priority of anything in the ground.
- Beds and bordersA long soak that reaches the roots is worth more than a daily sprinkle, which only wets the surface and is gone by lunchtime.
- Established shrubs and treesFine as they are. They draw from far deeper than a dry spell reaches.
