The chart tells a story. Between 3pm and 3.20pm, we got about 4mm of rain. Then from 3.22pm to 3.30pm, we got 7.6mm, and from 3.30pm to 3.53pm, another 8.6mm. That’s 16.2mm, or about 2/3 of an inch – a lot of rainfall in just 30 minutes. Even in wet New Zealand, that would be a huge downpour.
“Well, what of it?” you might say. “Surely you welcome rain in Adelaide?”
Indeed we do. But that half hour of heavy rainfall started at about 3.20pm, exactly when school gets out.
When the ducklings and I got home, with sodden shoes and school bags and raincoats, I made them hot chocolate.
