Very wet weather is likely to persuade many regular cyclists and walkers to travel instead by car if they can. This is Bondi Junction after a storm hit Sydney.
The relationship between weather and our travel choices is complicated. We can't change the weather, but, with many other factors in play, good policy and design can reduce its impacts.

Why can't meteorologists call the weather correctly every time? Blame the battle of the weather models.
It’s more important to know whether there’ll be any weather than what the weather will be.

The skies can tell us when there might be trouble ahead.
The air doesn’t like to be under pressure just like us. The wind is the result of the air trying to escape from high pressure.
