A lot depends on where you live, the SW gets more rainfall than the East. Also the sort of plants you have and the type of soil, whether it's well drained or holds onto water.
I live in SW France where it can get very hot and dry, so I water flower beds every week or two and the vegetable garden, which is well drained, shallow soil on rock, every 2 - 3 days. I water the plants in pots every other day in summer I always give a good soak, little and often means the water doesn't get down to the roots. I have soaker hoses in the long thin flower beds and I use a sprinkler for the others.
Sometimes there is a water ban, but just here I'm lucky. I ring the local water board and there is usually plenty because of the rocks, caves and underground rivers.
