Best to wear a hat with a brim and a long sleeved shirt.

Should we go swimming with a hat? :)

I'm white enough that 5 mins of near midday sun gives me sunburns. In summer spf >30 is a must. Even day to day some sunscreen on my face and neck is a must.

Probably says a lot about where people live. The OP’s advice is a recipe for still getting skin cancer here (we get a max UV index at or over 11 every day for months where I live) - sunscreen is unavoidable to stay safe for a lot of the country because even little bits of incidental exposure add up. Whereas if you’re in the northern parts of US/Europe it’s probably OK.

I thought it was only sunburn that was dangerous rather than incidental exposure. This has been the advice for years now, has it changed?

Skin damage from UV is cumulative. How careful you have to be depends on your skin type but the general advice is that sun protection should be worn when the UV index is over 3, or if you're spending any extended time in the sun.
