In full sun, PyreneesPlot. It's about 26 in the shade.

Yikes! 37 in the shade must be unbearable. Similar to your toms, mine are really loving the warmer weather.

Phew!

Sun or shade? We had 37 in the shade on Sunday. Too hot, but the tomatoes put on about a foot of growth.

35C day and 15C nights. My plants are very confused
