35C is fine outdoors if they are well watered.

Totally agree with ES. High temperatures are not an issue, some shading is needed so that they don't get blasted by direct sun which can burn leaves. So they need to be protected from burning hot spots, but high ambient temperatures will likely just make them grow faster as long as they have adequate water (you can't overwater these, they'll take whatever you can give them) and fertilizer (they grow like tomatoes, so fast that you can almost watch them grow, and need to be fertilized for that high growth rate).

Shade is no problem but the temperature is all over the place at the moment.
Overnight temps this coming week range from 9C to 17C with daytime temps 19C to 29C and we are officially in Summer!
I will put them outside on the better days.
Hopefully next week the weather is a bit more settled.

I don't think that you have to worry about weather being settled... While a low of 9 deg C is on the chilly side, if it doesn't stay that low for more than a few hours (and warms up in the morning) I think that there would be no harm in just leaving it out... if it is near the house or a block wall that warms up during the day and radiates heat at night, it should be fine with the occasional cold jolt.

Good to know I can put them out on the table, that is close to the wall of the house.

Good call Diane. Better to be safe like that.
