Green leaf lettuce and spinach didn't make it beyond May here. Planted in
late Feb. Spinach lasted for about 2 months, small. Leaf lettuce stopped
producing any good leaves around the same time and went into strictly
flowering.

You should already have spinich and lettuce planted. They will produce
throughout the winter. Seed multiple times so you have plants of different
ages -- you are correct that sometine in May it gets too hot. These are cold
weather crops!
