I though I was getting a late start on my tomato and pepper seeds.
Thanks to the rain and below average temperature, I'm repotting some of the larger plants.
I'm also anxious to be planting to get out into the heat and sunshine.
Robin when it is cool like this I deliberately delay planting my seeds for these crops. I have planted tomatoes and peppers as late as mid June and still harvested more fruit than I can use. You can stick them out early but those Cool temps will still prevent them from setting fruit. This is especially important at higher elevations.

Peppers and eggplant are fussiest right around blossom time. They'll have a poor fruit set if temperatures at night are below 55 oF or above 75 oF while they're blossoming, and they'll also drop their blossoms if daytime temperatures are above 90° F. These temperatures will also delay maturing of the fruit that does manage to set. Eggplant and peppers can also become stunted during cool weather and then not grow well once warm weather returns. Rapid growth is necessary for quality fruit production

The effect of temperature on flowering in tomatoes and peppers
It is well known that flowering, pollination, and fruit set of tomatoes and peppers can be adversely affected by temperature extremes. The effect of various temperatures during flowering and fruit set of peppers and tomatoes is shown in Tables 1 and 2.
Table 1: The effect of temperature during flowering and fruit set of tomato
Temperature
Effect on flowering, pollination, fruit set
Greater than 35° C (95° F)
Reduced fruit set
18.5 - 26.5° C (65-80° F)
Optimum for fruit set
Less than 13° C (55° F)
Misshapen or catfaced fruit may result
Less than 10° C (50° F)
Poor fruit set
Table 2: The effect of temperature during flowering and fruit set of pepper
Temperature
Effect on flowering, pollination, fruit set
Greater than 32° C (90° ) day temp.
Pollen sterility occurs, flowers may drop
16° C (61 ° F)
Optimum for flowering and fruit set
Less than 15.5° C (60° F) or greater than 24° C (75° F) night temp.
Poor fruit set
What you may not think about when you see blossoms and fruit developing, is that low temperatures experienced by the plant weeks before flower buds were visible, can also affect flowering and fruit set.
A tomato plant which experiences temperatures below 15.5° C (60° F) for extended periods of time will begin to flower profusely. These flowers may remain open on the plant for several weeks, without fruit being formed. Larger flowers and increased branching of clusters can show up as a result of low temperatures experienced by the plant weeks before flower buds are visible.
