As absurd as it may seem when it’s raining. It is actually a GOOD time to add a little supplemental water to the extremely parched forest around your home. While we received ~ ≤ 1" of rain last week, it is NOT a deep watering. Moist soil will imbibe water much more readily than dry soil and will conduct any added water deeper into the root zones of native trees, shrubs and wildflowers that ARE stressed by 2+ years of drought. On a cooler, more humid days, little moisture is wasted to evaporation. A half hour of watering in each area will deliver several inches of water that may last in the soil for a month or more. It will help struggling native plants while improving disease, insect and even fire resistance. In the early 1990's we had over 200 bark beetle-infested trees removed from around our old nursery location and not one within the areas that received some supplemental watering via the nursery irrigation. A few at the fringes had some beetle attack but the healthy trees "pitched-out' the insects.
