A lot of plants are suffering from the heat and dryness. Luckily, most herbs are pretty tough. Most culinary, Mediterranean herbs are drought tolerant once established. Lavender, thyme, sage, rosemary and savory like hot weather and will tolerate drought. Established perennial herbs like oregano and tarragon should weather these conditions too.
If you're going to water, concentrate on annuals like basil and perennials like mint that like more moisture. Of course, it's difficult to duplicate a soaking rain when you water. Soaker hoses work well. If you're watering with a hose, make sure to water in early morning or late evening. During the heat of the day, you'll lose water to evaporation.
Some pretty plant combinations I've been admiring throughout the season -
Pink Coneflower and Russian Sage - classic combination, pretty pastel colors and contrasting textures.
Butterfly Bush & Day lilies - dark purple "Black Knight" butterfly bush and lemon yellow day lilies, opposites on the color wheel.
Blue Hyssop and White Coneflower - classic blue & white color scheme. Fine texture vs. coarse texture.
Gray Santolina & Rye - this is all about foliage - shiny, bright, fine textured santolina and the bluish-green foliage of rue
Pink perennial Poppies and Blue Flax - big, showy poppies with a blue-black center and the needle-like foliage and sky blue blooms of blue flax.
