When I lived in the more humid mid-west I used a drier set on the lowest setting.

You can also dry them in a super low heat oven. If you happpen to have an old one with a pilot light that stayed on all the time, it is the perfect heat. ou can do it in a regular oven by heating the oven to it's lowest temp; turn off the oven and let it cool down some; spread out the herbs in a single layer on top of paper towel on a sheet pan; put this in the turned-off oven and leave until the oven is totally cool. If necessary, you can remove the partially dried herbs from the oven, reheat, allow to cool down some and re-oven the herbs. You can do this until they're dry.

There is also a way to do it in the microwave, but I've never done it and don't know how it's done.

Personally, I think a drier is the easiest...... unless you live in a very dry climate, like CA, where you just lay them out on a counter and they dry with no help at all. :^)

I have been drying herbs for a long time, even before I started gardening I would dry herbs I bought from the supermarket because they are so much better than the dried herbs in jars.

Basil, oregano, sage, anything with a green main stem I found are best dried by hanging upside down. The trick is to separate the leaves as much as possible because when they are bunched together they don't dry as quickly or thoroughly. I take a needle and some nylon thread and pull it through the stems. You can then move them left/right and get the spacing you want. Then, put them into your pantry or a closet. Darkness seems to help them dry faster though I don't know why. I usually take some push pins and string the herb chain along a shelf, or even on the back of the door. Takes about 2 weeks, maybe a little longer, and your herbs are dried nicely and good for 4-6 months. Now, if you are drying a field of herbs at once, then you will want to look at a quicker drying method, but the old slow hand method gets the best results. Even with your humidity, this should still work.

Air circulation is probably the most critical factor in a humid climate. Make sure your bundles aren't too large, so air can flow through easily and set a fan (or two) nearby so the air blows on the herbs. Also, try drying herbs in a car. You would be surprised how like a low set oven your car gets on even a warm day! Spread out a clean sheet/towel/whatever in the back seat or trunk (if you don't have tinted windows, use the trunk), spread out your herbs in a single layer, park somewhere hot! Remember to turn your herbs over after a day or two. Within 3-4 days, you will have crispy dry herbs.

Thanks Arturo! Love the idea of stringing them across on a string! Just got done string up alot of Basil will see how this works. In the past I always used the bundle and hang method and the center of the bundle was always black. This method looks like they will dry faster. I have mine in my Hot Water Heater Closet right now.

I used to have no problem drying my herbs in bunches if I kept the bunches small (nickel sized) and had them inside with a/c. Last summer I switched to a method that someone on this forum recommended. Now I use stacked sweater racks. It works great and is faster than any other type of non-heat drying that I've done. One important thing to increase drying speed is to remove the leaves from the stems. The stems store lots of moisture in them. And the thinner the layer the faster they'll dry. Also stir them up every day or so.

For leaves that will fall through my sweater rack, like rosemary and oregano. I'll often remove the leaves from the stems and then dry on a cookie sheet (less than 1/4 inch deep). Stirring every day or so. Rosemary takes a while to dry, but it hasn't molded for me (again in the a/c).

I use a dehydrator.
The dehydrator cost me $15 from Wmart and I also use it to make beef jerky and sun dried tomatoes.

I did basil in the microwave. Worked great. :-)
