I rarely bake bread so can't answer from personal experience but co-pilot returned this to your query.

Reducing Water in Bread Recipes During Humid Weather

In high humidity, you can safely reduce a bread recipe’s water by about 10% (roughly 1–4 tablespoons or 1/8–1/4 cup depending on batch size) and add it back gradually until the dough reaches the right consistency academiedupain.com+1.

How much to reduce

• Small batches (single loaf): Cut back by about 2 tablespoons Food Lovers Recipes.
• Multi‑loaf batches: Cut back by about 1/4 cup Food Lovers Recipes.
• General rule: Reduce total water by ~10% of the recipe amount academiedupain.com.
  Add the reduced water back in small increments while mixing until the dough feels smooth, elastic, and not sticky.

Why humidity changes water needs

In humid air, flour absorbs moisture from the environment, making dough wetter than expected eatopeia.com. This can cause:

• Faster yeast activity and over‑proofing The Bread Guide+1
• Sticky, hard‑to‑handle dough eatopeia.com
• Weaker gluten structure and denser bread eatopeia.com

Reducing water helps counteract this extra moisture and keeps dough handling and baking more predictable.

Practical tips for humid baking

1. Measure and adjust gradually – Start with the reduced amount, mix, then add a little more if the dough is too dry Food Lovers Recipes.
2. Use cold liquids – Ice‑cold water or chilled ingredients slow yeast growth and help control proofing The Bread Guide+1.
3. Consider reducing sugar – Less sugar slows yeast activity in humid conditions academiedupain.com+1.
4. Add a bit of salt – Salt can help control fermentation and strengthen gluten academiedupain.com+1.
5. Proof in a cooler spot – Use a fridge, air‑conditioned room, or cooled bowl to slow yeast The Bread Guide.
6. Switch to bread flour – Higher protein content can improve structure in humid weather academiedupain.com+1.

Example adjustment

If your recipe calls for 1 cup (240 ml) water for a loaf:

• In high humidity, start with ~220 ml (about 2 tbsp less).
• Mix, check dough texture, and add up to 1–2 tbsp more if needed.

By making these small, controlled changes, you’ll avoid sticky dough, over‑proofing, and dense bread, while keeping your loaves well‑structured and flavorful The Bread Guide+3.

That AI has never baked bread.

It depends on the bread recipe, the flour you're using, the air in your actual kitchen/workspace, etc. My mother taught me at her knee how to adjust the challah (her recipe is very picky) with more water or more flour to be just right. There is a baseline amount of each, but the flour is a rather wide range, and include what goes in during kneading and shaping.

Most single rise (plus shaped) bread doesn't require that much adjustment--if you're talking same flour in the same kitchen and oven. Often, a good recipe will come out right BUT if your dough feels too dry or too wet, add a pinch of flour or a drip of water. You can't ruin it. Just make sure what you add is well mixed in before adding more..

So add a little more flour rather than fiddling with decreasing the water?

yeah Pillog, it seems you said virtually the same thing.as the AI sources.

My answer would be no - and it's always pretty humid here.

I think when you've made lots of bread doughs, after awhile, you just know what the consistency should be, and either add more dry or wet ingredients, depending.

So add a little more flour rather than fiddling with decreasing the water?

Either or. Go with your gut. My objection to the AI is that all the possibilities were rolled up together and quantified in a way that won't actually work, and is confusing as well. The reality is what Carol said. Porkchop's question is its own answer.

PC, in your first mixing of the ingredients, you can hold back a little water (a spoon or two) if you're worried, and add it in later as you need it (and knead it). And if it seems too wet, add a pinch of flour. We're talking small quantities. According to a food scientist who did a cookie lecture a friend took me to, one teaspoon of water is the difference between crisp and chewy cookies in a batch of three dozen.

You didn't say what kind of bread or how big a batch. I'm talking for approx. 1 lb. finished., if you think your flour has absorbed a lot of water from the air--which is the difference between unusual humidity and constant--it's more important than ever to let it stand mixed up without the yeast for an hour, first. That way the flour absorbs the water. If you bloom the yeast separately, or are using starter, be sure to include that water in your calculations. Add the dry or bloomed yeast, or starter, after the hour and stir it in well, then you can start assessing if the water content is right. If it seems just a little dry, start kneading with wet hands and see if the kneading process brings the moisture to the fore. If you're using a machine to knead, wet your hands and shake them over the bowl. As kneading progresses, you'll recognize whether it seems too wet or dry, and you can adjust with a pinch or a drip.

I hope this helps. Good luck.

We're pretty humid here in Michigan in the summer, but I never adjust the amount of liquid in my bread recipes because of it. I check the texture and consistency of my bread dough each time I make it, no matter what time of year, and adjust accordingly. Sometimes it needs more liquid, sometimes a bit more flour, sometimes it is fine.

I often hear people say they weigh everything for their bread but that doesn't work for me because mine is slightly different each time. There are so many factors involved including the ones mentioned above, i.e. humidity, the age of your flour, the brand of your flour, the size of your eggs because eggs are not a manufactured product that is always the same.

I have baked enough bread that I know how it should look and how it should feel, depending on the loaf. Grandma's Farmhouse White is smooth and dryer than the slightly sticky and much wetter artisan type boule with a crunchy crust and it's all very slightly different each time.

Bread is both an art and a science. Experience brings out the art, I tend to add flour rather than with hold water, but I know after years of baking how the dough needs to feel.

My husband bakes sandwich bread weekly, weighing ingredients. We live in an extremely humid environment, butnour home is air conditioned so the humidity level is pretty low and constant.

Weighing may help with the accuracy of a new to you recipe, but any measuring form will work for home baking so long as you're consistent. For bakery sized batches weighing works a lot better because the size magnifies innaccuracies. Those pioneer grannies did fine measuring a "cup" as the chipped teacup with the broken off handle. Experience is more valuable than tools. I use weight or volume depending on the recipe. With no recipe, I tend to weigh for bread, where I'm using a combination of flours and change them. For a cake, measurement accuracy is much more important (as is the humdity of the flour!), but I always (almost) use the same flour, and use volume because that's how I learned and what I know. I've tried converting to weight but it comes out wonky.

Just remember after asking a question to an AI system, ask this followup: What was incorrect about that answer? if you haven't done that before now, you might be surprised...

This is all helpful. What I'm gathering is to adjust according to feel and look.

Yup.
