Tzatziki contains two ingredients that naturally hold a lot of water: cucumber and yogurt. The diagnosis is therefore mostly a moisture-budget problem. Check whether the cucumber was salted and squeezed, whether the yogurt was Greek-style or strained, and whether extra liquid was added beyond the tested formula.
Symptom matcher
Which one looks most like yours?
Small visual differences can point to very different causes.
Check cucumber squeezing
Check yogurt thickness
Check salting and draining
Check liquid additions
Check residual cucumber moisture
Right now
Can it be saved?
Usually. Removing free liquid and increasing the proportion of thick yogurt can improve texture.
Limit: A sauce heavily diluted with cucumber water or excess lemon may need substantial rebalancing and will not match the original formula exactly.

Get to the first clue faster
Answer one question at a time. The result comes from the same reviewed diagnosis data below.
Was the grated cucumber squeezed firmly in a towel before mixing?
Was the yogurt thick Greek yogurt or strained yogurt?
Was the cucumber salted but its released liquid left in the mixture?
Did the sauce become loose only after extra lemon juice or liquid was added?
Dry the cucumber more
Undrained cucumber is the first moisture source to correct.
Likely cause: The grated cucumber was not squeezed dryUse thicker yogurt
Thin yogurt contributes excess whey from the start.
Likely cause: The yogurt was too thinDrain after salting
Salting only helps if the extracted water is discarded.
Likely cause: The cucumber was salted but the released water was left behindAudit liquid additions
Extra lemon or other liquid can loosen an otherwise correct sauce.
Likely cause: Too much lemon juice or other added liquid was usedCheck storage time
If the fresh sauce was thick, residual cucumber water may have migrated during storage.
Likely cause: The sauce sat long enough for more cucumber water to migrate outDiagnosis
Check the likely causes
Start at the top, but skip anything that clearly does not match your batch. Evidence labels describe the support for each cause, not a fake probability score.
The grated cucumber was not squeezed dry
The sauce loosens soon after cucumber is folded in, and liquid may collect around cucumber shreds.
Press a sample of the prepared cucumber in a clean towel; if significant water comes out, it was not drained enough.
Strain the tzatziki briefly and remove as much free liquid as practical.
Salt the grated cucumber, let it stand, then squeeze it firmly in a towel before mixing.
The yogurt was too thin
The yogurt itself pours easily before any cucumber or lemon is added.
Compare the starting yogurt with a thick Greek yogurt or strain it and observe how much whey drains.
Strain the finished sauce briefly in the refrigerator or fold in a small amount of thicker yogurt.
Use thick Greek yogurt or strain conventional yogurt before assembly.
The cucumber was salted but the released water was left behind
The cucumber bowl contains liquid after salting, and that liquid was mixed into the yogurt.
Review whether the salted cucumber was drained after its resting period.
Strain the sauce and re-season after the excess liquid is removed.
Treat salting and draining as one step: salt, rest, then discard the extracted water.
Too much lemon juice or other added liquid was used
The sauce was thick before seasoning but became loose after extra lemon juice or oil was added.
Compare the actual liquid additions with the tested recipe.
Add a small amount of thicker yogurt only if needed after correcting obvious free liquid.
Measure acidic and liquid ingredients before adjusting to taste.
The sauce sat long enough for more cucumber water to migrate out
The tzatziki was thick immediately after mixing but a watery ring appeared after hours in the refrigerator.
Stir the sauce and compare its texture immediately after mixing versus after the storage interval.
Stir, then drain a small amount of free liquid if necessary.
Squeeze the cucumber more thoroughly and avoid making the sauce farther ahead than the recipe requires.

Common misdiagnoses
Kitchen science
What is actually happening?
Food Network Kitchen explicitly says wringing moisture from cucumber keeps tzatziki thick and creamy. Other Food Network recipes salt and drain cucumber and strain yogurt for one to several hours before assembly. These methods consistently reduce free water before the sauce is mixed.

Tzatziki cucumber-draining comparison
Tzatziki made with salted, squeezed cucumber and thick yogurt will stay thicker than a batch using undrained cucumber or thin yogurt.
