に marks the time when something happens.

So 午後に晴れたら means if/when it clears up in the afternoon.

A lot of time expressions do not use に, such as 今日, 明日, and 毎日, but words like 午後, 3時, or 週末 often can take に when you want to mark the time more clearly.

This is because たら is a grammar pattern, not just a simple past tense.

It is made from:

• 晴れた = past plain form of 晴れる
• ら = part of the conditional pattern

Together, 晴れたら means if it becomes sunny / when it clears up.

So the た here does not mean the whole sentence is talking about the past. In a たら conditional, Japanese uses the past-form base even for future situations.

Usually in weather talk, 晴れる means to become clear / to clear up / to turn sunny.

So 午後に晴れたら most naturally suggests:

• if it clears up in the afternoon
• if it turns sunny this afternoon

It sounds a little more like a change in weather than simply describing a general sunny condition.

In Japanese, subordinate clauses usually stay in plain form, even when the main sentence is polite.

So this is normal:

• 午後に晴れたら = plain form in the if/when clause
• 出します = polite form in the main clause

Japanese does this all the time:

• 時間があったら、行きます。
• 雨が降ったら、帰ります。

The politeness is usually shown in the main verb at the end.

晴れれば is possible, but it sounds a bit more formal or more like a straightforward condition.

• 晴れたら = very natural for a planned action after a condition is met
• 晴れれば = also possible, but slightly less conversational here

晴れると is not a good fit here, because と is generally not used when the main clause is the speaker’s deliberate future action, decision, or intention.

Since 出します is something the speaker plans to do, たら works much better.

ぬれた靴 means wet shoes or more literally shoes that got wet.

Yes, ぬれた is the past plain form of ぬれる (to get wet), but here it is being used before a noun to describe that noun.

Japanese often uses verb forms this way:

• 買った本 = the book I bought
• 壊れた時計 = the broken clock
• ぬれた靴 = the wet shoes / the shoes that got wet

So this is not a separate past-tense sentence. It is a noun-modifying phrase.

Yes, you could, but the nuance is a little different.

• ぬれた靴 = wet shoes / shoes that got wet
• ぬれている靴 = shoes that are in the state of being wet

In many everyday situations, ぬれた靴 is the more natural and concise way to say wet shoes.

ぬれている靴 is not wrong, but it can sound a bit more explicit or descriptive.

Japanese often leaves out information that is understood from context.

So even though English would usually say I will put my wet shoes outside, Japanese can simply say:

• ぬれた靴を外に出します。

The listener will usually understand that the speaker means I, and that the shoes are probably the speaker’s shoes unless context says otherwise.

If you wanted, you could add 私は, but it is often unnecessary.

Because Japanese nouns usually do not change form for singular vs. plural.

So 靴 can mean:

• a shoe
• shoes
• a pair of shoes

The exact number is understood from context.

In this sentence, English will usually translate it as shoes, because that sounds natural.

Literally, it means will put/take [them] outside.

The verb is 出す, which is a transitive verb meaning things like:

• take out
• put out
• bring out

So:

• 靴を外に出します = I’ll put the shoes outside

This is different from 出る, which is intransitive:

• 外に出る = to go outside
• 靴を外に出す = to put the shoes outside

That を shows that 靴 is the thing being moved.

Yes, へ is possible, but に is more natural here.

• 外に出します = put them outside, to that location
• 外へ出します = move them toward/outside

With 出す, に often sounds better when you are focusing on the destination or final placement of the object.

So 外に出します is the most natural choice for put them outside.
