In most temperate places in the Northern Hemisphere, it starts to feel noticeably warmer from late March into April, but “truly warm” weather often waits until May or even June, depending on where you live.

The super short answer

  • You’ll usually feel the first mild days in late winter or early spring (late February–March).
  • More consistent pleasant days (light jacket, maybe no coat) tend to show up in April–May.
  • Real “summer-like” warmth often doesn’t lock in until June or later in cooler regions.

If you tell me your city or region, I can give a much more precise timeline.

Why “when does it get warmer?” is tricky

Weather doesn’t flip from cold to warm on a fixed date; it kind of stumbles its way there.

  • In some coastal or northern areas (like New England or the Netherlands), you can have cold snaps and even snow in April, but also random warm days in February or March.
  • In warmer southern regions, springlike 70s can show up already in late March or early April, with 80s following not long after.
  • Climate change is nudging winters milder in many places, which can make early spring feel “weird” (warm days mixed with unseasonal cold or rain).

Think of it less as a switch and more as a tug‑of‑war between lingering winter and incoming summer.

Rough timeline by region (Northern Hemisphere)

These are broad patterns, not guarantees:

  • Southern areas (e.g., US South, Mediterranean climates)
    • First springlike 70 °F (low 20s °C): often late March–early April.
* Many days feel warm by April; summer heat by May in some spots.
  • Mid‑latitude inland/continental (e.g., US Midwest, Central Europe)
    • Noticeable warm-up: March–April.
* More reliable mild weather: late April–May.

* Hot summer conditions: usually June onward.
  • Cooler coastal / northern regions (e.g., New England, North Sea coasts)
    • Random warm days can appear as early as March, but they’re hit‑or‑miss.
* “Feels like spring” more consistently from mid‑April into May.

* Truly warm, summery stretches may hold off until June or even July some years.

An example: people in Rhode Island report that you may see scattered warm days in March, but the more steady 50–60 °F daytime and 40–50 °F nights often start around mid‑April, with July finally bringing reliably warm nights.

What “warmer” might mean for you

You might be asking:

  • “When can I put away heavy winter gear?”
    • In many cool regions, you’re usually safe to stash the heaviest stuff sometime in April, but keep a few light sweaters or jackets because chilly evenings can hang on into May.
  • “When will it feel like proper spring?”
    • Often:
      • Mild but unstable in March.
      • More stable, pleasant days in April–May.
  • “When is it actually hot?”
    • In many temperate climates, June–August is when heat really settles in, with occasional spikes to 30 °C / 86 °F or more.

Mini forum‑style perspective

You’ll see a lot of comments like:

“There will be some warm days in March, but the consistent springtime weather starts in mid‑April.”

and

“The weather gets a bit warmer the second half of February and is generally good in April and May.”

These capture how locals experience the shift: a tease of warmth early on, then a more settled pleasant period a month or two later.

Quick SEO‑style notes

  • Focus phrase: “when does it get warmer” works well paired with your location (e.g., “when does it get warmer in Boston”).
  • People often search this alongside terms like “spring weather,” “first warm day,” or “when can I wear shorts again.”

TL;DR: In many temperate northern places, expect the first hints of warmth in March, more reliable mild days in April–May, and true summer warmth from June onward—exact timing depends heavily on your local climate.

If you share your city or country, I can narrow this down to typical months and temperatures for where you are.
