In most temperate places in the Northern Hemisphere, it will start to feel noticeably warmer from late March into April, with the real “consistently mild” feeling often kicking in by May.

The basic timeline

  • Late February to early March: You may get the first hints of milder days, but cold snaps are still common.
  • Late March: Daytime highs typically climb into low double digits Celsius (around 10–13°C) in places like the UK and similar latitudes, so it starts to feel more like early spring.
  • April: Average daytime highs around 13°C in the UK, more frequent sunny days, fewer hard frosts; this is when many people say it “starts to get warmer” in a sustained way.
  • May: Often the first month that feels properly warm, with average highs around 17°C in the UK and a decent chance of early-season warm or even hot spells.

A simple rule of thumb: once you reach late March and the clocks change to summer time in Europe (end of March) or spring is well underway where you live, the overall trend tilts toward warmer, even if a few chilly days still pop up.

Why it’s so cold now

Right now (late January 2026), several outlooks mention lingering cold linked to patterns like polar vortex disruptions and lingering winter circulation, especially for parts of North America and Europe. That means the next few weeks can still bring Arctic air outbreaks and frosty conditions even though days are slowly getting longer.

So if you’re staring out at grey skies and freezing temps wondering “when will it start to get warmer,” the realistic answer is: expect winter-style weather through February, more mixed but improving conditions in March, and a clear, consistent warming trend from April onward in many mid‑latitude regions.

In short: hang on through February; by late March you should start noticing the shift, and by May it will properly feel like the warmer part of the year in a lot of places.
