Northampton is basking in the warmest conditions of the week today, 28 May 2026, but the hot spell will be short-lived. Temperatures are set to reach 31°C under sunny skies, with high UV levels prompting the Met Office to advise taking appropriate precautions outdoors.
This burst of summer-like weather is expected to peak today before a noticeable shift takes hold from Sunday. Temperatures will drop sharply to around 19-20°C, a fall of some 10 to 12 degrees, as cooler, more unsettled conditions move in. The change will feel pronounced after today’s heat.
Looking ahead to the start of next week, Northampton faces increasingly changeable weather. Cloud cover will build, and the chance of rain and light showers rises, marking a return to more typical spring patterns. Those planning outdoor activities over the coming days should keep an eye on the evolving forecast.
With the abrupt turnaround, any gardening or DIY projects best done in the dry are worth tackling while the sun remains. The high UV levels also mean even a short time outside without protection carries a risk of sunburn.
After today’s blast of warmth, a noticeably fresher feel will set in for the early part of next week. It is a stark reminder of just how quickly conditions can swing, even at the end of May.
