Weather Analysis<\/h4>\n\n\n\n

May 2026 was a cool and changeable late-spring month, with a mean temperature of 10.7 \u00b0C<\/strong> \u2014 very close to, and marginally above, the station’s long-term May average of 10.4 \u00b0C (2004\u20132025). The month’s highest temperature, 23.1 \u00b0C<\/strong>, was recorded on 23 May<\/strong>, the warmest moment of an extended mild spell that dominated the final third of the month. The lowest reading, 0.5 \u00b0C<\/strong>, occurred in the early hours of 7 May<\/strong>, when clear skies and light winds during a cold-air outbreak brought temperatures to the brink of frost \u2014 though, notably, the month passed without a single sub-zero reading.<\/p>\n\n\n\n

The month divided clearly into two halves. The opening two weeks were dominated by cool, often raw conditions: between 3 and 14 May, daily mean temperatures hovered mostly between 6 and 9 \u00b0C, with several days failing to exceed 10 \u00b0C even at their peak. From mid-month onwards the pattern relaxed, and the period from 19 May to month’s end brought consistently double-digit daily means, culminating in the 23 \u00b0C warmth of the 23rd and a second push to 21.8 \u00b0C on the 30th. Only two days of the month reached the 20 \u00b0C threshold.<\/p>\n\n\n\n

Relative humidity averaged 73 %<\/strong>, spanning a wide range from a very dry 23 % during sunny, well-mixed afternoons to 97 % in damp and rainy conditions \u2014 a spread typical of May, when strong daytime insolation can dry the boundary layer dramatically.<\/p>\n\n\n\n

Air pressure averaged 1012.1 hPa<\/strong>, with considerable synoptic activity. The barometer peaked at 1028.2 hPa on 9 May<\/strong> under a cold but settled high-pressure ridge, and bottomed out at 991.8 hPa on 13 May<\/strong> as a low-pressure system delivered the month’s heaviest rainfall. Winds blew predominantly from the southwesterly to westerly sector<\/strong> (SSW, WNW, W, and SW being the most frequent directions), averaging a moderate 2.6 m\/s<\/strong>. The strongest gust of the month, 15.6 m\/s<\/strong>, was measured on 27 May<\/strong> in a brisk westerly flow.<\/p>\n\n\n\n

Rainfall Analysis<\/h4>\n\n\n\n

Total precipitation for May 2026 amounted to 33.0 mm<\/strong>, distributed across ten days with measurable rain, of which five produced 1 mm or more. The rainfall was strongly concentrated in a single mid-month wet spell: between 11 and 15 May, a slow-moving low-pressure system delivered 22.6 mm \u2014 over two-thirds of the monthly total \u2014 with the wettest single day being 13 May at 12.6 mm<\/strong>. A secondary, lighter event on 19 May contributed 5.4 mm, and early-month rain on 4 May added 3.6 mm. Outside these episodes the month was largely dry, with the final week recording no precipitation at all.<\/p>\n\n\n\n

Against the historical May mean of 28.4 mm<\/strong> (station records 2004\u20132025), the 2026 total of 33.0 mm represents approximately 116 %<\/strong> of the long-term average \u2014 a modestly wet outcome, though comfortably within the normal range. As the chart below illustrates, May rainfall at this station is highly variable, ranging from a remarkably arid 1.0 mm in 2024 to 58.5 mm in 2011. May 2026 sits in the upper-middle portion of this distribution, close to the totals of 2005, 2016, and 2025, and continues the recovery from the extreme dryness of May 2024.<\/p>\n\n\n\n
