May has been a month of extremes with warm start, cool middle (coolest since 2010) followed by arguably one of Britain and Ireland’s most exceptional heatwaves. Just a week ago, it was running firmly below average, now, like March and April, warmer than average to complete a firmly warmer than average spring of 2026. As […]

For UK and Ireland, April 2026 was wet through 1st half, dry 2nd half and generally mild for all with decent warmth to end. Another warm one for west and north, cool, wet east of Europe. Global temp & precip anomaly for April 2026 Europe UK Stats/Highlights April showers in shorter supply, but sunshine plentiful […]
May 2026 shall open warm and sunny with widespread low 20s up and down the British Isles with even warm into France and Iberia while it’s wintry on the opposite end of the continent. 26/27C possible in SE England Friday. However, this warm and dry West/cold, wet East contrast looks to quickly even itself out […]
March and spring’s opening month was dominated by a strongly +AO/NAO with a deep trough stretching from Alaska to Greenland with strong ridging over North America & Europe. Unfortunately the below 500mb geopotential anomaly below only goes out to the 17th. The ridging over North America and eastern Europe was unusually strong and persistent… This […]
While Easter doesn’t fall on the same dates each year, we’ve witnessed all weather types and seasons with dates ranging from as early as March 22nd and as late as April 25th. Quite as few past Easter weekend’s have produced a little bit of everything given the high volatility ‘transition’ from winter to summer. The […]
The westerlies continued on from mid January through much of February as well as March, reflected nicely with a persistent +AO/NAO. Warmer than average has been the rule but not without a chillier end to the month as per my March Outlook. From late winter to early spring, rainfall distribution returned to a typical climatalogical […]
The period mid January through mid February was dominated by an unusually strong/south shifted and zonal jet stream, initiated by strong high latitude blocking (forcing jet south) and large thermal contrast over North America (stronger jet). The 3rd piece to what produced ‘unusual persistence’ and shift in distribution of wind and precipitation was unusually strong […]
The pattern which carried through the back half of January largely continued in February with dominant westerlies. A distinct cool North, mild South for not only UK but Europe. Cold and dry Scandi & Baltic Region, exceptionally mild and wet France/Spain/Portugal. See February Recap! Is there any hints of change into the first month of […]
The period between January 15th and February 10th will go down as one of the coldest and snowiest in recent decades for Eastern North America. The result of a stretched polar vortex with similarity to 2013-14 and 2014-15. Tweet by Ben Noll (Feb 13th) It’s been the coldest winter in more than two decades for […]
