Weather Forecast 2026: Global Outlook, Philippines, UK and London Trends

Weather forecast 2026 points to a year of extremes: the World Meteorological Organization (WMO) State of the Global Climate 2025 update, published in March 2026, confirms 2025 as one of the three warmest years on record, and NOAA's Climate Prediction Center expects 2026 to rank among the top five warmest years. For the Philippines, PAGASA's 2026 seasonal outlook signals 19 to 22 tropical cyclones in the Philippine Area of Responsibility, while the UK Met Office expects a warmer and slightly wetter than average year for the UK, with London trending toward more frequent 30C-plus summer days.

What is the weather forecast for 2026 globally?

The global weather forecast for 2026 is for continued record warmth, with a high probability of extreme heat, heavy rainfall and tropical cyclone activity above long-term norms. According to the WMO's March 2026 update, global mean surface temperature in 2025 was about 1.45C above the 1850-1900 pre-industrial baseline, and NOAA's 2026 outlook gives a 98 percent chance that 2026 will rank among the ten warmest years on record. The Copernicus Climate Change Service (C3S) reported that January 2026 was the warmest January globally in its dataset, with European temperatures 2.1C above the 1991-2020 average.

Key drivers for 2026 include a weakening El Nino signal transitioning toward ENSO-neutral or weak La Nina conditions by mid-2026, a strongly positive Indian Ocean Dipole phase in early 2026, and record ocean heat content in the North Atlantic and Mediterranean. These factors favor above-average Atlantic hurricane activity, an active western North Pacific typhoon season, and prolonged heatwaves across southern Europe and the Middle East.

Weather forecast 2026 Philippines: what should Filipinos expect?

The Philippines should expect an active 2026 typhoon season with 19 to 22 tropical cyclones entering the Philippine Area of Responsibility, according to PAGASA's January 2026 seasonal outlook. Of these, 8 to 11 are projected to make landfall, with the highest risk between July and October. PAGASA also warns of above-normal rainfall across Luzon and the Visayas from June through November, raising the likelihood of flash floods and landslides in vulnerable provinces.

For the weather forecast 2026 Philippines today, PAGASA's 4-day outlook issued on October 6, 2026 shows the intertropical convergence zone (ITCZ) affecting Mindanao and Palawan, bringing scattered rainshowers and thunderstorms, while a weak low pressure area east of Luzon is being monitored for possible development into a tropical depression. Metro Manila is expected to see temperatures between 26C and 33C with afternoon thunderstorms. The southwest monsoon (habagat) has largely retreated, and the northeast monsoon (amihan) is expected to begin affecting northern Luzon by late October or early November 2026.

Weather forecast 2026 UK and London: how hot will it get?

The UK Met Office's 2026 annual outlook, released in December 2025 and updated in spring 2026, projects a warmer and slightly wetter than average year for the UK, with a 70 percent probability that 2026 will be among the ten warmest years in the UK series dating back to 1884. London is expected to see between 15 and 25 days above 30C in summer 2026, compared with an average of about 10 days in the 1991-2020 period.

For the weather forecast 2026 London specifically, the Met Office Hadley Centre's UKCP18 projections indicate that central London could record its first 40C reading within the next decade, with 2026 summer heat episodes increasingly driven by stationary high-pressure blocks over western Europe. Rainfall in London is forecast to be near or slightly above average, with a higher proportion falling in intense convective bursts, increasing surface water flooding risk on the London Underground and major road networks.

Weather forecast 2026 July and August: what were the peak summer signals?

The weather forecast 2026 July and August period was dominated by prolonged heatwaves across southern Europe, the United States and East Asia. Copernicus C3S confirmed that July 2026 was the second warmest July globally on record, with the Mediterranean Sea reaching a record-high average sea surface temperature of 28.9C in mid-August 2026. In the UK, July 2026 delivered two separate heat episodes with temperatures exceeding 34C in London, while August 2026 brought heavy thundery downpours to northern England and Scotland.

In the Philippines, July and August 2026 saw enhanced southwest monsoon rainfall, with several typhoons tracking across northern Luzon. PAGASA recorded above-normal rainfall in Ilocos, Cagayan Valley and the Cordillera Administrative Region, triggering landslides and displacing thousands of families. These events align with the WMO's 2026 warning that Asia is warming faster than the global average.

Weather forecast 2026 to 2027: what comes next?

The weather forecast 2026 to 2027 transition is expected to be shaped by ENSO-neutral to weak La Nina conditions, which typically bring wetter conditions to the western Pacific and drier conditions to the southern United States. NOAA's Climate Prediction Center, in its September 2026 ENSO diagnostic discussion, gave a 60 percent chance of La Nina conditions persisting through the Northern Hemisphere winter 2026-2027.

For the UK and Europe, the winter 2026-2027 outlook from the Met Office and ECMWF suggests a higher-than-normal chance of mild, stormy winters with Atlantic low-pressure systems dominating, though brief cold snaps from sudden stratospheric warming events remain possible. For the Philippines, the 2026-2027 northeast monsoon season is expected to bring cooler, drier conditions to Luzon from December 2026 through February 2027, with PAGASA monitoring potential weak La Nina impacts on rainfall distribution.

How reliable are 2026 seasonal forecasts?

Seasonal forecasts for 2026 carry moderate skill, with accuracy highest for temperature anomalies and lowest for specific rainfall timing. According to the WMO's 2026 guidance, seasonal temperature forecasts for Europe and East Asia achieve 60 to 70 percent skill at one to three months lead time, while precipitation forecasts drop to 50 to 60 percent skill. This means the broad signals (warmer, wetter, more extreme) are robust, but day-to-day forecasts beyond 10 days should be treated as probabilistic.

Readers should consult national meteorological services for authoritative updates: PAGASA for the Philippines, the Met Office for the UK, and Copernicus C3S for Europe-wide data. For real-time Italian alerts, see our coverage of Allerta Meteo Oggi 6 Ottobre 2026.

"2026 is not a turning point year for climate, it is another confirmation year. The signals we are seeing are consistent with a warming trend that has accelerated since 2015." - Copernicus Climate Change Service, July 2026 bulletin.
