36°C Gulf Heat Meets 1°C Moscow Chill as Bangkok Drenched

Over the next 24 hours from 05:31 UTC on Saturday 31 October 2026, the biggest contrast is between the hot Gulf and South Asia and a cold Europe. Karachi, Riyadh and Doha climb to 36°C (97°F), while Moscow drops to 1°C (34°F) overnight. The heaviest rain falls in Bangkok, with 19.6 mm.

Hot in the Gulf, cold in Moscow

The warmth is concentrated around the Arabian Peninsula and Pakistan’s coast. Karachi, Riyadh and Doha are all mostly sunny and reach 36°C. Jeddah and Dubai are close behind at 35°C (95°F). Moscow, by contrast, only reaches 8°C (46°F) under cloud and then cools to near freezing overnight.

Middle East and South Asia weather

Across the Middle East, skies are mostly sunny and dry, with Dubai the exception: it sees light showers but only 0.3 mm. Inland and further north it is far gentler, with Tehran at 23°C (73°F) and Cairo at 27°C (81°F). Istanbul is cooler at 16°C (61°F) and cloudy.

In South Asia, northern cities such as Lahore, Islamabad and Delhi are dry and mostly sunny, with highs between 26°C and 28°C. The wet weather is further south and east. Colombo gets heavy rain, about 16.3 mm, and Kolkata, Dhaka and Kathmandu all have rain. Mumbai, Chennai and Bengaluru see only light showers.

Southeast Asia rain: Bangkok heavily hit

Bangkok is the wettest big city on the map, with heavy rain and 19.6 mm even though it is hot at 34°C (93°F). Rain also falls in Ho Chi Minh City, Singapore, Jakarta, Kuala Lumpur, Manila and Hanoi, though totals there are smaller. With so much warmth and moisture in the air, expect humid, showery conditions across the region.

Europe: fog, cloud and a wet pocket

Much of western Europe is dominated by fog. London, Manchester, Dublin and Amsterdam all start grey, and Manchester reaches only 12°C (54°F). Berlin, Zurich, Stockholm, Oslo and Helsinki are cloudy and cool. Paris, Madrid, Lisbon and Rome are mostly sunny, and Lisbon is the warmest of them at 25°C (77°F). Rain is the story in Athens, with 9.7 mm, and in Vienna, with 3.7 mm. Reykjavík is wet and breezy, with winds up to 33 km/h.

Americas, Africa and Oceania

In North America, Miami has heavy rain, about 13.1 mm, with winds up to 33 km/h. Phoenix is unusually wet for a desert city, with 9.2 mm. The north-east is drier: Boston and New York are mostly sunny, though Boston is chilly at 10°C (50°F) with winds up to 23 km/h. Los Angeles and Chicago have rain, but only small amounts.

In South America, Santiago gets 6.7 mm of rain and São Paulo and Bogotá are wet too. In Africa, Nairobi has rain, about 8.3 mm, while Johannesburg is warm at 31°C (88°F) and Cape Town is breezy, with winds up to 31 km/h.

What it means for travellers and people outdoors

• In the Gulf and Karachi, keep to shade at midday, drink water often and plan outdoor activity for earlier or later in the day.
• Bangkok and Colombo travellers should allow extra time for journeys in heavy rain and carry waterproofs.
• Fog across the UK, Ireland and the Netherlands can slow roads and flights, so check before leaving.
• Sydney and Reykjavík are windy, so secure loose items and expect a rougher time near the coast.
• In Moscow, wrap up for a night near freezing.
