The heaviest rain is in Istanbul, with 19.4 mm and winds up to 44 km\/h, and Miami has the strongest winds at 55 km\/h.<\/p>\n<h2>The big contrast: 37\u00b0C heat against a 1\u00b0C chill<\/h2>\n<p>The forecast window runs from 05:30 UTC on Tuesday 27 October 2026. Across southern Asia and the Gulf, summer has not let go. Karachi, Mumbai and Jeddah all reach 37\u00b0C under mostly sunny skies. Meanwhile in East Asia, clear skies let the night get cold, so Seoul drops to 1\u00b0C before warming to 13\u00b0C in the afternoon. That is a gap of 36 degrees between the two extremes.<\/p>\n<h2>South Asia and the Middle East: heat stays put<\/h2>\n<p>Dhaka is cloudy but very warm, with 36\u00b0C by day and only 28\u00b0C at night, so there is little relief after dark. Doha reaches 36\u00b0C and Dubai 35\u00b0C, with Dubai seeing winds up to 28 km\/h. Riyadh also reaches 35\u00b0C. Further north the air is far gentler: Tehran peaks at 22\u00b0C and Cairo at 30\u00b0C.<\/p>\n<p>Not everywhere in South Asia is hot and dry. Colombo has heavy rain with 16.9 mm and winds up to 32 km\/h, and Kolkata sees rain with 5.2 mm. Lahore and Islamabad stay dry and mostly sunny at 28\u00b0C and 26\u00b0C.<\/p>\n<h2>Europe: fog in the east, rain in the west and south<\/h2>\n<p>Eastern Europe is the cold side of the continent. Vienna and Warsaw start with fog and only reach 12\u00b0C, with lows of 2\u00b0C. Moscow is cloudy with a high of 9\u00b0C. Reykjav\u00edk is colder still at 5\u00b0C, with rain.<\/p>\n<p>Istanbul takes the worst of the weather, with heavy rain of 19.4 mm and winds up to 44 km\/h. Athens has 8.8 mm of rain, and Oslo has 7.2 mm. Helsinki stays dry but cloudy, with winds up to 41 km\/h. London, Paris, Amsterdam and Manchester all see rain, but totals are modest. Madrid and Rome stay dry and mostly sunny, at 22\u00b0C and 20\u00b0C.<\/p>\n<h2>North America: heavy rain in Miami and Seattle<\/h2>\n<p>Miami combines heavy rain of 16.6 mm with the day&#8217;s strongest winds, up to 55 km\/h, although it stays warm at 27\u00b0C. On the opposite coast, Seattle has heavy rain of 10.5 mm and a high of 13\u00b0C. Vancouver is also wet with 9.8 mm. Much of the east and centre is dry: New York reaches 15\u00b0C, and Denver warms to 18\u00b0C after a 2\u00b0C start.<\/p>\n<h2>Tropics and the rest of the world<\/h2>\n<p>The tropics are in their usual rainy mood. Kuala Lumpur has heavy rain of 15.5 mm, Lagos 14.2 mm and Jakarta 10.3 mm. Hong Kong is rainy with winds up to 41 km\/h. In the southern hemisphere, Melbourne and Brisbane see rain, while Sydney and Perth stay mostly sunny.<\/p>\n<h2>What it means for travellers and people outdoors<\/h2>\n<ul>\n<li>In Karachi, Mumbai, Jeddah, Doha and Dhaka, plan outdoor activity for the cooler parts of the day, drink plenty of water and take breaks in shade.<\/li>\n<li>In Seoul, Vienna, Warsaw and Moscow, expect a cold start, so dress in layers. Fog in Vienna and Warsaw may slow morning travel.<\/li>\n<li>In Istanbul and Miami, allow extra time for journeys, as heavy rain and strong winds can make travel slower.<\/li>\n<li>In Seattle and Colombo, carry waterproofs and expect wet surfaces.<\/li>\n<\/ul>\n<h2>The numbers<\/h2>\n<div class=\"wf-table\">\n<table>\n<thead>\n<tr>\n<th>City<\/th>\n<th>High<\/th>\n<th>Low<\/th>\n<th>Rain<\/th>\n<th>Sky<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Karachi, Pakistan<\/td>\n<td>37\u00b0C<\/td>\n<td>24\u00b0C<\/td>\n<td>0.0 mm<\/td>\n<td>mostly sunny<\/td>\n<\/tr>\n<tr>\n<td>Mumbai, India<\/td>\n<td>37\u00b0C<\/td>\n<td>24\u00b0C<\/td>\n<td>0.0 mm<\/td>\n<td>mostly sunny<\/td>\n<\/tr>\n<tr>\n<td>Jeddah, Saudi Arabia<\/td>\n<td>37\u00b0C<\/td>\n<td>28\u00b0C<\/td>\n<td>0.0 mm<\/td>\n<td>mostly sunny<\/td>\n<\/tr>\n<tr>\n<td>Dhaka, Bangladesh<\/td>\n<td>36\u00b0C<\/td>\n<td>28\u00b0C<\/td>\n<td>0.0 mm<\/td>\n<td>cloudy<\/td>\n<\/tr>\n<tr>\n<td>Seoul, South Korea<\/td>\n<td>13\u00b0C<\/td>\n<td>1\u00b0C<\/td>\n<td>0.0 mm<\/td>\n<td>mostly sunny<\/td>\n<\/tr>\n<tr>\n<td>Vienna, Austria<\/td>\n<td>12\u00b0C<\/td>\n<td>2\u00b0C<\/td>\n<td>0.0 mm<\/td>\n<td>fog<\/td>\n<\/tr>\n<tr>\n<td>Warsaw, Poland<\/td>\n<td>12\u00b0C<\/td>\n<td>2\u00b0C<\/td>\n<td>0.0 mm<\/td>\n<td>fog<\/td>\n<\/tr>\n<tr>\n<td>Moscow, Russia<\/td>\n<td>9\u00b0C<\/td>\n<td>2\u00b0C<\/td>\n<td>0.0 mm<\/td>\n<td>cloudy<\/td>\n<\/tr>\n<tr>\n<td>Istanbul, Turkey<\/td>\n<td>14\u00b0C<\/td>\n<td>12\u00b0C<\/td>\n<td>19.4 mm<\/td>\n<td>heavy rain<\/td>\n<\/tr>\n<tr>\n<td>Colombo, Sri Lanka<\/td>\n<td>28\u00b0C<\/td>\n<td>25\u00b0C<\/td>\n<td>16.9 mm<\/td>\n<td>heavy rain<\/td>\n<\/tr>\n<tr>\n<td>Miami, United States<\/td>\n<td>27\u00b0C<\/td>\n<td>23\u00b0C<\/td>\n<td>16.6 mm<\/td>\n<td>heavy rain<\/td>\n<\/tr>\n<tr>\n<td>Kuala Lumpur, Malaysia<\/td>\n<td>31\u00b0C<\/td>\n<td>24\u00b0C<\/td>\n<td>15.5 mm<\/td>\n<td>heavy rain<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p class=\"wf-note\">Forecast retrieved 27 October 2026, 05:31 UTC for 84 major cities.
