— Met Office (@metoffice) April 7, 2026 How weather conditions influence pollen Different elements of the weather affect pollen in different ways. Warm, wet weather earlier in the season supports plant growth and pollen development. Once pollen is ready to be released, warm and dry conditions

description of tropical storm activity for each basin can be found below. All statistics are calculated using observed data to 1 st December 2015. 2.1 North Atlantic The 2015 Atlantic hurricane season recorded 11 tropical storms (winds ≥ 39 mph), of which only 4 became hurricanes (winds ≥ 74 mph) and 2

to 24 hours earlier, with double figures likely in many places. Alongside the warmth, wet and windy weather will return, particularly in the northwest where strong winds are expected Thursday night into Friday. Weekend outlook The weekend could bring some interesting developments. A low-pressure

distribution to air frost. However, those places into which cold air can drain are particularly prone to frost. Examples include Altnaharra (Highland) with an average of 73 air frosts per year. In Northern Scotland the frost-free season is o en as little as 3 months, as shown by the average

that falls in these seasons. In summer, convection caused by solar surface heating sometimes forms shower clouds and a large proportion of rain falls from showers and thunderstorms then. A further factor that greatly affects the rainfall distribution is altitude. Moist air that is forced to ascend hills

member of RCM-PPE that gives lower PSS values though). This is consistent with the large (and significant) cold and wet biases seen in the north of the UK in this model in this season (Figures 16 and 18). The nested CPM-MRI reduces the contribution to the total rainfall from days with high rainfall

The latest Met Office ‘State of the UK Climate’ report has been published today, examining the weather of 2022 in the context of long-term climate records.   The report highlights how the UK’s climate continues to change, with recent decades warmer, wetter and sunnier than the 20th century

is gained. A climate of a particular place is often described in seasonal periods (e.g. summer/ winter or rainy/ dry season) over the cycle of the year. The climate can also naturally vary between different years due to the process of Earth system cycles, especially those associated with large

hours. Notable weather Storm Ashley, the first named storm of the 2024/25 season, brought wet and windy weather to the UK between 20-21 October with the strongest winds across north-western areas. While crossing the Atlantic the area of low pressure interacted with a powerful jet stream

The main rain season is from February through May, and short rains from 2 October to November, and the dry periods are June to September and December to February (Figure 5
