Residents in Colchester should prepare for a week of changeable weather, as the Met Office forecasts a mix of sunshine and rain between 11 May and 17 May 2026. While conditions will remain largely within seasonal norms, the combination of brisk winds and passing showers means the weather will feel cooler than actual temperature readings throughout the week.
Temperatures across the week are expected to range from 13°C to 18°C, with Sunday predicted to be the warmest day. However, residents may notice a chill in the air, especially on Monday night, when strong winds are expected to make temperatures feel as low as 0°C. Winds will pick up significantly by mid-week, with gusts reaching up to 39mph on Wednesday afternoon.
Those planning to be outdoors should remain prepared for quick changes in conditions. While Tuesday is expected to be the driest day of the week, Wednesday afternoon carries a high probability of heavy rain, with chances of precipitation reaching 95% between 2pm and 5pm. Monday morning also sees a high likelihood of rain, with a 70% chance of showers expected around 11am.
Despite the unsettled conditions, UV levels are forecast to reach high levels on Monday, Tuesday, Wednesday, and Friday. Experts recommend that residents take precautions against the sun during midday hours, such as wearing sunscreen or seeking shade, when spending time outside. Fortunately, those with allergies will find some relief, as both pollen and air pollution levels are expected to remain low throughout the week.
While this week’s temperatures are hovering close to the average May highs of 16°C, according to AccuWeather data, the rapid shifts between rain and sunshine are a reminder of the variable spring weather patterns typically seen across the East of England.
