Hourly Weather Forecast Tabular Forecast. Local Climate Information Weather Alerts! The predominant average hourly wind direction in Manchester is from the west throughout the year. Manchester is located near a large body of water e. This section reports on the wide-area average surface temperature of that water. The average water temperature experiences significant seasonal variation over the course of the year.

The time of year with warmer water lasts for 3. The time of year with cooler water lasts for 3. To characterize how pleasant the weather is in Manchester throughout the year, we compute two travel scores. Based on this score, the best time of year to visit Manchester for general outdoor tourist activities is from late June to mid September , with a peak score in the third week of August. Based on this score, the best time of year to visit Manchester for hot-weather activities is from early July to mid August , with a peak score in the last week of July.

For each hour between AM and PM of each day in the analysis period to , independent scores are computed for perceived temperature, cloud cover, and total precipitation.

Those scores are combined into a single hourly composite score, which is then aggregated into days, averaged over all the years in the analysis period, and smoothed. Our cloud cover score is 10 for fully clear skies, falling linearly to 9 for mostly clear skies, and to 1 for fully overcast skies.

Our precipitation score , which is based on the three-hour precipitation centered on the hour in question, is 10 for no precipitation, falling linearly to 9 for trace precipitation, and to 0 for 0. The growing season in Manchester typically lasts for 5. Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature.

Based on growing degree days alone, the first spring blooms in Manchester should appear around April 22 , only rarely appearing before April 8 or after May 1. This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents.

Shortwave radiation includes visible light and ultraviolet radiation. The average daily incident shortwave solar energy experiences extreme seasonal variation over the course of the year.

The brighter period of the year lasts for 3. The brightest month of the year in Manchester is July , with an average of 6. The darker period of the year lasts for 3. The darkest month of the year in Manchester is December , with an average of 1. For the purposes of this report, the geographical coordinates of Manchester are The topography within 2 miles of Manchester contains only modest variations in elevation, with a maximum elevation change of feet and an average elevation above sea level of feet.

Within 10 miles contains only modest variations in elevation 1, feet. Within 50 miles contains very significant variations in elevation 3, feet. This report illustrates the typical weather in Manchester, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, to December 31, There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Manchester.

For each station, the records are corrected for the elevation difference between that station and Manchester according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations. The estimated value at Manchester is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Manchester and a given station.

To get a sense of how much these sources agree with each other, you can view a comparison of Manchester and the stations that contribute to our estimates of its temperature history and climate.

Please note that each source’s contribution is adjusted for elevation and the relative change present in the MERRA-2 data. All data relating to the Sun’s position e. This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a kilometer grid.
