We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. The clearer part of the year in Lima begins around April 15 and lasts for 6.2 months, ending around October 21. The month with the highest number of rainy days is August (2 days). Lima, Peru - December weather averages including high and low temperatures, humidity, rainfall, snowfall, daylight, sunshine, UV index, and sea temperature. Based on weather reports collected during 1985–2015. 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. On February 20, the cloudiest day of the year, the sky is overcast or mostly cloudy 80% of the time, and clear, mostly clear, or partly cloudy 20% of the time. The day, twilights (civil, nautical, and astronomical), and night are indicated by the color bands from yellow to gray. : Recommended tours for 2021/2022, Priceline: Exclusive 7% off hotels worldwide, Intrepid Travel: Top deals on 2021/2022 tours, Where to book family holidays with free child places, Where to go on holiday in December for the best weather, Quarantine-free holidays & Covid Cover with TUI, Where to go on holiday in July for the best weather, Where to go on holiday in May for the best weather, Travelzoo: Top offers with fully refundable vouchers, Save on hotels, restaurants, spas & more with Travelzoo, Book online with fully refundable vouchers, Filter vouchers by theme, price, type & more, Book 2021 tours to worldwide destinations at 2020 prices, Travel between 1st Jan & 31st Dec 2021 (inclusive). Within 50 miles also contains extreme variations in elevation (16,483 feet). We nevertheless include the chart below as an illustration of the distribution of temperatures experienced throughout the year. The coldest month (with the lowest average sea temperature) is September (15.8°C). Lima does not experience significant seasonal variation in the frequency of wet days (i.e., those with greater than 0.04 inches of liquid or liquid-equivalent precipitation). There is only a single weather station, Jorge Chávez International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Lima. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands. For each hour between 8:00 AM and 9:00 PM of each day in the analysis period (1980 to 2016), independent scores are computed for perceived temperature, cloud cover, and total precipitation.
