Weather in July
Temperature
July is the month when Astoria experiences its warmest temperatures, averaging a high of 81.1°F (27.3°C) and a low of 62.1°F (16.7°C).Heat index
July's heat index is estimated at a hot 86°F (30°C). If exposure and activity are sustained, they might cause a feeling of weariness, resulting in heat cramps.Understand that the heat index values take into account shaded locations and mild winds. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
