Forecasts and climate averages
Should I use the forecast or monthly averages?
Use the forecast for the days it covers. Monthly averages help compare seasons for a later trip; they cannot predict the weather on a particular future day.
What if a forecast is unavailable?
The page cannot provide current conditions for that request. You can still use any recorded climate information, but it is not a substitute for a current forecast.
Where does the weather data come from?
Provider links and available dates appear with the weather information. Forecast data and climate summaries have different periods and should be read separately.
