Actual Forecast Location: We have 830+ weather locations on the worldtravelguide.net website. Where no exact location is available we have used the nearest appropriate forecast point.
Symbols indicate the predominant weather for the day in question, calculated based on a weighting of different types of weather. So if a day is forecast to be sunny with the possibility of a brief shower, then we will see a sunny or partly cloudy symbol rather than a rain cloud.
The maximum temperature is the highest temperature forecast between dawn and dusk, and the minimum temperature is the lowest temperature expected from dusk on the day in question to dawn the next day. The temperature is in °C, or Celsius.
Wind speed and direction are the conditions expected at midday. Wind direction is based on a 16 point compass. W, SW, SSW, etc. The wind direction states where the wind originates. Wind speed is listed in MPH or miles per hour.

  • 51 to 70 is moderate to low
  • 71 to 80 is moderate
  • 81 to 90 is moderate to high
