Last year was bitterly cold and the crowds stood in heavy rain to pay their respects.
But the weather forecast for this year looks better, with only a very small chance of a shower during the commemorations.
The Met Office says temperatures will get to around 10C and the morning is expected to be dry, with just a 10% of a light shower by midday.
The BBC's forecast predicts temperatures of around 11C and less than a 10% chance of rain throughout the day. Winds will be around 15mph.
