When drawing up the calendar, existing contracts must be taken into account, based, among other things, on the best possible weather conditions in the country visited. For example, this is why Miami is in May, because later there would be a risk of entering hurricane season. And the reason for this almost one-month break is precisely the fixed dates and the movements between the 2023 and 2024 calendars and the short time for adjustments.
In this part of the year, there were the Japanese GP and the Qatar GP, and both were moved to 2024. Now, the Qatar GP has been moved to a triple final between Las Vegas and Abu Dhabi. But the ‘culprit’ was someone else, the Japanese GP, which was to take place right after Singapore, and was brought forward to the spring of 2024, placing it closer to China. So the reason there is a four-week break without races is that the move of the Japanese GP was agreed too late for the organisers of other GPs to also agree to move their stages.
Specifically, the problem was that at that time there was no room for movement, because the Singapore GP was already scheduled for the weekend of 20-22 September, because as the Marina Bay circuit is an urban circuit, the city is closed, which requires some planning. Formula 1's plan B was then to move the United States GP, but as a triple-header on the American continent with Mexico and Brazil (with no break in between) was planned, it was not possible to move forward.
I feel like there isn't really anything to worry about for the breaks, because if they need it to give us better entertainment then I am all for it. Plus it gives teams a chance to do upgrades, and that means things could change. Imagine if we come back and red bull has this insanely good upgrade and they are good enough hto battle McLaren again, things would change suddenly and we would have a lot of fun.
Or maybe Mclaren would be even more dominant, or maybe none of them will make big changes but some team unexpected like Williams suddenly do podiums and such. Not saying that will happen, just saying this break increases the possibility of something like that and I am happy about it.
This should not be all that bad, and we could consider this as a good thing. If nothing else, racing every week is hard on the body, and racing 20+ times a year isn't easy already, giving break just so their body would recover is great, remember these racers lose few kilos each race, so it's definitely not easy on the body neither.
