Living in the country, I've found that when seasons change, water quality and alkalinity seems to change with it. This brings different water quality, which can harbour more bioburden, and with that comes stronger smells from the water. At this time of the year, it just is what it is. In the city however, you have better quality water standards, so the issue should be more in line with scum or bioburden on the drain line. As molds or "scum" forms on the drain lines, it forms a hardened surface in order to preserve its cellular properties. This is most likely causing the smell, so you'll need to unscrew the "p" trap under the sink, and use a brush to scrape it clean. Then, you'll need to use a flexible, longer brush or router attachment that is used specifically for drain clearing, and scrub out the remainder of the line as far as the brush or router will allow. Using hot water won't do much of anything, mold is quite temp resistant. If, after cleaning, the smell continues, you may need to use a stronger solvent to essentially disinfect the line, but that is a last resort, as bleach will effectively kill off any of the useful bacteria that aids in breakdown of organic materials in the city drain and septic systems, and smells will only become stronger after that. If, after doing all of this, you find that the smell still exists, you may need to contact a professional to see if the problem is further down the line in the main drain that goes to the city owned lines.
